[0/6] clk: qcom: Add clocks for MSM8909

Message

Stephan Gerhold July 4, 2022, 1:29 p.m. UTC

Add a driver for the Global Clock Controller (GCC) that provides clocks,
resets and power domains for the various hardware blocks in the MSM8909
SoC. Make it possible to have longer delay between assertion/deassertion
of particular reset signals (this is needed for the USB PHY on MSM8909).
Finally, add the necessary definitions for the clocks controlled by the
RPM firmware on MSM8909.

The patch set is fairly large but most of it is just boring clock
definitions in the GCC driver. And compared to newer SoCs like SC8280XP
with 7k+ lines in the GCC driver this is still fairly small. :-)
