5d344b3089 drm/panel: simple: Add missing Innolux G121X1-L03 format, flags, connector 
[ Upstream commit 11ac72d033b9f577e8ba0c7a41d1c312bb232593 ]

The .bpc = 6 implies .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG ,
add the missing bus_format. Add missing connector type and bus_flags
as well.

Documentation [1] 1.4 GENERAL SPECIFICATI0NS indicates this panel is
capable of both RGB 18bit/24bit panel, the current configuration uses
18bit mode, .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , .bpc = 6.

Support for the 24bit mode would require another entry in panel-simple
with .bus_format = MEDIA_BUS_FMT_RGB666_1X7X4_SPWG and .bpc = 8, which
is out of scope of this fix.

939352ad65 drm/panel: simple: Fix Innolux G101ICE-L01 timings 
[ Upstream commit 3f9a91b6c00e655d27bd785dcda1742dbdc31bda ]

The Innolux G101ICE-L01 datasheet [1] page 17 table
6.1 INPUT SIGNAL TIMING SPECIFICATIONS
indicates that maximum vertical blanking time is 40 lines.
Currently the driver uses 29 lines.

Fix it, and since this panel is a DE panel, adjust the timings
to make them less hostile to controllers which cannot do 1 px
HSA/VSA, distribute the delays evenly between all three parts.

c8d0d3811e drm/panel: simple: Fix AUO G121EAN01 panel timings according to the docs 
[ Upstream commit e8470c0a7bcaa82f78ad34282d662dd7bd9630c2 ]

Commit 03e909acd9 ("drm/panel: simple: Add support for AUO G121EAN01.4
panel") added support for this panel model, but the timings it implements
are very different from what the datasheet describes. I checked both the
G121EAN01.0 datasheet from [0] and the G121EAN01.4 one from [1] and they
all have the same timings: for example the LVDS clock typical value is 74.4
MHz, not 66.7 MHz as implemented.

Replace the timings with the ones from the documentation. These timings
have been tested and the clock frequencies verified with an oscilloscope to
ensure they are correct.

Also use struct display_timing instead of struct drm_display_mode in order
to also specify the minimum and maximum values.

2) FRC=High ..... MEDIA_BUS_FMT_RGB888_1X7X4_SPWG ... BPP=8

Currently the panel description mixes both, BPP from 1) and bus
format from 2), which triggers a warning at panel-simple.c:615.

Pick the later, set bpp=8, fix the warning.

ddb8e853dc drm/panel: panel-simple: validate panel description 
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.

667d73d72f drm: panel: simple: Delay HPD checking on boe_nv133fhm_n61 for 15 ms 
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.

94f07917eb drm/panel-simple: Add missing connector type for some panels 
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:
