[PATCH v6 0/4] Enable wm8524 on i.MX8MQ-EVK

[PATCH v6 0/4] Enable wm8524 on i.MX8MQ-EVK

[Daniel Baluta]

On i.MX8MQ EVK we can start the party using the wm8524 codec
which gets it's data through the SAI2 interface.

In order to make it work this patch series enables the SDMA nodes,
sets the correct pinctrl configuration and uses the simple card
machine driver to put everything together.

Changes since v5:
	- remove clocks and clock-names properties from wm8524
	code node as they are not used.

Changes since v4 (after Fabio's review)
	- removed mclk0 from sai2 node because it is not yet supported
	  by SAI driver
	- s/audio-codec-0/audio-codec
	- squashed patches 4 and 5

Changes since v3:
	- use "arm64: dts: imx8mq-evk" prefix for patches specific to
	  8MQ-EVK
	- squash together patches for setting up SAI (previous 3/5 and
	  4/5)
	- add back and document "fsl, imx8mq-sdma" compatbile string

Changes since v2:
        - s/QM/MQ after Chris comments

Changes since v1:
        - added cover letter
        - remove "fsl,imx8mq-sdma" compatible for sdma.

Reviewed-by tag should go after your SoB, since that's the sequence of

There shouldn't be a space in the imx8mq compatible string.

Oh, nice catch. This patch series is already in so care to send a fix?

Otherwise, I will take care of it.

[PATCH v6 4/4] arm64: dts: imx8mq-evk: Enable audio codec wm8952

[Daniel Baluta]

The main Audio DAC used on the EVK board is wm8952.
The EVK provides the MCLK to wm8952.

Digital interface is SAI2 which includes three signals:
SYNC_CLK, BCLK and DACDAT.

This patch sets:
	* SAI2 pinctrl configuration
	* clock hierarchy
	* wm8960 codec

Then uses simple-card machine driver to connect them
into a sound card.

Please rebase to my for-next branch.

Please have a newline between properties and child node ...

... and between nodes as well.

Please try to keep pinctrl nodes sort alphabetically.
