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.

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.

Various DT binding patches are sprinkled throughout the series, to add
the new compatible names right before they are used.
Patch 2 and 3 add clock support. For the -R clock this is shared with
the H6 code, as the clocks are identical, with the H616 just having
fewer of them. The main clocks are different enough to warrant a separate
file.
Patches 5 and 6 teach the AXP MFD driver to get along without having an
interrupt, as the missing NMI pin on the H616 leads to some boards not
having the AXP IRQ line connected.
Patch 8 and 14 add some tweaks to the syscon and EMAC driver, to deal
with the second EMAC clock used for the second Ethernet controller.
Patches 15 and 18 add USB support.

The remaining patches add DT bindings, which just add the new compatible
string along with an existing name as a fallback string.
Eventually we get the .dtsi for the SoC in patch 19, and the .dts for
the OrangePi Zero2 board[1] in the last patch.

We have U-Boot and Trusted-Firmware support in a working state, booting
via FEL or SD card and even TFTPing kernels work already [2][3].
The U-Boot patches are going to be merged this week.

Many thanks to Jernej for his tremendous help on this, also for the
awesome input and help from the #linux-sunxi Freenode channel.

Happy reviewing!

Cheers,
Andre
