[PATCH v2 00/11] ARM: sunxi: add Allwinner B288 and the PocketBook Verse

[PATCH v2 00/11] ARM: sunxi: add Allwinner B288 and the PocketBook Verse

[Pablo Mazzini]

The Allwinner B288 (sun8iw10p1) is a dual Cortex-A7 SoC used in e-book
readers. This series adds the CCU and pin controller drivers, the RTC,
I2C, MMC and NMI compatibles, the SoC .dtsi, and one board: the
PocketBook Verse (PB629), a 6" reader.

The B288 is closest to the A64: most of its PLLs are bit-identical.
The clock and pin descriptions come from Allwinner's BSP, cross-checked
against ccu-sun50i-a64.c. Tested on a PB629, boots to userspace.

Changes since v1:
  - Add this cover letter.
  - Drop both new bindings; add the compatibles to the existing
    allwinner,sun4i-a10-{ccu,pinctrl}.yaml instead.
  - Rewrite the pinctrl driver in the DT-provided pinmux style.
