Pull drm updates from Dave Airlie:
"New xilinx displayport driver, AMD support for two new GPUs (more
header files), i915 initial support for RocketLake and some work on
their DG1 (discrete chip).
The core also grew some lockdep annotations to try and constrain what
drivers do with dma-fences, and added some documentation on why the
idea of indefinite fences doesn't work.
The long list is below.

On boe_nv133fhm_n62 (and presumably on boe_nv133fhm_n61) a scope shows
a small spike on the HPD line right when you power the panel on. The
picture looks something like this:
+--------------------------------------
|
|
|
Power ---+
+---
|
++ |
+----+| |
HPD -----+ +---------------------------+
So right when power is applied there's a little bump in HPD and then
there's small spike right before it goes low. The total time of the
little bump plus the spike was measured on one panel as being 8 ms
long. The total time for the HPD to go high on the same panel was
51.2 ms, though the datasheet only promises it is < 200 ms.
When asked about this glitch, BOE indicated that it was expected and
persisted until the TCON has been initialized.
If this was a real hotpluggable DP panel then this wouldn't matter a
whole lot. We'd debounce the HPD signal for a really long time and so
the little blip wouldn't hurt. However, this is not a hotpluggable DP
panel and the the debouncing logic isn't needed and just shows down
the time needed to get the display working. This is why the code in
panel_simple_prepare() doesn't do debouncing and just waits for HPD to
go high once. Unfortunately if we get unlucky and happen to poll the
HPD line right at the spike we can try talking to the panel before
it's ready.
Let's handle this situation by putting in a 15 ms prepare delay and
decreasing the "hpd absent delay" by 15 ms. That means:
* If you don't have HPD hooked up at all you've still got the
hardcoded 200 ms delay.
* If you've got HPD hooked up you will always wait at least 15 ms
before checking HPD. The only case where this could be bad is if
the panel is sharing a voltage rail with something else in the
system and was already turned on long before the panel came up. In
such a case we'll be delaying 15 ms for no reason, but it's not a
huge delay and I don't see any other good solution to handle that
case.
Even though the delay was measured as 8 ms, 15 ms was chosen to give a
bit of margin.

A few of the new panels create a local macro wrapping around
mipi_dsi_dcs_write. At the same time, they don't really care about the
command/payload split.
mipi_dsi_dcs_write does a kmalloc/memcpy/kfree for payload > 7 bytes.
Avoid that all together by using the _buffer function.
Aside:
panel-xinpeng-xpp055c272.c calls its wrapper "generic" although it
should be "dcs". But that for another day/patch.

The DRM panel bridge core requires connector type to be set up properly,
otherwise it rejects the panel. The missing connector type problem popped
up while I was trying to wrap CLAA070WP03XG panel into a DRM bridge in
order to test whether panel's rotation property work properly using
panel-simple driver on NVIDIA Tegra30 Nexus 7 tablet device, which uses
CLAA070WP03XG display panel.
The NVIDIA Tegra DRM driver recently gained DRM bridges support for the
RGB output and now driver wraps directly-connected panels into DRM bridge.
Hence all panels should have connector type set properly now, otherwise
the panel's wrapping fails.
This patch adds missing connector types for the LVDS panels that are found
on NVIDIA Tegra devices:
1. AUO B101AW03
2. Chunghwa CLAA070WP03XG
3. Chunghwa CLAA101WA01A
4. Chunghwa CLAA101WB01
5. EDT ET057090DHU
6. Innolux N156BGE L21
7. Samsung LTN101NT05

This patch adds support for Kaohsiung Opto-Electronics Inc.
10.1" TX26D202VM0BWA WUXGA(1920x1200) TFT LCD panel with LVDS interface.
The panel has dual LVDS channels.
My panel is manufactured by US Micro Products(USMP). There is a tag at
the back of the panel, which indicates the panel type is 'TX26D202VM0BWA'
and it's made by KOE in Taiwan.
The panel spec from USMP can be found at:
https://www.usmicroproducts.com/sites/default/files/datasheets/USMP-T101-192120NDU-A0.pdf
The below panel spec from KOE is basically the same to the one from USMP.
However, the panel type 'TX26D202VM0BAA' is a little bit different.
It looks that the two types of panel are compatible with each other.

None of the DSI panels set the connector_type in their panel_desc
descriptor. As they are all guaranteed to be DSI panels, that's an easy
fix, set the connector type to DRM_MODE_CONNECTOR_DSI.

People use panel-simple when they have panels that are builtin to
their device. In these cases the HPD (Hot Plug Detect) signal isn't
really used for hotplugging devices but instead is used for power
sequencing. Panel timing diagrams (especially for eDP panels) usually
have the HPD signal in them and it acts as an indicator that the panel
is ready for us to talk to it.
Sometimes the HPD signal is hooked up to a normal GPIO on a system.
In this case we need to poll it in the correct place to know that the
panel is ready for us. In some system designs the right place for
this is panel-simple.
When adding this support, we'll account for the case that there might
be a circular dependency between panel-simple and the provider of the
GPIO. The case this was designed for was for the "ti-sn65dsi86"
bridge chip. If HPD is hooked up to one of the GPIOs provided by the
bridge chip then in our probe function we'll always get back
-EPROBE_DEFER. Let's handle this by allowing this GPIO to show up
late if we saw -EPROBE_DEFER during probe. NOTE: since the
gpio_get_optional() is used, if the "hpd-gpios" isn't there our
variable will just be NULL and we won't do anything in prepare().

All info I could find about this panel show that it behaves the same
as the BOE NV133FHM-N61. However, it definitely appears to be a
unique panel because reading the EDID shows "NV133FHM-N62". We'll add
a string match for the new panel but until we find something unique
about it we'll just point at the N61's structures.

The BOE NV133FHM-N61 is documented in the original commit to be a
13.3" panel, but the size listed in our struct doesn't match.
Specifically:
math.sqrt(30.0 * 30.0 + 18.7 * 18.7) / 2.54 ==> 13.92
Searching around on the Internet shows that the size that was in the
structure was the "Outline Size", not the "Display Area". Let's fix
it.
Also the Internet says that this panel supports 262K colors. That's
6bpp, not 8bpp.

This adds support for TMP5P5 NT35596 1080x1920 video
mode panel that can be found on some Asus Zenfone 2
Laser (Z00T) devices.
This panel seems to only be found in this device
and we have no straightforward way of actually
getting the correct model number, as no schematics
are released publicly.
