This results in a crash during suspend/resume operations.

This also fixes LTO builds that otherwise fail with section mismatch errors.

This is a generic function that performs the generic host stack's shutdown. It ensures that USB operations do not continue while kexec boots a new kernel.

Previously the phy-msm-usb driver would do this for us, but since ehci-msm can now be instantiated standalone without any PHY driver, the register needs to be explicitly initialized to ULPI mode to properly communicate with the PHY. This is not readily apparent, as firmware or bootloader code also happen to pre-initialize this for us. However, it can manifest when performing a driver unbind/rebind as follows: cd /sys/bus/platform/drivers/msm_hsusb_host echo QCOM8040:00 > unbind echo QCOM8040:00 > bind The EHCI core executes a controller reset as part of this, and as a result the register in question would revert to its default state and must be re-initialized properly. Furthermore this may be useful in the future when adding PM suspend/resume support.

In some cases or board configurations we want to allow the EHCI host to be instantiated without OTG capability. Instead, relax the dependency on having an OTG PHY being present and call usb_add_hcd() directly.
