[PATCH v7 0/4] clk: qcom: Add support for SM8550

[PATCH v7 0/4] clk: qcom: Add support for SM8550

[Abel Vesa]

This patchset adds more clocks support for the Qualcomm SM8550 SoC,
It adds the TCSR clock controller driver and the rpmh clocks.

Changes since v7:
 * dropped the first patch which was adding the RPMH_CXO_PAD_CLK and
   RPMH_CXO_PAD_CLK_A IDs
 * dropped the fixed factor divider clocks from RMPh CC, since the
   dividers will be added in devicetree as child nodes of the RPMh CC node.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above

date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

[PATCH v7 4/4] clk: qcom: Add TCSR clock driver for SM8550

[Abel Vesa]

The TCSR clock controller found on SM8550 provides refclks
for PCIE, USB and UFS. Add clock driver for it.

This patch is based on initial code downstream.
