[PATCH v5 0/4] clk: qcom: Add support for SM8150 rpmh

[PATCH v5 0/4] clk: qcom: Add support for SM8150 rpmh

[Vinod Koul]

Add support for rpm clock controller found in SM8150 and while at it update
the driver to support parent data clock scheme as suggested by Stephen.

Changes since v4:
 - Fix the .fw_name as xo instead of xo_board (v4 erroneously did for
   .name)

Changes since v3:
 - Make clock parent name as xo instead of xo_board

Changes since v2:
 - Add reviewed-by from Bjorn
 - Update the parent name as xo_board
 - Fix style issue

Changes since v1:
 - Describe parent clocks for rpmhcc
 - Add support for parent data scheme for rpmhcc

Vinod Koul (4):
  dt-bindings: clock: Document the parent clocks
  clk: qcom: clk-rpmh: Convert to parent data scheme
  dt-bindings: clock: Document SM8150 rpmh-clock compatible
  clk: qcom: clk-rpmh: Add support for SM8150

[PATCH v5 1/4] dt-bindings: clock: Document the parent clocks

[Vinod Koul]

With clock parent data scheme we must specify the parent clocks for the
rpmhcc nodes. So describe the parent clock for rpmhcc in the bindings.
