Subject: [PATCH v2 0/3] Add pin control support for lpass sc7280

This patch series is to make lpass varient independent pin control
functions common and to add lpass sc7280 pincontrol support.
It also includes dt-bindings for lpass sc7280 lpi compatible.

Changes Since V1:
-- Make lpi pinctrl variant data structure as constant
-- Add appropriate commit message
-- Change signedoff by sequence.

Srinivasa Rao Mandadapu (3):
pinctrl: qcom: Update lpass variant independent functions as generic
dt-bindings: pinctrl: qcom: Add sc7280 lpass lpi pinctrl compatible
pinctrl: qcom: Add SC7280 lpass pin configuration

Subject: [PATCH v2 1/3] pinctrl: qcom: Update lpass variant independent functions as generic

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.

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.

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.

The required power domains are getting enabled in core-boot level. So no
need of reference in this driver.

And still if power domain need to referenced, we can do it from device
tree itself.
