Changes in this series add support for MSM display DSI CTRL & PHY drivers
for the SC7280 SoC, which has DSI controller v2.5.0 and DSI PHY v4.1.

This series also updates the missing bindings (yaml) for the 7nm DSI PHY
driver on "msm-next" branch.

The SC7280 SoC uses the 7nm (V4.1) DSI PHY driver with
different enable|disable regulator loads.

Judging from the next patch, you have one DSI host and one DSI PHY. 
Could you please correct io_start / num_dsi_phy here?

With these two issues fixed:

Thank you very much for your review :) I have incorporated the
review comments. I am waiting for comments on my DT bindings patch (1/3) 
and
will send v2 in a day or two.

Thanks,

These don't look like full SoC names (sm8150?) and it's

Thanks, Rob, for the review.

I just took the `compatible` property currently used in the DSI PHY 
driver
(drivers/gpu/drm/msm/dsi/phy/dsi_phy.c), and added a new entry for 
sc7280.
A similar pattern of `compatible` names are used in other variants of 
the
DSI PHY driver e.g. qcom,qcom,dsi-phy-10nm-8998, qcom,dsi-phy-14nm-660 
etc.

The existing compatible names "qcom,dsi-phy-7nm-8150" (SoC at the end) 
make
some sense, if we look at the organization of the dsi phy driver code.
I am new to this and don't know the reason behind the current code
organization and this naming.

Yes, I agree with you, we should use full SoC names. Adding
the SoC name at the end does not feel very convincing, so I will change 
this
to the suggested format e.g. "qcom,sm8250-dsi-phy-7nm", and will rename 
the
occurrences in the driver and device tree accordingly.
Do I need to make changes for 10nm, 14nm, 20nm, and 28nm DSI PHY too?
Bindings doc for these PHYs recently got merged to msm-next [1]

Hi Rob,

I missed adding "robh+dt@kernel.org" earlier in this thread.

Please check my response to your review comments. Regarding your 
suggestion to use <vendor>,<soc>-<block> format for compatible property, 
should I also upload a new patch to make changes in 10nm, 14nm, 20nm, 
and 28nm DSI PHY DT bindings?

Thanks,
Rajeev

Hi,

I missed this and ended up sending a similar patch a week later (as part 
of my cphy series, because I needed it to add a "phy-type" property).

"qcom,dsi-phy-7nm" and "qcom,dsi-phy-7nm-8150" aren't new compatibles, 
they were previously documented in the .txt bindings, which are getting 
removed, but the new .yaml bindings didn't include them. Documenting 
them is just a fixup to that patch [1] which is already R-B'd by RobH 
(and has similar compatibles such as "qcom,dsi-phy-10nm" and 
"qcom,dsi-phy-10nm-8998
").

You can use a different/better naming scheme for sc7280, but changing 
the others has nothing to do with adding support for sc7280.
