Subject: [PATCH v2 0/3] drm/panel: simple: add bus-format support for panel-dpi

Commit 4a1d0dbc8332 ("drm/panel: simple: add panel-dpi support") added
support for defining a panel from device tree provided data.

However support for setting the bus format is missing, so that with
the current implementation a 'panel-dpi' panel can only be used
if the driver of the display interface connected can cope with a
missing bus_format.

This patch series defines the new property bus-format and adds it to
the panel-dpi implementation.

Check initial discussions [1] and [2].
