Add vcc5v0_host regulator for usb2-phy and enable host-port support.
Signed-off-by: Frank Wang <frank.wang@xxxxxxxxxxxxxx>
applied to ny dts64 branch [0] with some changes:
- the pin is named vcc5v0_host_en not host_vbus_drv in the schematics
please always try to use the names from the schematics
- separated the enablement of the subnodes
Thanks for your valuable comments, I will try to improve the quality of
my patches in future.
BR.
