- STMicroelectronics Low Power Controller (LPC) - RTC
- ===================================================
- LPC currently supports Watchdog OR Real Time Clock OR Clocksource
- functionality.
- [See: ../watchdog/st_lpc_wdt.txt for Watchdog options]
- [See: ../timer/st,stih407-lpc for Clocksource options]
- Required properties
- - compatible : Must be: "st,stih407-lpc"
- - reg : LPC registers base address + size
- - interrupts : LPC interrupt line number and associated flags
- - clocks : Clock used by LPC device (See: ../clock/clock-bindings.txt)
- - st,lpc-mode : The LPC can run either one of three modes:
- ST_LPC_MODE_RTC [0]
- ST_LPC_MODE_WDT [1]
- ST_LPC_MODE_CLKSRC [2]
- One (and only one) mode must be selected.
- Example:
- lpc@fde05000 {
- compatible = "st,stih407-lpc";
- reg = <0xfde05000 0x1000>;
- clocks = <&clk_s_d3_flexgen CLK_LPC_0>;
- st,lpc-mode = <ST_LPC_MODE_RTC>;
- };
