usb: phy: Workaround for USB erratum-A005728 PHY_CLK_VALID bit for UTMI PHY in USBDR does not set even if PHY is providing valid clock. Workaround for this involves resetting of PHY and check PHY_CLK_VALID bit multiple times. If PHY_CLK_VALID bit is still not set even after 5 retries, it would be safe to deaclare that PHY clock is not available. This erratum is applicable for USBDR less then ver 2.4.
