As discussed in the patch ("dt-bindings: drm/panel-simple: Introduce
generic eDP panels") we can actually support probing eDP panels at
runtime instead of hardcoding what panel is connected. Add support to
the panel-edp driver for this.
We'll implement a solution like this:
* We'll read in two delays from the device tree that are used for
powering up the panel the initial time (to read the EDID).
* In the EDID we can find a 32-bit ID that identifies what panel we've
found. From this ID we can look up the full set of delays.
After this change we'll still need to add per-panel delays into the
panel-simple driver but we will no longer need to specify exactly
which panel is connected to which board in the device tree. Nicely,
any panels that are only supported this way also don't need to
hardcode mode data since it's guaranteed that we can get that through
the EDID.
This patch will seed the ID-to-delay table with a few panels that I
have access to, many of which are on sc7180-trogdor devices.
