Merge tag 'qcom-clk-for-5.19' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into clk-qcom
Pull Qualcomm clock driver updates from Bjorn Andersson:
This introduces the LPASS clock controller driver for sc7280 and the
global clock controller for SC8280XP.
It adds modem reset, corrects RPM clocks and moves to floor ops for SDCC
on MSM8976. It introduces clocks needed to operate the Sensor Subsystem
in MSM8998.
It enhances the logic for parked shared RCG2s, to avoid problems on
recent platforms. And lastly it introduces a new mechanism for handling
the PCIe pipe_clk, which also needs to be parked on a safe source when
the PHY is turned off.
