SHDWC Shutdown Controller
required properties:
- compatible: Should be "atmel,<chip>-shdwc".
<chip> can be "at91sam9260", "at91sam9rl" or "at91sam9x5".
- reg: Should contain registers location and length
- clocks: phandle to input clock.
optional properties:
- atmel,wakeup-mode: String, operation mode of the wakeup mode.
Supported values are: "none", "high", "low", "any".
- atmel,wakeup-counter: Counter on Wake-up 0 (between 0x0 and 0xf).
optional at91sam9260 properties:
- atmel,wakeup-rtt-timer: boolean to enable Real-time Timer Wake-up.
optional at91sam9rl properties:
- atmel,wakeup-rtc-timer: boolean to enable Real-time Clock Wake-up.
- atmel,wakeup-rtt-timer: boolean to enable Real-time Timer Wake-up.
optional at91sam9x5 properties:
- atmel,wakeup-rtc-timer: boolean to enable Real-time Clock Wake-up.
Example:
shdwc@fffffd10 {
compatible = "atmel,at91sam9260-shdwc";
reg = <0xfffffd10 0x10>;
clocks = <&clk32k>;
};
SHDWC SAMA5D2-Compatible Shutdown Controller
1) shdwc node
required properties:
- compatible: should be "atmel,sama5d2-shdwc", "microchip,sam9x60-shdwc" or
"microchip,sama7g5-shdwc"
- reg: should contain registers location and length
- clocks: phandle to input clock.
- #address-cells: should be one. The cell is the wake-up input index.
- #size-cells: should be zero.
optional properties:
- debounce-delay-us: minimum wake-up inputs debouncer period in
microseconds. It's usually a board-related property.
- atmel,wakeup-rtc-timer: boolean to enable Real-Time Clock wake-up.
optional microchip,sam9x60-shdwc or microchip,sama7g5-shdwc properties:
- atmel,wakeup-rtt-timer: boolean to enable Real-time Timer Wake-up.
The node contains child nodes for each wake-up input that the platform uses.
2) input nodes
Wake-up input nodes are usually described in the "board" part of the Device
Tree. Note also that input 0 is linked to the wake-up pin and is frequently
used.
Required properties:
- reg: should contain the wake-up input index [0 - 15].
Optional properties:
- atmel,wakeup-active-high: boolean, the corresponding wake-up input described
by the child, forces the wake-up of the core power supply on a high level.
The default is to be active low.
Example:
On the SoC side:
shdwc@f8048010 {
compatible = "atmel,sama5d2-shdwc";
reg = <0xf8048010 0x10>;
clocks = <&clk32k>;
#address-cells = <1>;
#size-cells = <0>;
atmel,wakeup-rtc-timer;
};
On the board side:
shdwc@f8048010 {
debounce-delay-us = <976>;
input@0 {
reg = <0>;
};
input@1 {
reg = <1>;
atmel,wakeup-active-high;

NVMEM reboot mode driver
This driver gets reboot mode magic value from reboot-mode driver
and stores it in a NVMEM cell named "reboot-mode". Then the bootloader
can read it and take different action according to the magic
value stored.
Required properties:
- compatible: should be "nvmem-reboot-mode".
- nvmem-cells: A phandle to the reboot mode provided by a nvmem device.
- nvmem-cell-names: Should be "reboot-mode".
The rest of the properties should follow the generic reboot-mode description
found in reboot-mode.txt
Example:
reboot-mode {
compatible = "nvmem-reboot-mode";
nvmem-cells = <&reboot_mode>;
nvmem-cell-names = "reboot-mode";
mode-normal = <0xAAAA5501>;
mode-bootloader = <0xBBBB5500>;
mode-recovery = <0xCCCC5502>;
mode-test = <0xDDDD5503>;
