Subject: [RESEND 6/6 v2] drm/vc4: dpi: Support DPI interface in mode3 for RGB565
Date: Thu, 19 May 2022 11:29:35 -0500 [thread overview]
Message-ID: <20220519162935.1585-7-macroalpha82@gmail.com> (raw)
In-Reply-To: <20220519162935.1585-1-macroalpha82@gmail.com>
From: Chris Morgan <macromorgan@hotmail.com>
Add support for the VC4 DPI driver to utilize DPI mode 3. This is
defined here as xxxRRRRRxxGGGGGGxxxBBBBB:
https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#parallel-display-interface-dpi
This mode is required to use the Geekworm MZP280 DPI display.
