USB: add USB EHCI support for MPC5121 SoC
Extends FSL EHCI platform driver glue layer to support MPC5121 USB controllers. MPC5121 Rev 2.0 silicon EHCI registers are in big endian format. The appropriate flags are set using the information in the platform data structure. MPC83xx system interface registers are not available on MPC512x, so the access to these registers is isolated in MPC512x case. Furthermore the USB controller clocks must be enabled before 512x register accesses which is done by providing platform specific init callback. The MPC512x internal USB PHY doesn't provide supply voltage. For boards using different power switches allow specifying DRVVBUS and PWR_FAULT signal polarity of the MPC5121 internal PHY using "fsl,invert-drvvbus" and "fsl,invert-pwr-fault" properties in the device tree USB nodes. Adds documentation for this new device tree bindings. Signed-off-by: Anatolij Gustschin <agust@denx.de> Cc: Grant Likely <grant.likely@secretlab.ca> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
