Warn if we detect a panel with incomplete/wrong description.
This is inspired by a similar patch by Laurent that introduced checks
for LVDS panels - this extends the checks to the remaining type of
connectors.
This is known to warn for some of the existing panels but added
despite this as we need help from people using the panels to
add the missing info.
The checks are not complete but will catch the most common mistakes.
The checks at the same time serve as documentation for the minimum
required description for a panel.
The checks uses dev_warn() as we know this will hit. WARN() was
too noisy at the moment for anything else than LVDS.

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.

The DRM panel bridge core requires connector type to be set up properly,

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

The NVIDIA Tegra DRM driver recently gained DRM bridges support for the

Hence all panels should have connector type set properly now, otherwise

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.

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().

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.

There are two variants of the COM37H3M panel.
The older one's COM37H3M05DTC data sheet specifies:
MIN TYP MAX
CLK frequency fCLK -- 22.4 26.3 MHz (in VGA mode)
VSYNC Frequency fVSYNC 54 60 66 Hz
VSYNC cycle time tv -- 650 -- H
HSYNC frequency fHSYNC -- 39.3 -- kHz
HSYNC cycle time th -- 570 -- CLK
The newer one's COM37H3M99DTC data sheet says:
MIN TYP MAX
CLK frequency fCLK 18 19.8 27 MHz
VSYNC Frequency fVSYNC 54 60 66 Hz
VSYNC cycle time tv 646 650 700 H
HSYNC frequency fHSYNC -- 39.0 50.0 kHz
HSYNC cycle time th 504 508 630 CLK
So we choose a parameter set that lies within the specs
of both variants. We start at .vrefresh = 60,
choose .htotal = 570 and .vtotal = 650 and end up
in a clock of 22.230 MHz.

The panel-dpi compatible is a fallback that
allows the DT to specify the timing.
When matching panel-dpi expect the device tree to include the
timing information for the display-panel.
Background for this change:
There are a lot of panels and new models hits the market very often.
It is a lost cause trying to chase them all and users of new panels
will often find them in situations that the panel they ues are not
supported by the kernel.
On top of this a lot of panels are customized based on customer
specifications.
Including the panel timing in the device tree allows for a simple
way to describe the actual HW and use this description in a generic
way in the kernel.
This allows uses of proprietary panels, or panels which are not
included in the kernel, to specify the timing in the device tree
together with all the other HW descriptions.
And thus, using the device tree it is then easy to add support
for an otherwise unknown panel.
The current support expect panels that do not require any
delays for prepare/enable/disable/unprepare.

With gcc -O3 in combination with the structleak plug, the compiler can
inline very aggressively, leading to rather large stack usage:
drivers/gpu/drm/panel/panel-tpo-td028ttec1.c: In function 'td028ttec1_prepare':
drivers/gpu/drm/panel/panel-tpo-td028ttec1.c:233:1: error: the frame size of 2768 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
}
Marking jbt_reg_write_*() as noinline avoids the case where
multiple instances of this function get inlined into the same
stack frame and each one adds a copy of 'tx_buf'.
The compiler is clearly making some bad decisions here, but I
did not open a new bug report as this only happens in combination
with the structleak plugin.
This fixes mmtom ("init/Kconfig: enable -O3 for all arches")

The panel drivers used drm_panel.drm for two purposes:
1) Argument to drm_mode_duplicate()
2) drm->dev was used in error messages
The first usage is replaced with drm_connector.dev
- drm_connector is already connected to a drm_device
and we have a valid connector
The second usage is replaced with drm_panel.dev
- this makes drivers more consistent in their dev argument
used for dev_err() and friends
With these replacements there are no more uses of drm_panel.drm,
so it is removed from struct drm_panel.
With this change drm_panel_attach() and drm_panel_detach()
no longer have any use as they are empty functions.
v2:
- editorial correction in changelog (Laurent)

Add a type field to the drm_panel structure to report the panel type,
using DRM_MODE_CONNECTOR_* macros (the values that make sense are LVDS,
eDP, DSI and DPI). This will be used to initialise the corresponding
connector type.
Update all panel drivers accordingly. The panel-simple driver only
specifies the type for the known to be LVDS panels, while all other
panels are left as unknown and will be converted on a case-by-case
basis as they all need to be carefully reviewed.

If the panel is wrapped in a panel_bridge it gets prepar()ed before the
upstream DSI bridge which can cause hangs (e.g. with imx-nwl since clocks
are not enabled yet). To avoid this move the panel's first DSI access to
enable() so the upstream bridge can prepare the DSI host controller in
it's pre_enable().
This is also in line with other panel drivers.

In the patch ("video: of: display_timing: Don't yell if no timing node

of_get_display_timing() if no node is present. Presumably panel-lvds
should take charge of spouting its own error now.
NOTE: we'll print two errors if the node was present but there were
problems parsing the timing node (one in of_parse_display_timing() and
this new one). Since this is a fatal error for the driver's probe
(and presumably someone will be debugging), this should be OK.

This attempts to address outstanding review feedback from
commit b8a2948fa2 ("drm/panel: simple: Add ability to override typical timing")
Specifically:
* It was requested that I document (in the structure definition) that
the device tree override had no effect if 'struct drm_display_mode'
was used in the panel description. I have provided full Doxygen
comments for 'struct panel_desc' to accomplish that.
* panel_simple_get_fixed_modes() was thought to be a confusing name,
so it has been renamed to panel_simple_get_display_modes().
* panel_simple_parse_override_mode() was thought to be better named as
panel_simple_parse_panel_timing_node().

The horizontal blanking periods are too short, as the values are
specified for a single LVDS channel. Since this panel is dual LVDS
they need to be doubled. With this change the panel reaches its
nominal vrefresh rate of 60Fps, instead of the 64Fps with the
current wrong blanking.
Philipp Zabel added:
The datasheet specifies 960 active clocks + 40/128/160 clocks blanking
on each of the two LVDS channels (min/typical/max), so doubled this is
now correct.

The AUO b101ean01's datasheet says:
* Vertical blanking min is 12
* Horizontal blanking min is 60
* Pixel clock is between 65.3 MHz and 75 MHz
The goal here is to be able to specify the proper timing in device
tree to use on rk3288-veyron-minnie to match what the downstream
kernel is using so that it can used the fixed PLL.

Convert the Innolux n116bge from using a fixed mode to specifying a
display timing with min/typ/max values.
Note that the n116bge's datasheet doesn't fit too well into DRM's way
of specifying things. Specifically the panel's datasheet just
specifies the vertical blanking period and horizontal blanking period
and doesn't break things out. For now we'll leave everything as a
fixed value but just allow adjusting the pixel clock. I've added a
comment on what the datasheet claims so someone could later expand
things to fit their needs if they wanted to test other blanking
periods.
The goal here is to be able to specify the panel timings in the device
tree for several rk3288 Chromebooks (like rk3288-veryon-jerry). These
Chromebooks have all been running in the downstream kernel with the
standard porches and sync lengths but just with a slightly slower
pixel clock because the 76.42 MHz clock is not achievable from the
fixed PLL that was available. These Chromebooks only achieve a
refresh rate of ~58 Hz. While it's probable that we could adjust the
timings to achieve 60 Hz it's probably wisest to match what's been
running on these devices all these years.
I'll note that though the upstream kernel has always tried to achieve
76.42 MHz, it has actually been running at 74.25 MHz also since the
video processor is parented off the same fixed PLL.

This patch adds the ability to override the typical display timing for a
given panel. This is useful for devices which have timing constraints
that do not apply across the entire display driver (eg: to avoid
crosstalk between panel and digitizer on certain laptops). The rules are
as follows:
- panel must not specify fixed mode (since the override mode will
either be the same as the fixed mode, or we'll be unable to
check the bounds of the overried)
- panel must specify at least one display_timing range which will be
used to ensure the override mode fits within its bounds
Changes in v2:
- Parse the full display-timings node (using the native-mode) (Rob)
Changes in v3:
- No longer parse display-timings subnode, use panel-timing (Rob)
Changes in v4:
- Don't add mode from timing if override was specified (Thierry)
- Add warning if timing and fixed mode was specified (Thierry)
- Don't add fixed mode if timing was specified (Thierry)
- Refactor/rename a bit to avoid extra indentation from "if" tests
- i should be unsigned (Thierry)
- Add annoying WARN_ONs for some cases (Thierry)
- Simplify 'No display_timing found' handling (Thierry)
- Rename to panel_simple_parse_override_mode() (Thierry)

Move mipi_dsi_dcs_set_display_off() from innolux_panel_disable()
to innolux_panel_unprepare(), so they are consistent with
innolux_panel_enable() and innolux_panel_prepare().
This also fixes some mode check and irq timeout issue in MTK dsi code.
Since some dsi code (e.g. mtk_dsi) have following call trace:
1. drm_panel_disable(), which calls innolux_panel_disable()
2. switch to cmd mode
3. drm_panel_unprepare(), which calls innolux_panel_unprepare()
However, mtk_dsi needs to be in cmd mode to be able to send commands
(e.g. mipi_dsi_dcs_set_display_off() and mipi_dsi_dcs_enter_sleep_mode()),
so we need these functions to be called after the switch to cmd mode happens,

The TPO (Toppoly) TPG110 is a pretty generic display driver
similar in vein to the Ilitek 93xx devices. It is not a panel
per se but a driver used with several low-cost noname panels.
This is used on the Nomadik NHK15 combined with a OSD
OSD057VA01CT display for WVGA 800x480.
The driver is pretty minimalistic right now but can be
extended to handle non-default polarities, gamma correction
etc.
The driver is based on the baked-in code in
drivers/video/fbdev/amba-clcd-nomadik.c which will be
decomissioned once this us upstream.

Having failed any attempts at a more generic solution,
I fall back to the very specific solution: define a simple
panel for the ARM RTSM emulated platforms.
I am doing this so we can convert all old users from the
previous fbdev driver to the PL111 DRM driver.
This works fine as far as I can test, provided the
device tree for RTSM AEMv8 is augmented accordingly.

As far as I can tell the panel that was added in commit da50bd4258
("drm/panel: simple: Add Innolux TV123WAM panel driver support")
wasn't actually an Innolux TV123WAM but was actually an Innolux
P120ZDG-BF1.
As far as I can tell the Innolux TV123WAM isn't a real panel and but
it's a mosh between the TI TV123WAM and the Innolux P120ZDG-BF1.
Let's unmosh.
Here's my evidence:
* Searching for TV123WAM on the Internet turns up a TI panel. While
it's possible that an Innolux panel has the same model number as the
TI Panel, it seems a little doubtful. Looking up the datasheet from
the TI Panel shows that it's 1920 x 1280 and 259.2 mm x 172.8 mm.
* As far as I know, the patch adding the Innolux Panel was supposed to
be for the board that's sitting in front of me as I type this
(support for that board is not yet upstream). On the back of that
panel I see Innolux P120ZDZ-EZ1 rev B1.
* Someone pointed me at a datasheet that's supposed to be for the
panel in front of me (sorry, I can't share the datasheet). That
datasheet has the string "p120zdg-bf1"
* If I search for "P120ZDG-BF1" on the Internet I get hits for panels
that are 2160x1440. They don't have datasheets, but the fact that
the resolution matches is a good sign.
In any case, let's update the name and also the physical size to match
the correct panel.

If the HPD signal isn't hooked up to this panel we need a 200 ms
delay. In the datasheet this is shown as the maximum time that HPD
will take to be asserted after power is given to the panel.

Some eDP panels that are designed to be always connected to a board
use their HPD signal to signal that they've finished powering on and
they're ready to be talked to.
However, for various reasons it's possible that the HPD signal from
the panel isn't actually hooked up. In the case where the HPD isn't
hooked up you can look at the timing diagram on the panel datasheet
and insert a delay for the maximum amount of time that the HPD might
take to come up.
Let's add support in simple-panel for this concept.
At the moment we will co-opt the existing "prepare" delay to keep
track of the delay and we'll use a boolean to specify that a given
panel should only apply the delay if the "no-hpd" property was
specified.

This patch adds Olimex Ltd. LCD-OLinuXino bridge panel driver. The panel

small EEPROM chip is used for identification, which holds some factory

This panel is marketed as Banana Pi 7" LCD display. On the back is
a sticker denoting the model name S070WV20-CT16.
This is a 7" 800x480 panel connected through a 24-bit RGB interface.
However the panel only does 262k colors.
Depending on the variant, the PCB attached to the panel module either
supports DSI, or DSI + 24-bit RGB. DSI is converted to 24-bit RGB via
an onboard ICN6211 MIPI DSI - RGB bridge chip, then fed to the panel
itself.
