mediatek/mt8173: Add support for Dual DSI output
The MT817x display output pipeline can be configured to drive an 8-lane MIPI/DSI panel using "dual DSI" mode. For the "dual DSI" video data path, the UFO block is configured to reorder the data stream into left and right halves which are then sent by the SPLIT1 block to the DSI0 and DSI1 respectively. The DSI0 and DSI1 outputs are then synchronously clocked at half the nominal data rate by their respective MIPI_TX0/MIPI_TX1 phys. Also, update the call sites in oak mainboard to avoid build breakage. BRANCH=none BUG=b:35774871 TEST=Boot Rowan in developer mode and see output on the panel Change-Id: Id47dfd7d9e98689b54398fc8d9142336b41dc29f Signed-off-by: Jitao Shi <jitao.shi@mediatek.com> Signed-off-by: Daniel Kurtz <djkurtz@chromium.org> Reviewed-on: https://review.coreboot.org/19361 Tested-by: build bot (Jenkins) Reviewed-by: Julius Werner <jwerner@chromium.org>
