- * Here we attempt to calculate these indexes from DT information as

- * and iMX7 their addresses are shifted by 0x10000.
- * Thus, the index is derived from the multiple of 0x200 (0x10000 for
- * iMX7) offset from the first controller address.
- *
- * However, to complete conversion of this driver to DT probing, the
- * following has to be done:
- * - DM clock framework support for iMX must be implemented
- * - usb_power_config() has to be converted to clock framework
- * -> Thus, the ad-hoc "index" variable goes away.
- * - USB PHY handling has to be factored out into separate driver
- * -> Thus, the ad-hoc "index" variable goes away from the PHY
- * code, the PHY driver must parse it's address from DT. This
- * USB driver must find the PHY driver via DT phandle.
- * -> usb_power_config() shall be moved to PHY driver
- * With these changes in place, the ad-hoc indexing goes away and
- * the driver is fully converted to DT probing.
