This patch add support for Bananapi S070WV20-CT16 DSI panel to BPI-M64 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, - DLDO1 as VCC-DSI supply - PD6 gpio for reset pin - PD5 gpio for backlight enable pin - PD7 gpio for backlight vdd supply Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> --- .../dts/allwinner/sun50i-a64-bananapi-m64.dts | 63 +++++++++++++++++++ 1 file changed, 63 insertions(+)
