Subject: [RFC PATCH 00/12] Support for Allwinner V831 SoC

Allwinner V831 is a new SoC by Allwinner oriented at the camera market.
It has a QFN88 package with co-packaged 64MiB DDR2 DRAM. Another SoC,
V833, is also available, which has the same die with V831 but w/o
co-packaged DRAM (thus a BGA package).

This patchset tries to add basical support for V831, with consideration
of V833 in many drivers.

The DT is only for a temporary test device w/o schematics, development
will be shifted to another device when the patchset leaves RFC.

Icenowy Zheng (12):
  dt-bindings: clock: sunxi-ng: add compatible for V831/V833 CCU
  dt-bindings: clk: sunxi-ng: add V833 CCU clock/reset indices headers
  clk: sunxi-ng: add CCU driver for V831/V833
  dt-bindings: pinctrl: sunxi: add compatible for V831/V833 pinctrl
  pinctrl: sunxi: add pinctrl driver for V831/V833
  dt-bindings: rtc: sun6i: add compatible string for V831/V833 RTC
  rtc: sun6i: add compatible string for V831/V833 RTC
  dt-bindings: mmc: sunxi: add compatible strings for V831 MMC
  dt-bindings: watchdog: sunxi: add compatible string for V831/V833 WDT
  dt-bindings: spi: sun6i: add compatible for V831 SPI
  ARM: dts: sun8i: add DTSI file for V831
  [DO NOT MERGE] ARM: dts: sun8i: v831: add a device tree file for Y20GA
