Hi Srinivasa, Thanks for the patches, I think you forgot to add correct mailing list for this drivers.

Please consider using scripts/get_maintainer.pl to help you with this list.

Update pin control variable names to make common for all lpass varients. Update bulk clock voting to optional voting as ADSP bypass platform doesn't need macro and decodec clocks, these are maintained as power domains and operated from lpass audio core cc.

How are you going to ensure that the powerdomains are switched on when setting up the pinctrl configuration.

Should we not take a reference to the power-domain in this driver?

I see your point in first patch making these names more generic, but this is not really going to work, as the above line just added new pin for sm8250 even though it really only has 0-13 pins.

I think it would be more clear if you could just make a dedicated structures for sc7280. Simillar comments apply for other changes too.

Other than that the patch looks good to me.

Okay. agree to your point. As lpass_lpi_pins array is just declaration, and it will be used in functions, I thought it won't impact as functions are different for both architectures.

With your feedback understood that it may not work existing archs. Will change accordingly and re-post it.
