This patch add support for Bananapi S070WV20-CT16 panel to BPI-M2M board. Bananapi S070WV20-CT16 is a pure RGB output panel with ICN6211 DSI/RGB convertor bridge, so enable bridge along with associated panel. DSI panel connected via board DSI port with, - DCDC1 as VCC-DSI supply - PL5 gpio for bridge reset gpio pin - PB7 gpio for lcd enable gpio pin - PL4 gpio for backlight enable pin Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> --- Changes for v3: - none arch/arm/boot/dts/sun8i-r16-bananapi-m2m.dts | 85 ++++++++++++++++++++ 1 file changed, 85 insertions(+)
