STMicroelectronics Low Power Controller (LPC) - Clocksource
===========================================================
LPC currently supports Watchdog OR Real Time Clock OR Clocksource
functionality.
[See: ../watchdog/st_lpc_wdt.txt for Watchdog options]
[See: ../rtc/rtc-st-lpc.txt for RTC 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_CLKSRC>;
};
