- The OFFSET cell is an address of a bus mask. The buses can be
AHB and APB[A-D]. Each bus mask can enable a paripheral clock
selecting the BIT position in the mask.
- The BIT cell is the peripheral bit mask.
These information are used on PM and MCLK register to select the
clock for an specific peripheral. The generator 2 is used on this
example and can be defined by the user at board.
Example: Enable SERCOM0 on SAMD21
&sercom0 {
clocks = <&gclk 0x14>, <&pm 0x20 2>;
clock-names = "GCLK", "PM";
atmel,assigned-clocks = <&gclk 2>;
atmel,assigned-clock-names = "GCLK";
};
Example: Enable SERCOM0 on SAME54
&sercom0 {
clocks = <&gclk 7>, <&mclk 0x14 12>;
clock-names = "GCLK", "MCLK";
atmel,assigned-clocks = <&gclk 2>;
atmel,assigned-clock-names = "GCLK";
};

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
