[alsa-devel] [PATCH] ALSA: aoa-soundbus: Switch to dev_pm_ops
by Lars-Peter Clausen 05 Aug '15

05 Aug '15

Update the aoa-soundbus framework to use dev_pm_ops rather than the deprecated legacy suspend and resume callbacks. Since there isn't anything special to do at the bus level the bus driver does not have to implement any callbacks. The device driver core will automatically pick up and execute the device's PM ops. As there is only a single aoa-soundbus driver implementing suspend and resume, update both the core and driver at the same time to avoid unnecessary code churn.

[alsa-devel] [PATCH] ASoC: tegra: Use devm_clk_get
by Vaishali Thakkar 05 Aug '15

05 Aug '15

This patch introduces the use of managed resource function devm_clk_get instead of clk_get and removes corresponding calls to clk_put in the probe and remove functions. To be compatible with the change various gotos are replaced with direct returns, and unneeded labels are dropped.

This patchset adds support for the Rockchip SPDIF transceiver as present on RK3066, RK3188 and RK3288 boards and enables it on a Radxa rock pro. Tested on a Radxa Rock Pro board. Changes in v2: - Remove platform: module alias as it was unused - Call MODULE_DEVICE_TABLE(of, ) right after the of match table - use rk_spdif as a prefix consistenly throughout the driver - Check return code of regmap_update and bubble it up - Sort the spdif node properties - Drop the 0x prefix from the node name - Rename the spdif@ node to sound@ Sjoerd Simons (4): ASoC: dt-bindings: add rockchip tranceiver bindings ASoc: rockchip: Add rockchip SPDIF transceiver driver ARM: dts: rockchip: Add SPDIF transceiver for RK3188 ARM: dts: rockchip: Add SPDIF optical out on Radxa Rock .../devicetree/bindings/sound/rockchip-spdif.txt | 41 +++ arch/arm/boot/dts/rk3188-radxarock.dts | 19 + arch/arm/boot/dts/rk3188.dtsi | 22 ++ sound/soc/rockchip/Kconfig | 8 + sound/soc/rockchip/Makefile | 2 + sound/soc/rockchip/rockchip_spdif.c | 381 +++++++++++++++++++++ sound/soc/rockchip/rockchip_spdif.h | 63 ++++ 7 files changed, 536 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/rockchip-spdif.txt create mode 100644 sound/soc/rockchip/rockchip_spdif.c create mode 100644 sound/soc/rockchip/rockchip_spdif.h -- 2.5.0

[alsa-devel] [PATCH] ASoC: topology: Update ABI with improvements for TLV, operations and private data.
by Liam Girdwood 05 Aug '15

05 Aug '15

From: Mengdong Lin <mengdong.lin(a)intel.com> This is the kernel patch - a corresponding alsa-lib patch has also been sent. This patch updates the topology ABI version and adds support for private data types, specfic structures for each TLV data type and refactors the operations mapping structure to be generic (so that it can be used by other types). This code is only used within Intel atm and is not in an official alsa-lib release so impact should be minimali for the ABI update. Currently the TLV topology structure is targeted at only supporting the DB scale data. This patch extends support for the other TLV types so they can be easily added at a later stage. TLV structure is moved to common topology control header since it's a common field for controls and can be processed in a general way. Users must set a proper access flag for a control since it's used to decide if the TLV field is valid and if a TLV callback is needed. Removed the following fields from topology TLV struct: - size/count: type can decide the size. - numid: not needed to initialize TLV for kcontrol. - data: replaced by the type specific struct. Added TLV structure to generic control header and removed TLV structure from mixer control. Added generic ops to geneic control header.

Users must set a proper access flag for a control since it's used to decide if the TLV field is valid and if a TLV callback is needed. Removed the following fields from topology TLV struct: - size/count: type can decide the size. - numid: not needed to initialize TLV for kcontrol. - data: replaced by the type specific struct. Added TLV structure to generic control header and removed TLV structure from mixer control. Added generic ops to geneic control header.
