Subject: [PATCH v3 6/6] arm64: dts: allwinner: a64-amarula-relic: Add OV5640 camera node
Date: Mon, 10 Dec 2018 17:22:46 +0530 [thread overview]
Message-ID: <20181210115246.8188-7-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20181210115246.8188-1-jagan@amarulasolutions.com>
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
