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.
