#     
#        - Enable ULPI drivers on i.MX to avoid a hang
#     
#        - Pinctrl fix for touchscreen on i.MX51 ZII RDU1
#     
#        - Fixes for ethernet clock references on am3517
#     
#        - mmc0 write protect detection fix for am335x
#     
#        - kzalloc->kcalloc conversion in an OMAP driver
#     
#        - USB metastability fix for USB on dra7
#     
#        - Fix touchscreen wakeup on am437x"
