Ferry Toth 9bd180b6f9 usb: ulpi: defer ulpi_register on ulpi_read_id timeout ... [ Upstream commit 8a7b31d545 ] Since commit 0f01017191 ("usb: dwc3: Don't switch OTG -> peripheral if extcon is present") Dual Role support on Intel Merrifield platform broke due to rearranging the call to dwc3_get_extcon(). It appears to be caused by ulpi_read_id() on the first test write failing with -ETIMEDOUT. Currently ulpi_read_id() expects to discover the phy via DT when the test write fails and returns 0 in that case, even if DT does not provide the phy. As a result usb probe completes without phy. Make ulpi_read_id() return -ETIMEDOUT to its user if the first test write fails. The user should then handle it appropriately. A follow up patch will make dwc3_core_init() set -EPROBE_DEFER in this case and bail out.
