Subject: [PATCH v5 3/4] ARM: dts: rockchip: Add VMARC RK3288 SOM initial support
Date: Thu, 9 Jul 2020 15:37:55 +0530 [thread overview]
Message-ID: <20200709100756.42384-4-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20200709100756.42384-1-jagan@amarulasolutions.com>
VMARC RK3288 SOM is a standard SMARC SOM design with
Rockchip RK3288 SoC, which is designed by Vamrs.
Specification:
- Rockchip RK3288
- PMIC: RK808
- eMMC: 16GB/32GB/64GB
- SD slot
- 2xUSB-2.0, 1xUSB3.0
- USB-C for power supply
- Ethernet
- HDMI, MIPI-DSI/CSI, eDP
Add initial support for VMARC RK3288 SOM, this would use
with associated carrier board.

Changes for v5, v4, v3:
- none
Changes for v2:
- drop pwm include
- adjust dtsi based on trivial changes in 1/4
