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