#1310995 — [PATCH 0/3] ARM: dts: sun8i: Add timer/watchdog for A83T and Cubietruck Plus

Hi Maxime,

This small series adds the timer/watchdog block for A83T, and also a new
board, the A83T/H8 based Cubietruck Plus from Cubietech.

Patch 1 from Vishnu adds the timer device node. This was picked from his
github branch sunxi-a83-wip.

Patch 2 adds the watchdog device node. We get watchdog and reboot support
on the A83T.

Patch 3 adds a basic DTS file for the Cubieteuck Plus.

#1310996 — [PATCH 2/3] ARM: dts: sun8i: Add watchdog device node for A83T

The A83T, like previous Allwinner SoCs, has a watchdog as part of its
timer block. Add a device node for it.

#1310997 — [PATCH 3/3] ARM: dts: sun8i: Add device tree for Cubietruck Plus

Cubietruck Plus is a A83T/H8 based development board. The board has
standard DDR3 SDRAM, AXP818 PMIC/codec, SD/MMC, eMMC, USB 2.0 host
via HSIC USB Hub, USB OTG, SATA via USB bridge, gigabit ethernet,
WiFi, headphone out / mic in, and various GPIO headers.

The board also has an EEPROM on i2c0 which holds the MAC address.

Time to use the nvmem framework then ;)
