Subject: [PATCH v4 0/2] Enable wm8524 codec on i.MX8MM EVK

From: Daniel Baluta <[email protected]>

This patch series introduces the SAI nodes on i.MX8MM EVK then
creates the wm8524 codec node and finally uses simple card machine
driver to create a sound card.

Changes since v3:
- rebased on latest for-next branch
- fixed encoding problems

Changes since v2:
- place compatible strings one a single lines
- move GPIO pinctrl in a node of its own
- remove codec phandle

Changes since v1:
- use "fsl,imx8mm-sai", "fsl,imx8mq-sai" compatbile strings and
remove "fsl,imx6sx-sai" because SAI module on i.MX8M is not
compatbile with SAI modules form i.MX6

Shawn, although here https://lkml.org/lkml/2019/5/31/110 you
say this patch is applied I couldn't find it in any of your

Subject: [PATCH v4 2/2] arm64: dts: imx8mm-evk: Enable audio codec wm8524

From: Daniel Baluta <[email protected]>

i.MX8MM has one wm8524 audio codec connected with
SAI3 digital audio interface.

This patch uses simple-card machine driver in order
to enable wm8524 codec.

We need to set:
* SAI3 pinctrl configuration
* codec reset gpio pinctrl configuration
* clock hierarchy
* codec node
* simple-card configuration

Shawn,

Care to have a look at this? git send-email should correctly work now.

Let me know if you want me to resend
