Pin control registers are part of both chip controller and system controller
|
|
register sets. Pin controller nodes should be a sub-node of either the chip
|
|
controller or system controller node. The pins controlled are organized in
|
|
groups, so no actual pin information is needed.
|
|
|
|
A pin-controller node should contain subnodes representing the pin group
|
|
configurations, one per function. Each subnode has the group name and the
|
|
muxing function used.
|
|
|
|
Be aware the Marvell Berlin datasheets use the keyword 'mode' for what is
|
|
called a 'function' in the pin-controller subsystem.
