Subject: [PATCH 5/5] arm64: dts: allwinner: a64-amarula-relic: Add OV5640 camera node
Date: Mon,  3 Dec 2018 15:37:47 +0530	[thread overview]
Message-ID: <20181203100747.16442-6-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20181203100747.16442-1-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
- DLDO3 as vcc-csi supply
- DLDO3 as AVDD supply
- ALDO1 as DOVDD supply
- ELDO3 as DVDD supply
- PE14 gpio for reset pin
- PE15 gpio for powerdown pin
