The MSC SM2-MB-EP1 carrier board for the SM2S-IMX8PLUS SMARC module has an
NXPP SGTL5000 audio codec connected to I2S-0 (sai2).
This requires to:
* add the power supplies (always on)
* enable sai2 with pinmuxes
* reparent the CLKOUT1 clock that feeds the codec SYS_MCLK to
IMX8MP_CLK_24M in order it to generate an accurate 24 MHz rate

Do you have some downstream patches for the sai interfaces? AFAIR Marek
worked on this but the patches are not mainlien yet.

I would have two patches for your series first is necessary the other is
changing the sound-card to make use of the simple-audio-card.

Right, my patch is based on the v3 series by Marek, and it should be
threaded accordingly
(https://lore.kernel.org/linux-arm-kernel/[email protected]/),
but I realize I haven't made it 100% clear -- sorry about this.
I guess I should just resend separately with a clarifying cover letter
next time.

Why WM8524 ? The MX8MP EVK I have here is populated with WM8960 chip and
with single headphone jack, are you sure the below is correct ?
