[PATCH v2 01/18] dt-bindings: msm: dsi-controller-main: Fix operating-points-v2 constraint

[Bryan O'Donoghue]

The existing msm8916.dtsi does not depend on nor require operating points.

[PATCH v2 02/18] dt-bindings: msm: dsi-controller-main: Fix power-domain constraint

[Bryan O'Donoghue]

power-domain is required for the sc7180 dispcc GDSC but not every qcom SoC
has a similar dependency for example the aqp8064.

Most Qcom SoC's using mdss-dsi-ctrl seem to have the ability to
power-collapse the MDP without collapsing DSI.

For example the qcom vendor kernel commit for apq8084, msm8226, msm8916, msm8974

https://review.carbonrom.org/plugins/gitiles/CarbonROM/android_kernel_oneplus_msm8994/+/7b5c011a770daa2811778937ed646237a28a8694

"ARM: dts: msm: add mdss gdsc supply to dsi controller device

 It is possible for the DSI controller to be active when MDP is
 power collapsed. DSI controller needs to have it's own vote for
 mdss gdsc to ensure that gdsc remains on in such cases."

This however doesn't appear to be the case for the apq8064 so we shouldn't
be marking power-domain as required in yaml checks.

[PATCH v2 03/18] dt-bindings: msm: dsi-controller-main: Add vdd* descriptions back in

[Bryan O'Donoghue]

When converting from .txt to .yaml we didn't include descriptions for the
existing regulator supplies.

- vdd
- vdda
- vddio

Add those descriptions into the yaml now as they were prior to the
conversion. Mark the supplies as required as was previously the case in the
.txt implementation.

Warnings about missing regulators can be resolved by updating the relevant
dtsi files to point to fixed always-on regulators where appropriate.

Ugh. Are they missing or are they optional/not used on these platforms?
Can you possibly list all regulator warnings?

Some platforms either don't implement them or worse possibly do 
implement but don't model them when they should.

Downstream we have

arch/arm/boot/dts/qcom/msm8916-mdss.dtsi

mdss_dsi0: qcom,mdss_dsi@1a98000 {
	vdda-supply = <&pm8916_l2>;
	vdd-supply = <&pm8916_l17>;
	vddio-supply = <&pm8916_l6>;
};

Looking at something like

arch/arm/boot/dts/qcom/msm8916-mtp.dtsi which references 
arch/arm/boot/dts/qcom/dsi-panel-jdi-1080p-video.dtsi it doesn't appear

Good example. We have vdda-supply and vddio-supply in
msm8916-pm8916.dtsi (correct).
And the mentioned vdd-supply is not applicable to this platform. It
powers up the external DSI-to-HDMI bridge. I'd assume that the same
regulator was destined to power up the panel.

So, I'd suggest defining all supplies at the top level and then
pushing all the required: parts into the per-SoC entries.

Drop "Phandle to" and "device node", so just "VDD regulator". You
describe hardware rather (when applicable), not Devicetree syntax.

The same in other places and with that:

However it might be easier to move this patch after the patch adding the

[PATCH v2 07/18] dt-bindings: msm: dsi-controller-main: Add compatible strings for every current SoC

[Bryan O'Donoghue]

Currently we do not differentiate between the various users of the
qcom,mdss-dsi-ctrl. The driver is flexible enough to operate from one
compatible string but, the hardware does have some significant differences
in the number of clocks.

To facilitate documenting the clocks add the following compatible strings

- qcom,mdss-dsi-ctrl-apq8064
- qcom,mdss-dsi-ctrl-msm8916
- qcom,mdss-dsi-ctrl-msm8974
- qcom,mdss-dsi-ctrl-msm8996
- qcom,mdss-dsi-ctrl-sc7180
- qcom,mdss-dsi-ctrl-sc7280
- qcom,mdss-dsi-ctrl-sdm630
- qcom,mdss-dsi-ctrl-sdm660
- qcom,mdss-dsi-ctrl-sdm845
- qcom,mdss-dsi-ctrl-sm8250

Generic comment: I think we'd better follow the arm/qcom-soc.yaml and 
use qcom,soc-something as compat string. This would leave us with 
qcom,apq8064-dsi-ctrl

I'm not sure if we want to follow the qcm2290 approach and encode the 
DSI ctrl revision here (6g vs v2).

That's a requirement. Only existing patterns are allowed to continue,
but here all there is no such pattern.

For qcm2290 I'm thinking qcm2290-dsi-ctrl - without the 6g piece.

a) Nobody is using the compat at the moment
b) I'm not sure what - if any real information the silicon version
    number conveys here.

[PATCH v2 08/18] dt-bindings: msm: dsi-controller-main: Document clocks on a per compatible basis

[Bryan O'Donoghue]

Each compatible has a different set of clocks which are associated with it.
Add in the list of clocks for each compatible.

[PATCH v2 13/18] arm64: dts: qcom: sc7180: Add compat qcom,mdss-dsi-ctrl-sc7180

[Bryan O'Donoghue]

Add silicon specific compatible qcom,mdss-dsi-ctrl-sc7180 to the
mdss-dsi-ctrl block. This allows us to differentiate the specific bindings
for sc7180 against the yaml documentation.

This seems fine, but I don't think it matches your bindings. Your
bindings says you can have one compatible string. It could be
"qcom,mdss-dsi-ctrl-sc7180" or it could be "qcom,mdss-dsi-ctrl".
...but your device tree has two compatible strings: the SoC specific
one and the fallback one. You need to change your bindings to make
this work.

With the update in this series the binding has a required const.

If you drop back to just "qcom,mdss-dsi-ctrl-sc7180" you get a warning 
like this.

arch/arm64/boot/dts/qcom/sc7180-trogdor-homestar-r4.dtb: dsi@ae94000: 
compatible: ['qcom,mdss-dsi-ctrl-sc7180'] is too short

If you just have 'qcom,mdss-dsi-ctrl' you get

arch/arm64/boot/dts/qcom/sc7180-trogdor-homestar-r4.dtb: dsi@ae94000:

Huh. I must have missed something then. Ah, I see the problem. Since
you didn't CC me on the bindings change I searched myself. I found
patch #7 in your series ("dt-bindings: msm: dsi-controller-main: Add
compatible strings for every current SoC"). In that patch everything
is flat. I didn't notice patch #8 in your series which changes this. I
would just get the compatibles right the right time. Looking at patch
#8 I see that Dmitry already suggested this.

So that means this is fine with me. A slight nit that I suspect Bjorn
would prefer you to blow past the 80 column limit and put both
compatibles on one line, but it's not huge in my mind.
