[alsa-devel] [PATCH v2 00/10] Basic sound support for Arndale board / wm8994 updates
This patch series adds basic audio support for Exynos5250 SoC based Arndale board, the Bluetooth receiver source and HDMI output are not covered yet.
There is also one fix for wm8994 driver related to WM1811 CODEC and wm8994 updates to handle MCLK clocks, similar to patches: ae1ea48c5c59 ("ASoC: arizona: Add gating for source clocks of the FLLs") 7a4413d0dc96 ("ASoC: arizona: Add gating for clock when used for direct MCLK")
The main changes since v1: - Fixed bug in "ASoC: wm8994: Add support for MCLKn clock gating" patch (thanks to Charles), - dropped the MFD part patch and moved getting of clocks to the CODEC driver, - Added missing Kconfig entries to patch "ASoC: samsung: arndale: Add support for WM1811 CODEC", - Added a patch renaming the driver and a patch for exynos_defconfig.
Sylwester Nawrocki (10): ASoC: wm8994: Do not register inapplicable controls for WM1811 ASoC: samsung: arndale: Add missing OF node dereferencing ASoC: wm8994: Add support for setting MCLK clock rate ASoC: wm8994: Add support for MCLKn clock gating ASoC: samsung: arndale: Simplify DAI link initialization ASoC: dt-bindings: Document "samsung,arndale-wm1811" compatible ASoC: samsung: arndale: Add support for WM1811 CODEC ASoC: samsung: Rename Arndale card driver ARM: dts: arndale: Add audio support (WM1811 CODEC boards) ARM: exynos_defconfig: Enable Arndale audio driver

In case of WM1811 device there are currently being registered controls referring to registers not existing on that device. It has been noticed when getting values of "AIF1ADC2 Volume", "AIF1DAC2 Volume" controls was failing during ALSA state restoring at boot time: "amixer: Mixer hw:0 load error: Device or resource busy"
Reading some registers through I2C was failing with EBUSY error and indeed these registers were not available according to the datasheet.
To fix this controls not available on WM1811 are moved to a separate array and registered only for WM8994 and WM8958.
There are some further differences between WM8994 and WM1811, e.g. registers 603h, 604h, 605h, which are not covered in this patch.

Thanks, applied.
Best regards, Krzysztof
The patch
ASoC: wm8994: Do not register inapplicable controls for WM1811
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

Changes since v1:
- getting of clocks moved from MFD to the CODEC's driver probe()

The patch
ASoC: wm8994: Add support for MCLKn clock gating
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.

The Arndale boards come with different types of the audio daughter board. In order to support the WM1811 one we add new definition of an ASoC card which will be registered when the driver matches on "samsung,arndale-wm1811" compatible. There is no runtime detection of the audio daughter board type at the moment, compatible string of the audio card needs to be adjusted in DT, e.g. by the bootloader, depending on actual audio board (CODEC) used.

Rename arndale_rt5631.c to just arnddale.c as we support other CODECs than RT5631. While at it replace spaces in Kconfig with tabs.

Add sound node and the clock configurations for the I2S controller for audio support on the Exynos5250 SoC Arndale boards with WM1811 based audio daughter board.
We need to increase drive strength of the I2S bus, otherwise the audio CODEC doesn't work. Likely the CODEC's master clock is the main issue here.
