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.
