Subject: [DO NOT MERGE] [PATCH v7 5/5] arm64: dts: allwinner: bananapi-m64: Add HDF5640 camera module
Date: Thu, 24 Jan 2019 23:37:36 +0530 [thread overview]
Message-ID: <20190124180736.28408-6-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190124180736.28408-1-jagan@amarulasolutions.com>
Bananapi M64 comes with an optional sensor based on the ov5640,
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
- DLDO3 as AVDD supply
- ALDO1 as DOVDD supply
- ELDO3 as DVDD supply
- PE16 gpio for reset pin
- PE17 gpio for powerdown pin
