If possible I do prefer a solution, which uses only DTS.
Side question - how to refer to baud clock from [1]?
Just add a property to this cpu node like:
clock = <&clks IMX6QDL_CLK_SSI2>;
Ok.
system-clock-frequency = <XXXX>;
This would not be necessary unless you want to specify a clock rate
so as to override the clock rate configuration in hw_params().
Ok.
This is the right solution based on current simple-card driver. For
SSI (having two clocks), you have to specify the baud clock in the
cpu node like that. I believe this is what the simple-card designer
expected users to do since the cpu node is the first place that the
driver tries to look at.
I will give a shoot the option with adding the ipg clock.
No, not ipg clock. You should use the second clock -- baud clock.
Yes. Correct - the baud clock.
