am4372-rtc string was already part of dts, introduced to identify the rtc specific to am4372 family of SoCs. It was removed in one of the previous patches. Adding back the same with appropriate documentation. Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

Required properties:
|
|
- compatible:
|
|
- "ti,da830-rtc" - for RTC IP used similar to that on DA8xx SoC family.
|
|
- "ti,am3352-rtc" - for RTC IP used similar to that on AM335x SoC family.
|
|
This RTC IP has special WAKE-EN Register to enable
|
|
Wakeup generation for event Alarm. It can also be
|
|
used to control an external PMIC via the
|
|
pmic_power_en pin.
|
|
- "ti,am4372-rtc" - for RTC IP used similar to that on AM437X SoC family.
|
|
- reg: Address range of rtc register set
|
|
- interrupts: rtc timer, alarm interrupts in order
|
|
- interrupt-parent: phandle for the interrupt controller
|
|
|
|
Optional properties:
|
|
- system-power-controller: whether the rtc is controlling the system power
|
|
through pmic_power_en
|
|
|
|
Example:
|
|
|
|
rtc@1c23000 {
|
|
compatible = "ti,da830-rtc";
|
|
reg = <0x23000 0x1000>;
|
|
interrupts = <19
|
|
19>;
|
|
interrupt-parent = <&intc>;
|
|
system-power-controller;
|
|
};
