V7:
- The bulk of the patches for this series have been merged.
  There are still four patches to be pushed/updated.
- Adds clocks for msm8974 - Dmitry
- Adds compat strings for sm8150, sm8350, sm8450, sm8550 - Dmitry
- Changes last patch in series to state - Rob
  compatible:
    contains:
      const: qcom,mdss-dsi-ctrl

V6:
- Squashes a number of patches per Krzysztof's comments on bisectability
- Adds in Acked-by Rob and Krzysztof 

V5:
- Adds compat strings to bindings/display/msm/qcom,SoC-mdss.yaml - Dmitry
- Re-orders simple fixes to the start of the series to allow backports - Dmitry 
- VDDA and drop of node-names - Krzysztof
- Deprecates qcom,dsi-ctrl-6g-qcm2290 - Krzysztof, Dmitry
- Expands set of updated files to include new msm8953 - bod
- Converts to agreed compat string qcom,SoC-dsi-ctrl hence
  -              - qcom,mdss-dsi-ctrl-msm8996
  +              - qcom,msm8996-dsi-ctrl
- Adds RB where indicated for the compat strings.
V4:
- Moves the update of the example from patch #5 to patch #4

V3:
- Moves declaration of mdss-dsi-ctrl into compat string declaration
  patch - Krzysztof, Dmitry
- Renames qcm-2290 compat string to agreed compat "qcom,socname-dsi-ctrl"
  Dmirty, Krzysztof
- Adds empty line after if clause in yaml control flow section - Dmirty
- Adds Rb/Ack - Krzysztof, Dmitry, Doug, David
- vdd*
  Looking into this some more, I don't believe vdd, vdda, vddio ought to be
  required properties. Its up to the PCB manufacturer and the panel in-use
  how that panel is powered. Powering the panel is not something that
  even necessarily needs to be done from the dsi-ctrl driver.
  Originally marking vdd* as required in the .txt was an error, its not a
  SoC level dtsi requirement.
- clock-names
  Rather than replicate the clock-name in each if block I listed them with
  a specific description from a similar reference in usb/qcom,dwc3.yaml.

V2:

- Moves the DSI PHY changes to a different later series.
  There are enough dsi-controller-main changes to justify its own
  standalone series.

- The original phy-name binding change given discussion with Rob and
  Krzysztof became its own standalone series that has since been merged.

- Retains the drop of power-domain from yaml as a required property.
  I dug into the available dtsi. The apq8064 doesn't appear to have any
  GDSC which can be attached as a power-domain, which means the
  power-domain requirement is not universal across the various silicon
  versions.

- Adds Dmitry's RB to power-domain drop

- For the clock declarations I've
  * I noticed that the simple change I had worked for msm8939 but
    subsquently broke other dtsi which drove a bigger change to document
    the clocks on a per compatible basis.
  * Added compat strings in yaml.
  * Moved the allOf down later in the file to acomodate the if/then.
  * Number of clocks validated on a per compatible basis
  * The driver code which doesn't care about the number of clocks
    can still operate on the mdss-dsi-ctrl compat but the dts checks will
    validate against the compat string and yaml.

- vdd descriptions
  Took the previous text I missed from the .txt file - Krzysztof, Dmitry
  Adds vdd, vdda and vddio to the required list. This exposes warnings in
  existing dtsi but the previous .txt declared these regulators as
  required. - Krzysztof

V1:
This series fixes up a number of dtbs checks which are being flagged adding
in the msm8939 dtsi.

When converting from .txt to .yaml a number of the parameters for the older
msm8916 silicon were not transmitted into the yaml.

Adding in the msm8939 which is a near 1:1 copy of the msm8916 in terms of
dtsi triggers a rake of dtbs checks as a result.
