[PATCH v2 0/3] drm/panel-edp: remove several legacy compatibles used by the driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There are two ways to describe an eDP panel in device tree. The
recommended way is to add a device on the AUX bus, ideally using the
edp-panel compatible. The legacy way is to define a top-level platform
device for the panel.

Document that adding support for eDP panels in a legacy way is strongly
discouraged (if not forbidden at all).

While we are at it, also drop legacy compatible strings and bindings for
five panels. These compatible strings were never used by a DT file
present in Linux kernel and most likely were never used with the
upstream Linux kernel.

The following compatibles were never used by the devices supported by
the upstream kernel and are a subject to possible removal:

- lg,lp097qx1-spa1
- samsung,lsn122dl01-c01
- sharp,ld-d5116z01b

I'm considering dropping them later, unless there is a good reason not
to do so.
