dt-bindings: phy: sun4i-usb-phy: Add property descriptions for H3
The Allwinner H3 SoC has 4 USB PHYs, so it needs four sets of pmu regions, clocks, resets, and optional vbus properties. These were not described when the H3 compatible string was added. Fixes: 626a630e003c ("phy-sun4i-usb: Add support for the host usb-phys found on the H3 SoC") Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
