Generic SYSCON mapped register poweroff driver
|
|
|
|
This is a generic poweroff driver using syscon to map the poweroff register.
|
|
The poweroff is generally performed with a write to the poweroff register
|
|
defined by the register map pointed by syscon reference plus the offset
|
|
with the value and mask defined in the poweroff node.
|
|
|
|
Required properties:
|
|
- compatible: should contain "syscon-poweroff"
|
|
- regmap: this is phandle to the register map node
|
|
- offset: offset in the register map for the poweroff register (in bytes)
|
|
- value: the poweroff value written to the poweroff 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:
|
|
|
|
poweroff {
|
|
compatible = "syscon-poweroff";
|
|
regmap = <®mapnode>;
|
|
offset = <0x0>;
|
|
mask = <0x7a>;
|
|
};
