Subject: [PATCH 1/2] drm/pl111: Deprecate the pads from the DT binding
Date: Wed, 24 Jul 2019 15:49:58 +0200	[thread overview]
Message-ID: <20190724134959.2365-1-linus.walleij@linaro.org> (raw)

The pads were an earlier workaround for the internal image
pipeline in the Linux fbdev subsystem. As we move to generic
definition of display properties and drivers that no longer
need this to work, deprecate this property.
