[PATCH 1/3] phy: sun4i-usb: enable PHY0 dual route switching for A64 USB PHY

[Icenowy Zheng]

Allwinner A64 SoC features a switchable PHY0 like the one in H3, which
can switch between a MUSB controller and a pair of OHCI/EHCI controller.

Enable PHY0 route auto switching for A64.

It's already documented.

In the H3 dual-route patchset I have already added this.

("  * "pmu0" for H3, V3s and A64")

P.S. to be compatible with older DTs, I think I should adjust
the phy driver, make it enable dual-route function only when
pmu0 is present.

That, or if we're quick enough, we can still add it to 4.11. There's a
bit of time left.

Thus the device tree binding patch and the DT part of this patchset
should be all pushed to 4.11 .

The device tree binding patch is commit ee73fd7dfc86 ("dt: bindings: add 
pmu0 regs for USB PHYs on Allwinner H3/V3s/A64").

It should have always been there. If there is a register for the PHY
somewhere, it must be in the DT node. Period. There's not relation to
whether the driver actually uses it or not.

Please send a patch to add that range for 4.11.
