This time I dropped the USB support from the basic series, to split off the discussion, and simplify the core SoC support. I will post the USB series soon, to be applied on top. I kept the RTC support in, even though this is still under discussion, because this is important to keep future DT files compatible with this kernel. This gains one fix patch for the existing RTC driver. For a complete changelog, see below. Based on 5.14-rc1. Let me know if you need a different base. Relies on this pinctrl fix: http://lists.infradead.org/pipermail/linux-arm-kernel/2021-July/672813.html Also available here: https://github.com/apritzel/linux/commits/h616-v8 Thanks! Andre ================== This series gathers patches to support the Allwinner H616 SoC. This is a rather uninspired SoC (Quad-A53 with the usual peripherals), but allows for some cheap development boards and TV boxes, and supports up to 4GB of DRAM. Some DT binding patches are sprinkled throughout the series, to add the new compatible names right before they are used. Patch 3-7 add support for the new RTC: the date is now stored as a linear number, not broken down into day-month-year. The benefit is that this lifts the limit of the old date counter, which would have rolled over around 2032. Also the alarm setting is using the same storage format as the current time, compared to the number of seconds left used in existing SoCs. Eventually we get the .dtsi for the SoC in patch 8, and the .dts for the OrangePi Zero2 board[1] in the penultimate patch, followed by the .dts for the X96 Mate TV box[2] in the final commit. U-Boot and Trusted Firmware support is now merged in released versions, it allows booting via FEL or SD card, also you can TFTP kernels in on the OrangePi Zero 2 board. Many thanks to Jernej for his tremendous help on this, also for the awesome input and help from the #linux-sunxi Freenode channel. The whole series (including the pinctrl fix) can also be found here: https://github.com/apritzel/linux/commits/h616-v8 Happy reviewing!
