| Subject | [PATCH 09/21] usb: chipidea: Add support for ULPI PHY bus |
| Date | 2016-06-26 09:40 +0200 |

Some phys for the chipidea controller are controlled via the ULPI
viewport. Add support for the ULPI bus so that these sorts of
phys can be probed and read/written automatically without having
to duplicate the viewport logic in each phy driver.
