[PATCH v5 0/2] Read _SUB from ACPI to be able to identify firmware
by Stefan Binding 05 Jul '22

05 Jul '22

CS35L41 has a DSP which is able to run firmware, as well as a tuning file. Different systems may want to use different firmwares and tuning files, and some firmwares/tunings may not be compatible with other systems. To allow a system to select the correct fimware/tuning, we can read an _SUB from the ACPI. This _SUB can then be used to uniquely identify the system in the firmware/tuning file name. Add a helper function which reads the _SUB, so this can be used by other parts in the future. Add support inside the CS35L41 ASoC driver to read this _SUB, and save it appropriately. Changes since v4: - Rename function Changes since v3: - Fix 32 bit format string warning Changes since v2: - Fix error in function prototype Changes since v1: - Add length validation for SSID String - Rename API - Allocate memory inside API - Use ACPI_HANDLE macro instead of ACPI_COMPANION - Improve error handling Stefan Binding (2): ACPI: utils: Add api to read _SUB from ACPI ASoC: cs35l41: Read System Name from ACPI _SUB to identify firmware drivers/acpi/utils.c | 38 ++++++++++++++++++++++++++++++++++++++ include/linux/acpi.h | 6 ++++++ sound/soc/codecs/cs35l41.c | 24 ++++++++++++++++++++++++ 3 files changed, 68 insertions(+) -- 2.25.1

[PATCH v4 00/14] Canaan devicetree fixes
by Conor Dooley 05 Jul '22

05 Jul '22

From: Conor Dooley <conor.dooley(a)microchip.com> Hey all, This series should rid us of dtbs_check errors for the RISC-V Canaan k210 based boards. To make keeping it that way a little easier, I changed the Canaan devicetree Makefile so that it would build all of the devicetrees in the directory if SOC_CANAAN. I *DO NOT* have any Canaan hardware so I have not tested any of this in action. Since I sent v1, I tried to buy some since it's cheap - but could out of the limited stockists none seemed to want to deliver to Ireland :( I based the series on next-20220617. Thanks, Conor. Changes since v3: - dts: drop the bogus "regs" property pointed out by Niklas - dma/timer: add Serge's reviews (and expand on the dma interrupt description) - dts: add Niklas' T-b where I felt it was suitable. lmk if you think it applies more broadly - spi: drop the applied spi dt-binding change. Thanks Mark. Changes since v2: - i2s: added clocks maxItems - dma: unconditionally extended the interrupts & dropped canaan compatible - timer: as per Sergey, split the timer dts nodes in 2 & drop the binding patch - ili9341: add a canaan specific compatible to the binding and dts Changes since v1: - I added a new dt node & compatible for the SRAM memory controller due Damien's wish to preserve the inter-op with U-Boot. - The dw-apb-ssi binding now uses the default rx/tx widths - A new patch fixes bus {ranges,reg} warnings - Rearranged the patches in a slightly more logical order Conor Dooley (14): dt-bindings: display: convert ilitek,ili9341.txt to dt-schema dt-bindings: display: ili9341: document canaan kd233's lcd ASoC: dt-bindings: convert designware-i2s to dt-schema dt-bindings: dma: dw-axi-dmac: extend the number of interrupts dt-bindings: memory-controllers: add canaan k210 sram controller riscv: dts: canaan: fix the k210's memory node riscv: dts: canaan: fix the k210's timer nodes riscv: dts: canaan: fix mmc node names riscv: dts: canaan: fix kd233 display spi frequency riscv: dts: canaan: use custom compatible for k210 i2s riscv: dts: canaan: remove spi-max-frequency from controllers riscv: dts: canaan: fix bus {ranges,reg} warnings riscv: dts: canaan: add specific compatible for kd233's LCD riscv: dts: canaan: build all devicetress if SOC_CANAAN .../bindings/display/ilitek,ili9341.txt | 27 ------ .../display/panel/ilitek,ili9341.yaml | 49 +++++++--- .../bindings/dma/snps,dw-axi-dmac.yaml | 7 +- .../memory-controllers/canaan,k210-sram.yaml | 52 ++++++++++ .../bindings/sound/designware-i2s.txt | 35 ------- .../bindings/sound/snps,designware-i2s.yaml | 94 +++++++++++++++++++ arch/riscv/boot/dts/canaan/Makefile | 10 +- arch/riscv/boot/dts/canaan/canaan_kd233.dts | 6 +- arch/riscv/boot/dts/canaan/k210.dtsi | 73 +++++++++----- .../riscv/boot/dts/canaan/sipeed_maix_bit.dts | 2 +- .../boot/dts/canaan/sipeed_maix_dock.dts | 2 +- arch/riscv/boot/dts/canaan/sipeed_maix_go.dts | 2 +- .../boot/dts/canaan/sipeed_maixduino.dts | 2 +- 13 files changed, 253 insertions(+), 108 deletions(-) delete mode 100644 Documentation/devicetree/bindings/display/ilitek,ili9341.txt create mode 100644 Documentation/devicetree/bindings/memory-controllers/canaan,k210-sram.yaml delete mode 100644 Documentation/devicetree/bindings/sound/designware-i2s.txt create mode 100644 Documentation/devicetree/bindings/sound/snps,designware-i2s.yaml base-commit: 6cc11d2a1759275b856e464265823d94aabd5eaf -- 2.37.0

[PATCH] ASoC: xilinx: Suppress second error message about reset failure in .remove()
by Uwe Kleine-König 05 Jul '22

05 Jul '22

Returning an error value in a platform remove callback results in an error message being emitted by the platform core, but otherwise it doesn't make a difference. If ret is != 0, there is already an error message and another very generic doesn't add any value, so return 0 unconditionally. This is a preparation for making platform remove callbacks return void.

Hi Mark, All, Just a question. Can you explain me the proper way to configure eq1 and eq2 of max98089 using sound/soc/codecs/max98088.c driver? Could be a valid solution fetching eq1, eq2 bands params from dts? Let me know.
