Subject: [PATCH v10 2/2] drm/sun4i: sun6i_mipi_dsi: Support DSI GENERIC_SHORT_WRITE_2 transfer
Date: Mon, 13 May 2019 00:11:27 +0530 [thread overview]
Message-ID: <20190512184128.13720-3-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190512184128.13720-1-jagan@amarulasolutions.com>
Some DSI panels do use GENERIC_SHORT_WRITE_2 transfer protocol to host
DSI driver and which is similar to GENERIC_SHORT_WRITE.
Add support for the same transfer, so-that so-that the panels which are
requesting similar transfer type will process properly.
