[PATCH 0/2] ALSA/ASoC/SOF: SSP dev_type support
by Peter Ujfalusi 26 Mar '24

26 Mar '24

Hi, SOF always passed 0 as dev_type to intel_nhlt_get_endpoint_blob() when looking up the blob from the NHLT table. This causes issues since alsa-utils commit 3a47ef2487ed ("topology: nhlt: intel: support more device types and directions") The dev_type is no longer always 0 in the topology embedded NHLT table resulting lookup failures for analog codecs since they will have dev_type=4. With SOF the dev_type is not used, we always use the SSP port index for looking up the configuration blob. The solution for the issue is to fetch the dev_type for the SSP port and feed it back to the intel_nhlt_get_endpoint_blob() to be able to find the configuration regardless of the assigned dev_type.

[PATCH v9 00/27] Add support for QMC HDLC, framer infrastructure and PEF2256 framer
by Herve Codina 14 Mar '24

14 Mar '24

Hi, I have a system where I need to handle an HDLC interface and some audio data. The HDLC data are transferred using a TDM bus on which a PEF2256 (E1/T1 framer) is present. The PEF2256 transfers data from/to the TDM bus to/from the E1 line. This PEF2256 is connected to a PowerQUICC SoC for the control path and the TDM is connected to the SoC (QMC component) for the data path. From the QMC HDLC driver, I need to handle HDLC data using the QMC, carrier detection using the PEF2256 (E1 line carrier) and set/get some PEF2256 configuration. The QMC HDLC driver considers the PEF2256 as a generic framer. It performs operations that involve the PEF2256 through the generic framer API. The audio data are exchanged with the PEF2256 using a CPU DAI connected to the TDM bus through the QMC and the PEF2256 needs to be seen as a codec in order to be linked to the CPU DAI. The codec handles the carrier detection using the PEF2256 and reports the carrier state to the ALSA subsystem using the ASoC jack detection. The codec, even if instantiated by the PEF2256 driver, considers the PEF2256 as a generic framer. The generic framer has: - 2 consumers (QMC HDLC drv and codec) - 1 provider (PEF2256) So, the design is the following: +------------------+ +---------+ | QMC | <- TDM -> | PEF2256 | <-> E1 +---------+ | +-------------+ | | | | CPU DAI | <-data--> | QMC channel | | | | +---------+ | +-------------+ | | | +--------------+ | +-------------+ | | | | QMC HDLC drv | <-data--> | QMC channel | | | | +--------------+ | +-------------+ | | | ^ +------------------+ | | | +--------+ +-------------+ | | +-> | framer | <-> | PEF2256 drv | <- local bus ->| | | | | | +---------+ +-> | | | | | +--------+ | +-------+ | +-------------------> | codec | | | +-------+ | +-------------+ Further more, the TDM timeslots used by the QMC HDLC driver need to be configured at runtime (QMC dynamic timeslots). Several weeks ago, I sent two series related to this topic: - Add the Lantiq PEF2256 audio support [1] - RFC Add support for QMC HDLC and PHY [2] This current series is a rework of these two series taking into account feedbacks previously received. In order to implement all of this, I do the following: 1) Perform some fixes (patches 1, 2, 3, 4, 5 ) 2) Introduce the QMC HDLC driver (patches 6, 7, 8) 3) Add QMC dynamic timeslot support (patches 9 - 19) 4) Add timeslots change support in QMC HDLC (patch 20) 5) Introduce framer infrastructure (patch 21) 6) Add PEF2256 framer provider (patches 22, 23, 24, 25) 7) Add framer codec as a framer consumer (patch 26) 8) Add framer support as a framer consumer in QMC HDLC (patch 27) The series contains the full story and detailed modifications. If needed, the series can be split and/or commits can be squashed. Let me know.

[PATCH v7 0/5] ASoC: makes CPU/Codec channel connection map more generic
by Kuninori Morimoto 14 Mar '24

14 Mar '24

Hi Mark Cc Bard, Pierre-Louis, Jerome, DT-ML This is v7 patch-set. Current ASoC is supporting CPU/Codec = N:M (N < M) connection by using ch_map idea. This patch-set expands it that all connection uses this idea, and no longer N < M limit [1][2]. Link: https://lore.kernel.org/r/87fs6wuszr.wl-kuninori.morimoto.gx@renesas.com [1] Link: https://lore.kernel.org/r/878r7yqeo4.wl-kuninori.morimoto.gx@renesas.com [2] ASoC core code ([PATCH 1/5]) is same as v6 and it was tested by Pierre-Louis, and Jerome. Big change on v7 is basically for Audio-Graph-Card2. v6 -> v7 - use "endpoint" for N:M connection instead of ch-map-idx on Audio-Graph-Card2 v5 -> v6 - tidyup some warnings - rename "ch-map-idx" -> "channel-map-index" - Update "channel-map-index" description - add Tested-by from Pierre-Louis / Jerome v4 -> v5 - use cpu/codec index on ch_maps - separate card2 sample DT patch into prepare and new feature - ch-maps -> ch-map-idx on DT v3 -> v4 - add Jerome on To - add "description" on "ch-maps" v2 -> v3 - tidyup comment - use more clear connection image on DT - "ch_maps" -> "ch-maps" on DT - Add DT maintainer on "To:" for all patches v1 -> v2 - makes CPU/Codec connection relation clear on comment/sample - fixup type "connction" -> "connection" - makes error message clear Kuninori Morimoto (5): ASoC: makes CPU/Codec channel connection map more generic ASoC: audio-graph-card2: use better image for Multi connection ASoC: audio-graph-card2: add CPU:Codec = N:M support ASoC: audio-graph-card2-custom-sample: Add connection image ASoC: audio-graph-card2-custom-sample: add CPU/Codec = N:M sample include/sound/soc.h | 56 ++- .../audio-graph-card2-custom-sample.dtsi | 380 ++++++++++++++++-- sound/soc/generic/audio-graph-card2.c | 277 ++++++++++--- sound/soc/intel/boards/sof_sdw.c | 28 +- sound/soc/soc-core.c | 95 ++++- sound/soc/soc-dapm.c | 45 +-- sound/soc/soc-pcm.c | 44 +- 7 files changed, 754 insertions(+), 171 deletions(-) -- 2.25.1

[PATCH v3] powerpc: macio: Make remove callback of macio driver void returned
by Dawei Li 13 Mar '24

13 Mar '24

Commit fc7a6209d571 ("bus: Make remove callback return void") forces bus_type::remove be void-returned, it doesn't make much sense for any bus based driver implementing remove callbalk to return non-void to its caller.

[PATCH] ALSA: dice: add stream format parameters for Weiss devices
by Michele Perrone 29 Feb '24

29 Feb '24

Hard-coded stream format parameters are added for Weiss Engineering FireWire devices. When the device vendor and model match, the parameters are copied into the stream format cache. This allows for setting all supported sampling rates up to 192kHz, and consequently adjusting the number of available I/O channels.

[PATCH 00/13] irqchip: Convert to platform remove callback returning void
by Uwe Kleine-König 27 Feb '24

27 Feb '24

this series converts all drivers below drivers/irqchip to use .remove_new(). See commit 5c5a7680e67b ("platform: Provide a remove callback that returns no value") for an extended explanation and the eventual goal. The TL;DR; is to make it harder for driver authors to leak resources. The drivers touched here are all fine though and don't return early in .remove(). So all conversions in this series are trivial.

[PATCH] slimbus: core: Remove usage of the deprecated ida_simple_xx() API
by Christophe JAILLET 21 Feb '24

21 Feb '24

ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_range() is inclusive. So change this change allows one more device. Previously address 0xFE was never used. Fixes: 46a2bb5a7f7e ("slimbus: core: Add slim controllers support") Signed-off-by: Christophe JAILLET <christophe.jaillet(a)wanadoo.fr> --- /!\ Untested /!\ The change of behavior is motivated by the comment in drivers/slimbus/slimbus.h stating that /* Manager's logical address is set to 0xFF per spec */, so all other values, including 0xFE should be valid, IMHO.

can't find the source of the problem or a way to solve it. Is there anything I might be missing? I assume the problem is that it's trying to write to the registers after the suspend has happened, but I haven't been able to prove that either, and I wouldn't know how to fix that. Could that be what's happening here? Thanks.

[PATCH v8 00/13] Introduce STM32 Firewall framework
by Gatien Chevallier 03 Feb '24

03 Feb '24

Introduce STM32 Firewall framework for STM32MP1x and STM32MP2x platforms. STM32MP1x(ETZPC) and STM32MP2x(RIFSC) Firewall controllers register to the framework to offer firewall services such as access granting. This series of patches is a new approach on the previous STM32 system bus, history is available here: https://lore.kernel.org/lkml/20230127164040.1047583/ The need for such framework arises from the fact that there are now multiple hardware firewalls implemented across multiple products. Drivers are shared between different products, using the same code. When it comes to firewalls, the purpose mostly stays the same: Protect hardware resources. But the implementation differs, and there are multiple types of firewalls: peripheral, memory, ... Some hardware firewall controllers such as the RIFSC implemented on STM32MP2x platforms may require to take ownership of a resource before being able to use it, hence the requirement for firewall services to take/release the ownership of such resources. On the other hand, hardware firewall configurations are becoming more and more complex. These mecanisms prevent platform crashes or other firewall-related incoveniences by denying access to some resources. The stm32 firewall framework offers an API that is defined in firewall controllers drivers to best fit the specificity of each firewall. For every peripherals protected by either the ETZPC or the RIFSC, the firewall framework checks the firewall controlelr registers to see if the peripheral's access is granted to the Linux kernel. If not, the peripheral is configured as secure, the node is marked populated, so that the driver is not probed for that device. The firewall framework relies on the access-controller device tree binding. It is used by peripherals to reference a domain access controller. In this case a firewall controller. The bus uses the ID referenced by the access-controller property to know where to look in the firewall to get the security configuration for the peripheral. This allows a device tree description rather than a hardcoded peripheral table in the bus driver. The STM32 ETZPC device is responsible for filtering accesses based on security level, or co-processor isolation for any resource connected to it. The RIFSC is responsible for filtering accesses based on Compartment ID / security level / privilege level for any resource connected to it. STM32MP13/15/25 SoC device tree files are updated in this series to implement this mecanism. Changes in V8: - Add missing "simple-bus" compatible in STM32MP13/25 SoC device tree files for the ETZPC/RIFSC nodes - Add missing dependency on OF for OF_DYNAMIC that is selected by STM32_FIREWALL Changes in V7: - Separate indentation changes from access-controllers changes in the device tree file commits - Select OF_DYNAMIC when STM32_FIREWALL is set in order to use of_detach_node() in the firewall framework - Handle previously non-present RNG and HASH nodes in the STM32MP13 device tree file Changes in V6: - Rename access-controller to access-controllers - Remove access-controller-provider - Update device trees and other bindings accordingly - Rework ETZPC/RIFSC bindings to define what access-controllers cells contain inside #access-controller-cells - Some other minor fixes Changes in V5: - Integrate and rework the "feature-domains" binding patch in this patchset. The binding is renamed to "access-controller" - Rename every feature-domain* reference to access-control* ones - Correct loop bug and missing select STM32_FIREWALL in 32-bit platform Kconfig Changes in V4: - Fix typo in commit message and YAML check errors in "dt-bindings: Document common device controller bindings" Note: This patch should be ignored as stated in the cover letter. I've done this to avoid errors on this series of patch - Correct code syntax/style issues reported by Simon Horman - Added Jonathan's tag for IIO on the treewide patch Changes in V3: Change incorrect ordering for bindings commits leading to an error while running "make DT_CHECKER_FLAGS=-m dt_binding_check" Changes in V2: generic: - Add fw_devlink dependency for "feature-domains" property. bindings: - Corrected YAMLS errors highlighted by Rob's robot - Firewall controllers YAMLs no longer define the maxItems for the "feature-domains" property - Renamed st,stm32-rifsc.yaml to st,stm32mp25-rifsc.yaml - Fix examples in YAML files - Change feature-domains maxItems to 2 in firewall consumer files as there should not be more than 2 entries for now - Declare "feature-domain-names" as an optional property for firewall controllers child nodes. - Add missing "feature-domains" property declaration in bosch,m_can.yaml and st,stm32-cryp.yaml files firewall framework: - Support multiple entries for "feature-domains" property - Better handle the device-tree parsing using phandle+args APIs - Remove "resource firewall" type - Add a field for the name of the firewall entry - Fix licenses RIFSC: - Add controller name - Driver is now a module_platform_driver - Fix license ETZPC: - Add controller name - Driver is now a module_platform_driver - Fix license Device trees: - Fix rifsc node name - Move the "ranges" property under the "feature-domains" one Gatien Chevallier (12): dt-bindings: treewide: add access-controllers description dt-bindings: bus: document RIFSC dt-bindings: bus: document ETZPC firewall: introduce stm32_firewall framework of: property: fw_devlink: Add support for "access-controller" bus: rifsc: introduce RIFSC firewall controller driver arm64: dts: st: add RIFSC as an access controller for STM32MP25x boards bus: etzpc: introduce ETZPC firewall controller driver ARM: dts: stm32: add ETZPC as a system bus for STM32MP15x boards ARM: dts: stm32: put ETZPC as an access controller for STM32MP15x boards ARM: dts: stm32: add ETZPC as a system bus for STM32MP13x boards ARM: dts: stm32: put ETZPC as an access controller for STM32MP13x boards Oleksii Moisieiev (1): dt-bindings: document generic access controllers .../access-controllers.yaml | 84 + .../bindings/bus/st,stm32-etzpc.yaml | 87 + .../bindings/bus/st,stm32mp25-rifsc.yaml | 96 + .../bindings/crypto/st,stm32-cryp.yaml | 4 + .../bindings/crypto/st,stm32-hash.yaml | 4 + .../devicetree/bindings/dma/st,stm32-dma.yaml | 4 + .../bindings/dma/st,stm32-dmamux.yaml | 4 + .../devicetree/bindings/i2c/st,stm32-i2c.yaml | 4 + .../bindings/iio/adc/st,stm32-adc.yaml | 4 + .../bindings/iio/adc/st,stm32-dfsdm-adc.yaml | 4 + .../bindings/iio/dac/st,stm32-dac.yaml | 4 + .../bindings/media/cec/st,stm32-cec.yaml | 4 + .../bindings/media/st,stm32-dcmi.yaml | 4 + .../memory-controllers/st,stm32-fmc2-ebi.yaml | 4 + .../bindings/mfd/st,stm32-lptimer.yaml | 4 + .../bindings/mfd/st,stm32-timers.yaml | 4 + .../devicetree/bindings/mmc/arm,pl18x.yaml | 4 + .../bindings/net/can/bosch,m_can.yaml | 4 + .../devicetree/bindings/net/stm32-dwmac.yaml | 4 + .../bindings/phy/phy-stm32-usbphyc.yaml | 4 + .../bindings/regulator/st,stm32-vrefbuf.yaml | 4 + .../devicetree/bindings/rng/st,stm32-rng.yaml | 4 + .../bindings/serial/st,stm32-uart.yaml | 4 + .../bindings/sound/st,stm32-i2s.yaml | 4 + .../bindings/sound/st,stm32-sai.yaml | 4 + .../bindings/sound/st,stm32-spdifrx.yaml | 4 + .../bindings/spi/st,stm32-qspi.yaml | 4 + .../devicetree/bindings/spi/st,stm32-spi.yaml | 4 + .../devicetree/bindings/usb/dwc2.yaml | 4 + MAINTAINERS | 7 + arch/arm/boot/dts/st/stm32mp131.dtsi | 1063 ++++--- arch/arm/boot/dts/st/stm32mp133.dtsi | 51 +- arch/arm/boot/dts/st/stm32mp13xc.dtsi | 19 +- arch/arm/boot/dts/st/stm32mp13xf.dtsi | 19 +- arch/arm/boot/dts/st/stm32mp151.dtsi | 2756 +++++++++-------- arch/arm/boot/dts/st/stm32mp153.dtsi | 52 +- arch/arm/boot/dts/st/stm32mp15xc.dtsi | 19 +- arch/arm/mach-stm32/Kconfig | 1 + arch/arm64/Kconfig.platforms | 1 + arch/arm64/boot/dts/st/stm32mp251.dtsi | 7 +- drivers/bus/Kconfig | 10 + drivers/bus/Makefile | 1 + drivers/bus/stm32_etzpc.c | 141 + drivers/bus/stm32_firewall.c | 294 ++ drivers/bus/stm32_firewall.h | 83 + drivers/bus/stm32_rifsc.c | 252 ++ drivers/of/property.c | 2 + include/linux/bus/stm32_firewall_device.h | 141 + 48 files changed, 3352 insertions(+), 1938 deletions(-) create mode 100644 Documentation/devicetree/bindings/access-controllers/access-controllers.yaml create mode 100644 Documentation/devicetree/bindings/bus/st,stm32-etzpc.yaml create mode 100644 Documentation/devicetree/bindings/bus/st,stm32mp25-rifsc.yaml create mode 100644 drivers/bus/stm32_etzpc.c create mode 100644 drivers/bus/stm32_firewall.c create mode 100644 drivers/bus/stm32_firewall.h create mode 100644 drivers/bus/stm32_rifsc.c create mode 100644 include/linux/bus/stm32_firewall_device.h -- 2.25.1
