[PATCH 1/3] ASoC: dt-bindings: irondevice, sma1303: Rework binding and add missing properties

[Kiseok Jo]

Fix according to the writing-schema.rst file and tested.
Add the missing property as compatible, reg, sys-clk-id.

[PATCH 2/3] ASoC: SMA1303: Remove the I2C Retry property in devicetree

[Kiseok Jo]

It's necessary to set the value for each device, so remove that.

device probe.

We really shouldn't have this as a custom property, we should be using
a combination of the clock bindings.

In the driver this would turn into using clk_get() to get the MCLK, then
we can query the rate with clk_get_rate() and use option 0 or 1 if the
rate matches, or the PLL otherwise.  If we fail to get MCLK then we can
fall back to using BCLK.

Okay, I got it.
I'll make it based on what you sent me using other drivers.
Thanks, your feedback.

What's the output of 'make dt_binding_check'? Asking since linux-next 
has been broken in different ways with this schema.

2 logs and 2 files output below:
  DTEX  irondevice,sma1303.example.dts
  DTC_CHK  irondevice,sma1303.example.dtb

And I didn't see any other error, so I thought it was okay.
Is there anything else I need to check or how? I'll try it.

Thank you!
