[PATCH v2 1/3] ARM: dts: rockchip: Add support for phyCORE-RK3288 SoM

From: Wadim Egorov
Date: Thu Apr 06 2017 - 09:05:03 EST

The phyCORE-RK3288 is a SoM (System on Module) containing a RK3288 SoC.
The module can be connected to different carrier boards.
It can be also equipped with different RAM, SPI flash and eMMC variants.
The Rapid Development Kit option is using the following setup:

- 1 GB DDR3 RAM (2 Banks)
- 1x 4 KB EEPROM
- DP83867 Gigabit Ethernet PHY
- 16 MB SPI Flash
- 4 GB eMMC Flash

Signed-off-by: Wadim Egorov <w.egorov@xxxxxxxxx>
---
Changes in v2:
- Added a dual license which is used for all rk3288 based boards.

Include minor changes from Heiko Stübner:
- moved phy-handle property up a bit
- switches compatible and #address+#size-cells in mdio0
- dropped rockchip,grf from &io_domains (grf is a simple-mfd and can
get the grf syscon on its own via its parent)
- vdd_cpu: regulator@60 (from fan53555@60)
- serial_flash: flash@0 (from m25p80@0)
Nodes should be named after their "category" not the actual device
