Subject[PATCH 0/2] pmu0 MMIO region for A64 USB PHY
Message-ID<tsUgi-3Nd-7@gated-at.bofh.it>
The USB PHY of A64 contains a "pmu0" MMIO region, which contains some control
registers for the EHCI0/OHCI0 pair on A64 SoC.

This pair is not used currently in 4.11, but when enabling it in 4.12, the
MMIO region is needed.

In order to prevent device tree compatibility breakage, add this region in
4.11.

Icenowy Zheng (2):
  dt: bindings: add pmu0 regs for USB PHYs on Allwinner H3/V3s/A64
  arm64: allwinner: a64: add pmu0 regs for USB PHY

I feel the binding documentation can go along with the dt changes. Moreover I
have no plans of sending another pull request for this -rc cycle.

FWIW:
Acked-by: Kishon Vijay Abraham I <kishon@ti.com>

Thanks
