drm/panel-simple: Support hpd-gpios for delaying prepare()

2020-05-09T20:11:45+00:00

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().

panel: simple: Add BOE NV133FHM-N62

2020-05-09T19:57:50+00:00

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.

panel: simple: Fix size and bpp of BOE NV133FHM-N61

2020-05-09T19:57:02+00:00

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.

drivers: drm: panel: Add ASUS TM5P5 NT35596 panel driver

2020-05-07T19:54:06+00:00

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.
