14 Bindings for Broadcom's BCM63xx memory-mappe
15
16 These bindings can be used on any BCM63xx So
17 are the only ones which don't need a pinctrl
18
19 BCM6338 have 8-bit data and dirout registers
20 and/or written, and the direction changed fr
21 BCM6318, BCM6328, BCM6358, BCM6362, BCM6368
22 and dirout registers, where GPIO state can b
23 direction changed from input to output.
