[v5,02/11] usb: musb: sunxi: add support for the F1C100s MUSB controller

From: Icenowy Zheng <uwu@icenowy.me>

The suniv SoC has a MUSB controller like the one in A33, but with a SRAM
region to be claimed.

Add support for it.

is there any chance you could take this patch (and the next one,
ideally) through your tree? And not sure if the binding patch (01/11)
should also go this way?
Patch 03/11 is a cleanup, so is somewhat optional, but Jernej acked
that recently.

The original series [1] is now almost three years old, and the whole
series was mostly ready in the previous cycle already, but got stuck
in some dependency chain, which should now be solved, since the PHY
patch series [2] made it into -next more than two weeks ago.

This would help to unblock the rest of this series, which are DT
patches only.

Many thanks, and let me know if there is something left for me to do.

Cheers,
Andre
