Thanks Rob for reviews.
We are using Display Port Controller block to detect hot plug.
So we won't be using that pin as GPIO.
I found now that we don't need any bindings for that pin in such case.
So I am abandoning this patch series and upload new patch.
Thanks.

While we support using both tx slots for sideband transmissions, it
appears that DisplayPort devices in the field didn't end up doing a very
good job of supporting it. From section 5.2.1 of the DP 2.0
specification:
There are MST Sink/Branch devices in the field that do not handle

Because this patch will likely end up fixing a lot of MST issues we
either don't know about, or weren't able to figure out a fix for before,
I definitely want to make sure this patch gets cc'd to stable as well.
It doesn't apply cleanly to drm-misc-fixes, so here's a backported
version that does.

.yaml files can contain maintainer/author addresses and it seems
unlikely or unnecessary that individual MAINTAINER file section
entries for each .yaml file will be created.

According to the DSI Host Registers sections available in the IMX,
STM and RK ref manuals for 1.01, 1.30 and 1.31, the register fields
are smaller or bigger than what's coded in the driver, leading to
r/w in reserved spaces which might cause undefined behaviours.

Prepare the bridge driver for use in a chained setup by
replacing direct use of drm_panel with drm_panel_bridge support.
The bridge driver assume the panel is optional.
The relevant tests are migrated over to check for the

In order to support multiple versions of the Synopsis MIPI DSI host
controller, which have different register layouts but almost identical
HW protocols, we add a regmap infrastructure which can abstract away
register accesses for platform drivers using the bridge.

Hello everyone,
The dt-binding added in this series depends on [1] for
"make dt_binding_check" to pass.
The biggest change in v8 is a conversion of the imx6 host controller
driver to drm_bridge and an extension to dw_mipi_dsi.c which allows
platform drivers to daisy-chain bridges between the
All panels shall report a connector type.
panel-simple has a lot of panels with no connector_type,
and for these fall back to DPI as the default.

Somehow Laurent tricked me into updating a bridge driver.
In reality, having updated a driver yourself makes for much
better understanding of what is going on.
So in order to provide proper review feedback I deciced to give
it a spin.
Second iteration of this patchset covers several drivers,
and
The stm mipi-dsi platform driver added a version test in
commit fa6251a747b7 ("drm/stm: dsi: check hardware version")
so that HW revisions other than v1.3x get rejected. The rockchip
driver had no such check and just assumed register layouts are
v1.3x compatible.
Having such tests was a good idea
Register existence, address/offsets, field layouts, reserved bits and
so on differ between MIPI-DSI versions and between SoC vendor boards.
Despite these differences the hw IP and protocols are mostly the same
so the generic bridge can be made to compensate these differences.
The current Rockchip
The boe,hv070wsa-100 panel is a LVDS panel.
Fix connector type to reflect this.
With this change users of this panel do not have to specify the
connector type.
v2:
- Add .bus_format (Laurent)
- Add .bus_flags

'host1x_debug_init()' must be reverted in an error handling path.
This is already fixed in the remove function since commit 44156eee91ba

Convert the ingenic,intc.txt doc file to ingenic,intc.yaml.
Some compatible strings now require a fallback, as the controller
generally works the same across the SoCs families.
