Hi, Dave & Daniel:
This includes:
1. Transfer display binding document to yaml format.
2. Add mt8195 display device binding.
3. Allow commands to be sent during video mode.
4. Add wait_for_event for crtc disable by cmdq.
Regards,
Chun-Kuang.

if they're accidentially ordered wrongly. It is still useful to keep

A specialisation of the generic Synopsys HDMI driver is employed for
JZ4780 HDMI support. This requires a new driver, plus device tree and
configuration modifications.
Here we add Kconfig DRM_INGENIC_DW_HDMI, Makefile and driver code.
Note that there is no hpd-gpio installed
so that specialization drivers like ingenic-dw-hdmi can enable polling.

Commit 7cd70656d1285b ("drm/bridge: display-connector: implement bus fmts
callbacks")
introduced a new mechanism to negotiate bus formats between hdmi connectors
and bridges which is to be used e.g. for the jz4780 based CI20 board.
In this case dw-hdmi sets up a list of formats in
"hdmi-connector.yaml" bindings defines an optional property
"ddc-en-gpios" for a single gpio to enable DDC operation.
Usually this controls +5V power on the HDMI connector.
This +5V may also be needed for HPD.
This was not reflected in code.
Now, the driver activates the ddc gpio after probe

I found a minor in the smtcfb_read() function of the driver sm712fb.
This read function can not handle the case that the size of the
buffer is 3 and does not check for it, which may cause a page fault.

Hi,
I found a minor in the smtcfb_write() function of the driver sm712fb.
This write function can not handle the case that the size of the
buffer is 3 and does not check for it, which may cause a page fault.

In file vega10_hwmgr.c, the names of struct vega10_power_state *
and struct pp_power_state * are confusingly used, which may lead
to some confusion.
Status quo is that variables of type struct vega10_power_state *
are named "vega10_ps", "ps", "vega10_power_state". A more
appropriate usage is that

This series:
1. Enables support of GuC to report error-state-capture
using a list of MMIO registers the driver registers
and GuC will dump, log and notify right before a GuC

2. Updates the ADS blob creation to register said lists
