This patch add support for Bananapi S070WV20-CT16 DSI panel to BPI-M64 board. DSI panel connected via board DSI port with, - DLDO1 as VDD 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 | 43 +++++++++++++++++++ 1 file changed, 43 insertions(+)
