[0/7] sunxi: add the Allwinner B288 and the PocketBook Verse

The Allwinner B288 (sun8iw10p1) is a dual Cortex-A7 SoC used in e-book
readers. This series adds SPL and U-Boot support for it, and one board:
the PocketBook Verse (PB629).

The DT is still under review for Linux. Until it reaches
dts/upstream, the last patch carries a copy in arch/arm/dts.

Tested on a PB629.

Pablo Mazzini (7):
  sunxi: add support for the Allwinner B288
  sunxi: dram: support the Allwinner B288
  dt-bindings: clock: add the Allwinner B288 CCU
  clk: sunxi: add the Allwinner B288 gates and resets
  pinctrl: sunxi: add the Allwinner B288 PIO
  mmc: sunxi: B288 mmc0/mmc1 run off PLL_PERIPH0 2x
  sunxi: add the PocketBook Verse

Thanks for sending this, much appreciated. I had a coarse look over 
this, and this looks fine on the first glance.
As you said, this is somewhat blocked on the DT merge on the Linux side, 
which will probably not happen this year anymore (v7.5-rc1 would be the 
earliest).
But meanwhile, in preparation for that, could you please reorder the 
patches, so you enable the devices first (clocks, pinctrl, mmc), then 
DRAM, then the general support patch, with the defconfig on top.

For the DT parts: please try to emulate the future situation, so put the 
files in the directories where they would end up eventually. You can try 
to take the Linux DT binding patch (for clock and reset), and just 
change the paths in there to point to the respective dts/upstream 
directories. This is what would happen anyway, look for those 
cherry-picks and upstream references in the dts/upstream git log.
And the patch(es) wouldn't be taken as such anyway, but they provide a 
test base and reference for other people, until the DT lands.

There is no need to send a new version now, just wait until you receive 
some review or other comments.

Cheers,
Andre

Hi Andre,

Thanks for having a look. I'll reorder the patches and move the DT
bits to dts/upstream for v2, once there's more feedback.
