drm/panel: simple: Fix AUO G121EAN01 panel timings according to the docs

2023-08-14T12:50:47+00:00

Commit 03e909acd95a ("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.

drm/panel: JDI LT070ME05000 simplify with dev_err_probe()

2023-08-14T12:48:49+00:00

Use the dev_err_probe() helper to simplify error handling during probe.
This also handle scenario, when EDEFER is returned and useless error is printed.

Fixes error:

drm/panel: samsung-s6d7aa0: Add MODULE_DEVICE_TABLE

2023-08-02T08:56:50+00:00

The driver can be built as a module, however the lack of the
MODULE_DEVICE_TABLE macro prevents it from being automatically probed
from the DT in such case.

Add the missed macro to make sure the module can load automatically.

Because the setting of hporch is too small, there will be warning in
kernel log[1]. After fine tune the HFP and HBP, this warning can be
solved. The actual measurement frame rate is 60.1Hz.

The Starry-ili9882 is a 10.51" WUXGA TFT panel. which fits in nicely with
the existing panel-boe-tv101wum-nl6 driver. From the datasheet,MIPI need
to keep the LP11 state before the lcm_reset pin is pulled high. So add
lp11_before_reset flag.
