Amarula A64-Relic board by default bound with OV5640 camera, so add support for it with below pin information. - PE13, PE12 via i2c-gpio bitbanging - CLK_CSI_MCLK as external clock - PE1 as external clock pin muxing - ALDO1 as AVDD supply - DLDO3 as DOVDD supply - ELDO3 as DVDD supply - PE14 gpio for reset pin - PE15 gpio for powerdown pin Signed-off-by: Jagan Teki <jagan@amarulasolutions.com> --- .../allwinner/sun50i-a64-amarula-relic.dts | 53 +++++++++++++++++++ 1 file changed, 53 insertions(+)
