[PATCH v3 0/3] drm/msm/hdmi: turn MSM8996 HDMI PHY into OF clock provider

[PATCH v3 0/3] drm/msm/hdmi: turn MSM8996 HDMI PHY into OF clock provider

[Dmitry Baryshkov]

On MSM8996 the HDMI PHY is the QMP PHY, it provides an HDMI PLL clock
used by the MMCC. Add support for providing this clock to the OF
framework by registerding the clock provider and adding #clock-cells
property to the DT node.

The dt-bindings from this series depends on changes from [1] (part of
linux-next, but not of the msm-next yet).

[1]: https://patchwork.freedesktop.org/series/104836/

Changes since v2:
- Added minItems: 2 to clock-names property (Rob)
- Explicitly mentioned dependencies

Changes since v1:
- Also handle the xo clock (include it into the dtsi, use parent_data
  instead of parent_names). The patches were changed, so I didn't pick
  up the R-b tags.

[PATCH v3 1/3] dt-bindings: phy: qcom,hdmi-phy-qmp: add clock-cells and XO clock

[Dmitry Baryshkov]

As the QMP HDMI PHY is a clock provider, add constant #clock-cells
property. For the compatibility with older DTs the property is not
marked as required. Also add the XO clock to the list of the clocks used
by the driver.

[PATCH v3 2/3] drm/msm/hdmi: make hdmi_phy_8996 OF clk provider

[Dmitry Baryshkov]

On MSM8996 the HDMI PHY provides the PLL clock to the MMCC. As we are
preparing to convert the MSM8996 to use DT clocks properties (rather
than global clock names), register the OF clock provider.

While we are at it, also change the driver to use clk_parent_data rather
parent_names to setup a link to the XO clock.

[PATCH v3 2/3] drm/msm/hdmi: make hdmi_phy_8996 OF clk provider

[Dmitry Baryshkov]

On MSM8996 the HDMI PHY provides the PLL clock to the MMCC. As we are
preparing to convert the MSM8996 to use DT clocks properties (rather
than global clock names), register the OF clock provider.

While we are at it, also change the driver to use clk_parent_data rather
parent_names to setup a link to the XO clock.

Add #clock-cells property to the HDMI PHY device node to let other nodes
resolve the hdmipll clock. While we are at it, also add the XO clock to
the device node.

Bjorn, I'm picking the patches 1,2 into msm-next. Could you please pick 
this patch into your dts-for-6.1?
