Allwinner R329 is a SoC targeting smart audio devices, with integrated
128M or 256M DRAM.

This patchset adds initial support for it, including pinctrl, rtc
(for rtc ccu), clocks and mmc. These makes a system booting.

The demo board for this support is Sipeed MaixSense (based on Sipeed
MIIA SoM).

Icenowy Zheng (12):
  dt-bindings: pinctrl: document Allwinner R329 PIO and R-PIO
  pinctrl: sunxi: add support for R329 CPUX pin controller
  pinctrl: sunxi: add support for R329 R-PIO pin controller
  rtc: sun6i: add support for R329 RTC
  dt-bindings: clock: sunxi-ng: add bindings for R329 CCUs
  clk: sunxi=ng: add support for R329 CCUs
  dt-bindings: mmc: sunxi-mmc: add R329 MMC compatible string
  mmc: sunxi: add support for R329 MMC controllers
  dt-bindings: arm: sunxi: add compatible strings for Sipeed MaixSense
  arm64: allwinner: dts: add DTSI file for R329 SoC
  arm64: allwinner: dts: r329: add DTSI file for Sipeed Maix IIA
  arm64: allwinner: dts: r329: add support for Sipeed MaixSense
