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 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

RESEND to fix email encoding.

i.MX8MM has 5 SAI instances with the following base
addresses according to RM.

SAI1 base address: 3001_0000h
SAI2 base address: 3002_0000h
SAI3 base address: 3003_0000h
SAI5 base address: 3005_0000h
SAI6 base address: 3006_0000h

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

No SAI4?

I know the RM does not show the SAI4 in the memory map, but the clock
driver does show a SAI4 clock gate.

So it seems we have a contradiction in the reference manual. Could you
please double check with the internal folks?

IMX8MM_CLK_SAI3_ROOT is the internal clock that drives the SAI3
interface, not an external clock that feeds the codec.

It seems you should remove this 'clocks' entry.

<reduce audience to linux-imx>

Shengjiu,

Can you help me with this? Specifically: I couldn't find the schematic
showing the
exact connection pins between SAI and wm8524 codec.

I looked into our internal tree and the wm8524 codec always handles
CLK_SAIX_ROOT
but Fabio has a good point. This clock doesn't feeds the codec.

Unless, we can really look into the schematics and prove it otherwise.

Just checked the schematics and the SAI3_MCLK pin clocks the codec, so
the representation is correct:

Despite the SAI4 confusion, the current patch correctly describe the
SAI interfaces as per the Reference Manual, so:

Yes, I just checked and the devicetree patch is correct. Sorry for the
confusion.

I cannot apply this one, because there are '=20' in the patch content.

Talk to NXP colleague Anson Huang <Anson.Huang@nxp.com> to find out how
to fix it.

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 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
