Hi,

an update from the v3 last week, to add support for the Allwinner H616
SoC. Still based on the (updated) sunxi/for-next branch.
I am omitting the MMC and pinctrl patches now, as they have been taken
by Ulf and LinusW already into their trees.

I addressed the comments from the list, though not sure if the HOSC clock
coming from the RTC is really a good idea (didn't change it).

I was hoping that at least the clock and AXP patches (01/21-06/21) could
make it into 5.12 still? That would allow booting boards from SD card.
I am happy to strip the .dtsi and .dts patch to only contain the devices
that we actually support then, if needed.

For the changes: I split the joint DT bindings patch into subsystem
specific ones, hopefully this simplifies merging. There is a new fix
for the axp20x-pek driver, and the AXP IRQ fix has been amended as well
(according to Samuel's comments).

I eventually got USB to work, by requiring PHY 2 for [EO]HCI 1 & 3 as well.
Not sure this is the right fix, it might be just one clock or reset
line from that PHY that is needed for the others as well. Will do further
experiments.

For a more detailed changelog, see below.

The last one is not related to your changes, but the rest must be fixed
