This series adds the CCU and pin controller drivers, the RTC, I2C, NMI and watchdog 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. The pin controller relies on "pinctrl: sunxi: dt: number the IRQ banks from the first one that has IRQs" for correct PIO interrupt mapping. Changes since v2: - Drop the MMC binding patch, applied by Ulf. - Rebase onto sunxi/for-next. - Constrain the RTC clock outputs and pinctrl interrupts in the bindings (Sashiko). - Add a B288 watchdog compatible (Andre). - DTS: drop the memory node, the arch timer workaround and the sunxi.c entry; add disable-wp and the eMMC 1.8V modes; DLDO1 no longer always-on; mainline pin function names (Andre). 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.
