Convert the marvell,armada3710-(sb|nb)-pinctrl binding to DT schema format. The binding includes the "marvell,armada-3700-xtal-clock" subnode which is simple enough to include here. Mark interrupt-controller/#interrupt-cells as required as the users have them and the h/w is either capable of interrupts or not. As this syscon has 2 register ranges, syscon-common.yaml needs to be updated to drop the restriction of 1 register entry.

title: System Controller Registers R/W Common Properties
|
|
|
|
description:
|
|
System controller node represents a register region containing a set
|
|
of miscellaneous registers. The registers are not cohesive enough to
|
|
represent as any specific type of device. The typical use-case is
|
|
for some other node's driver, or platform-specific code, to acquire
|
|
a reference to the syscon node (e.g. by phandle, node path, or
|
|
search using a specific compatible value), interrogate the node (or
|
|
associated OS driver) to determine the location of the registers,
|
|
and access the registers directly.
