Feel free to put dt patches in a separate series after Miquel picks
up the mtd changes

Please pad the address part to 8 hex digits with leading zeroes

Please make clock/dma names a vertical list, like clocks/dmas

Also, is it okay not to use any of the GCC_QPIC_BCR/
GCC_QPIC_AHB_ARES/GCC_QPIC_ARES resets found in GCC?
