Subject: [PATCH v3 00/11] clk: qcom: Introduce clocks drivers for SM8650

This patchset introduces the following SM8650 Clock drivers:
- GCC: Global Clock Controller
- DISPCC: Display Clock Controller
- TCSR Clock Controller
- GPUCC: GPU Clock Controller driver
- rpmh clocks

Dependencies: None

For convenience, a regularly refreshed linux-next based git tree containing
all the SM8650 related work is available at:
https://git.codelinaro.org/neil.armstrong/linux/-/tree/topic/sm8650/upstream/integ

Changes in v3:
- Use sm8550 tcsr bindings instead of a new one
- split GCC driver in 2 to pass the mailinig lists 100k chars limit, no code change
- collected review tags
- Link to v2: https://lore.kernel.org/r/20231030-topic-sm8650-upstream-clocks-v2-0-144333e086a2@linaro.org

Changes in v2:
- Fix Copyright headers
- Fix include in all c files
- Use "select GCC" instead of "depends on GCC"
- GCC:
  - remove UBWCP clocks until we know how to use them
  - switch to clk_rcg2_shared_ops when needed
  - use RETAIN_FF_ENABLE and/or VOTABLE GDSC flasgs when needed
  - add GDSC collapse_ctrl/mask when needed
  - fix "Keep the critical clock always-On" comments
- TCRSCC: use qcom_cc_probe()
- DISPCC: fix runtime_pm_sync on error
- rpmh: expand comment on clk3a
- Link to v1: https://lore.kernel.org/r/20231025-topic-sm8650-upstream-clocks-v1-0-c89b59594caf@linaro.org
