Generic SYSCON mapped register reset driver
|
|
|
|
This is a generic reset driver using syscon to map the reset register.
|
|
The reset is generally performed with a write to the reset register
|
|
defined by the register map pointed by syscon reference plus the offset
|
|
with the value and mask defined in the reboot node.
|
|
|
|
Required properties:
|
|
- compatible: should contain "syscon-reboot"
|
|
- regmap: this is phandle to the register map node
|
|
- offset: offset in the register map for the reboot register (in bytes)
|
|
- value: the reset value written to the reboot register (32 bit access)
|
|
|
|
Optional properties:
|
|
- mask: update only the register bits defined by the mask (32 bit)
|
|
|
|
Legacy usage:
|
|
If a node doesn't contain a value property but contains a mask property, the
|
|
mask property is used as the value.
|
|
|
|
Default will be little endian mode, 32 bit access only.
|
|
|
|
Examples:
|
|
|
|
reboot {
|
|
compatible = "syscon-reboot";
|
|
regmap = <®mapnode>;
|
|
offset = <0x0>;
|
|
mask = <0x1>;
|
|
};
