Subject: [PATCH v6 0/6] SM8350 Display/GPU clock enablement

Changes since v2
- Dropped "clk: Introduce CLK_ASSUME_ENABLED_WHEN_UNUSED"
- Dropped "clk: qcom: sm8250-dispcc: Flag shared RCGs as assumed enable"
- Dropped "clk: qcom: rcg2: Cache rate changes for parked RCGs"

Changes since v3:
- Dropped RBs & SoBs for bigger changes
- Changed author to me for patches with big changes

Changes since v5:
- Reverted dispcc-sm8350 split from dispcc-sm8250
and related .index changes - Bjorn
- Re-added Tags that were thrown out due to the
above revert

Subject: [PATCH v6 4/6] clk: qcom: add support for SM8350 DISPCC

From: Jonathan Marek <[email protected]>

Add support to the SM8350 display clock controller by extending the SM8250
display clock controller, which is almost identical but has some minor
differences.
