[PATCH 0/6] clk: qcom: Add video clock controller and resets for X1E80100

[Stephan Gerhold]

In preparation of adding iris (video acceleration) for Qualcomm X1E80100,
enable support for the video clock controller and additional needed reset
controls. Since iris in X1E is largely identical to SM8550, reuse the
existing videocc-sm8550 driver with slightly adjusted PLL frequencies and
adapt the reset definitions from the SM8550 GCC driver.

[PATCH 1/6] dt-bindings: clock: qcom,sm8450-videocc: Document X1E80100 compatible

[Stephan Gerhold]

X1E80100 videocc is largely identical to SM8550, but needs slightly
different PLL frequencies. Add a separate qcom,x1e80100-videocc compatible
to the existing schema used for SM8550.

[PATCH 2/6] clk: qcom: videocc-sm8550: Allow building without SM8550/SM8560 GCC

[Stephan Gerhold]

From the build perspective, the videocc-sm8550 driver doesn't depend on
having one of the GCC drivers enabled. It builds just fine without the GCC
driver. In practice, it doesn't make much sense to have it enabled without
the GCC driver, but currently this extra dependency is inconsistent with
most of the other VIDEOCC entries in Kconfig. This can easily cause
confusion when you see the VIDEOCC options for some of the SoCs but not for
all of them.

Let's just drop the depends line to allow building the videocc driver
independent of the GCC selection. Compile testing with randconfig will also
benefit from keeping the dependencies minimal.

[PATCH 3/6] clk: qcom: videocc-sm8550: Add separate frequency tables for X1E80100

[Stephan Gerhold]

X1E80100 videocc is identical to the one in SM8550, aside from slightly
different recommended PLL frequencies. Add the separate frequency tables
for that and apply them if the qcom,x1e80100-videocc compatible is used.

Hm, so this is actually gcc_video_axi0_clk (same reg), but the bit
indeed is described to pass on a reset signal to the hw block on
the other side

[PATCH 6/6] arm64: dts: qcom: x1e80100: Add videocc

[Stephan Gerhold]

Add the video clock controller for X1E80100, similar to sm8550.dtsi. It
provides the needed clocks/power domains for the iris video codec.

we don't expose it through the clk framework on Linux (it's
enabled through magic writes instead)
