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

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

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

I suspect we need to split the binding because the function list needs
to change. Can you make a whole new file that's probably largely a copy
of this file and/or extract the common bits into a meta schema and
include that in both the files? Then the function list can be different
and the clock property can be omitted in the sc7280 file.

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.

As most are common functions and fixed number of LPASS Lpi pin
configuration across platforms,

Only diff is ADSP bypass platforms 2 clocks are optional. Otherwise
clock design also same for SC7280 and SM8250 based architecture.

So I feel Keeping common file is better for now.

I don't agree. We want to be very strict about what is exposed. It needs
to match exactly what is supported on the SoC, not be a superset of it.
