The edp bridge dts fragment files use the macros defined in
'dt-bindings/gpio/gpio.h'.

To help us more flexibly order the #include lines of dts files in a
board-revision-specific dts file, let's include the gpio header in the
bridge dts fragment files themselves.

MSM DSI host driver actually parses "data-lanes" in DT and compare
it with the number of DSI lanes the bridge driver sets for
mipi_dsi_device. So we need to always specify "data-lanes" for the
DSI host output. As of now, "data-lanes" is added to ti-sn65dsi86 dts
fragment, but missing in parade-ps8640 dts fragment, which requires
a fixup.

Since we'll do 4-lane DSI regardless of which bridge chip is used,
instead of adding "data-lanes" to parade-ps8640 dts fragment, let's
just move "data-lanes" from the bridge dts to sc7180-trogdor.dtsi.

Support Lazor/Limozeen rev9 board where Parade ps8640 is added as the
second source edp bridge.

To support different edp bridge chips in different board revisions,
now we move the #incldue line of the edp bridge dts fragment (e.g.
sc7180-trogdor-ti-sn65dsi86.dtsi) from "sc7180-trogdor-lazor.dtsi" to
per-board-rev dts files.

Since the edp bridge dts fragment overrides 'dsi0_out', which is
defined in "sc7180.dtsi", move the #incldue line of "sc7180.dtsi" from
"sc7180-trogdor-lazor.dtsi" to per-board-rev dts files too, before
the #include line of the edp bridge dts fragment.

Retroactively edit the v2 change log slightly

(no changes since v2)

Changes in v2:
- Explain why "sc7180.dtsi" is moved out of "sc7180-trogdor-lazor.dtsi"
  in the commit message.
- In limozeen (nots) r5 dts, replace "google,rev5-sku5" with
  "google,lazor-rev5-sku5" and sort it
- In limozeen (nots) r9 dts, drop the support for "sku5".
- In limozeen r4 dts, remove the redundant "google,lazor-rev6-sku4" and
  add "google,lazor-rev7-sku4".
- Do not add panel compatible in -r9 dts files.
- Move the #include line of gpio.h from sc7180.dtsi to the bridge dts
  fragments, and factor out this change to patch 1/3.

Support Homestar rev4 board where Parade ps8640 is added as the
second source edp bridge.

Support different edp bridge chips in different board revisions,
now we move the #incldue line of the edp bridge dts fragment (e.g.
sc7180-trogdor-ti-sn65dsi86.dtsi) from "sc7180-trogdor-homestar.dtsi"
to per-board-rev dts files.

Since the edp bridge dts fragment overrides 'dsi0_out', which is
defined in "sc7180.dtsi", move the #incldue line of "sc7180.dtsi" from
"sc7180-trogdor-homestar.dtsi" to per-board-rev dts files too, before
the #include line of the edp bridge dts fragment.

I don't see data-lanes required in the schema, and
dsi_host_parse_lane_data() seems happy to continue without it. I do see
that num_data_lanes isn't set though. Does this patch fix it?

The problem I see is from dsi_host_attach().
If there is no "data-lanes" in DT, num_data_lanes would be 0.
Then dsi_host_attach() would return -EINVAL.

I haven't tried.
But I think it can fix the problem I described above.
Would you like to send it as a separate patch?
Or I can do it.

Sure feel free to send it as another patch. Or fix the schema to make
data-lanes required. I think fixing the driver is probably better so
that we don't have to set data-lanes when it's the default 4 lanes. At
least I think 4 lanes is the default.

Thanks!
For the other folks: the fix I posted for dsi_host is here:
https://patchwork.kernel.org/project/linux-arm-msm/patch/20211030100812.1.I6cd9af36b723fed277d34539d3b2ba4ca233ad2d@changeid/
