Subject[PATCH v11 0/6] arm64: sunxi: Initial Allwinner H616 SoC support
Date
Hi,

another attempt in getting the H616 finally officially supported. The
RTC patches went in, and together with the new RTC clock driver this
part is *mostly* covered now. The first two patches plug the last two
holes in the clock tree: the new RTC register gate clock, and the PLL
derived 32KHz clock, both required by the new RTC clock binding. Now
also working on the H6 ;-)
For simplicity I dropped the USB patches again - for now.

This is based on top of 5.18-rc3, but requires the "mark rtc-32k as
critical" clock patch[1], which has been pushed, but didn't reach
Linus' tree yet. Please note that there is no conflict, it's "just"
required for functionality.

For a complete changelog, see below.

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.
Eventually we get the .dtsi for the SoC in patch 3, and the .dts for
the OrangePi Zero2 board[2] in the over-next patch, followed by the
.dts for the X96 Mate TV box[3] afterwards.

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 prerequisites) can also be found here:

Happy reviewing!

Cheers,
Andre
