I'm trying to play the series on db410c, and it doesn't seem to work as
expected. Here is basically what I did:
- Revert ed75d6a96905, and apply the series.
- Turn on the following options:
CONFIG_USB_CHIPIDEA_ULPI
CONFIG_USB_ULPI_BUS
CONFIG_PHY_QCOM_USB_HS
CONFIG_MUX_GPIO
The role switching doesn't happen when I connect/disconnect cable
to/from micro-usb port. But if I revert above extcon change (keep two
usb_id phandle for extcon), the role switching happens. However, host
driver still fails to enumerate the usb mouse attached to Type-A port.

I must have missed something. Can you please advice? Thanks.
