Subject: [PATCH] powerpc: dtc: update P2020RDB dts
P2020RDB contains multiple peripherals, which isn't added to
devicetree:
- Switch: Microchip VSC7385
- PMIC: Renesas ZL2006
- Temperature sensor: Analog Devices ADT7461
- Two eeproms: 24C256 and 24C01
- GPIO expander: NXP PCA9557
- reset gpios of Ethernet PHYs
This commit adds it.
Some refreshments was done:
- fixed link in ethernet-node
- platform drivers nodes names
- added 'gpio0' label in pq3-gpio-0.dtsi
