Subject: [PATCH v2 0/5] Add rpmcc and rpmpd for SM4250/6115

This patch adds support for the RPM clocks and power domains on QCom SM4250 and
SM6115, codename bengal. The rpmcc code is converted from downstream code
(OnePlus repo [1]), and the rpmpd is converted from downstream DT extracted
from OnePlus Nord N100.

The downstream code has additional voter clocks, which let consumers vote and
the driver to select the highest desired clock rate for a given (real) parent
clock [2]. I might port that as well in the near future, let me know if there
is a more elegant solution.

v1: https://lkml.org/lkml/2021/6/22/1171

Changes from v1:
- remove 4250 compatible, both platforms will share one dtsi
- reuse existing clocks as per a0384ecfe2aa ("clk: qcom: smd-rpm: De-duplicate identical entries")

Iskren Chernev (5):
  dt-bindings: soc: qcom: smd-rpm: Add SM6115 compatible
  dt-bindings: clock: qcom: rpmcc: Document SM6115 compatible
  clk: qcom: smd: Add support for SM6115 rpm clocks
  dt-bindings: power: rpmpd: Add SM6115 to rpmpd binding
  drivers: soc: qcom: rpmpd: Add SM6115 RPM Power Domains
