Dear Hui,

I've found patch v8 will cause build fail because pwrap node hasn't been 
merged according to [1] and [2] (mt8192). However, the pwrap node for 
mt8195 is already in [3] mt8195.dtsi. The mt8195 boards using mt6359 
will need mt6359.dtsi for enabling more peripherals.

I think to split the mt8192 part into the other patch in next version 
could reduce the dependencies between mt6359.dtsi and mt8192.dtsi at 
this stage. Hence we don't need to wait pwrap node be merged in mt8192.dtsi.

After that, you can have my Reviewed-by tag in next version.
