Subject: [PATCH v2 2/2] arm64: dts: allwinner: a64-amarula-relic: Add OV5640 camera node
Date: Thu, 18 Apr 2019 19:22:32 +0530	[thread overview]
Message-ID: <20190418135232.9368-2-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20190418135232.9368-1-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

Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>
---
Changes for v2:
- use node name as i2c instead of i2c-csi
- drop i2c gpio pin documentation
- drop unneeded address, size properties
