14 Bindings for Broadcom's BCM63xx memory-mapped GPIO controllers.
15
16 These bindings can be used on any BCM63xx SoC. However, BCM6338 and BCM6345
17 are the only ones which don't need a pinctrl driver.
18
19 BCM6338 have 8-bit data and dirout registers, where GPIO state can be read
20 and/or written, and the direction changed from input to output.
21 BCM6318, BCM6328, BCM6358, BCM6362, BCM6368 and BCM63268 have 32-bit data
22 and dirout registers, where GPIO state can be read and/or written, and the
23 direction changed from input to output.
