0001 STMicroelectronics Low Power Controller (LPC) - RTC
0002 ===================================================
0003
0004 LPC currently supports Watchdog OR Real Time Clock OR Clocksource
0005 functionality.
0006
0007 [See: ../watchdog/st_lpc_wdt.txt for Watchdog options]
0008 [See: ../timer/st,stih407-lpc for Clocksource options]
0009
0010 Required properties
0011
0012 - compatible : Must be: "st,stih407-lpc"
0013 - reg : LPC registers base address + size
0014 - interrupts : LPC interrupt line number and associated flags
0015 - clocks : Clock used by LPC device (See: ../clock/clock-bindings.txt)
0016 - st,lpc-mode : The LPC can run either one of three modes:
0017 ST_LPC_MODE_RTC [0]
0018 ST_LPC_MODE_WDT [1]
0019 ST_LPC_MODE_CLKSRC [2]
0020 One (and only one) mode must be selected.
0021
0022 Example:
0023 lpc@fde05000 {
0024 compatible = "st,stih407-lpc";
0025 reg = <0xfde05000 0x1000>;
0026 clocks = <&clk_s_d3_flexgen CLK_LPC_0>;
0027 st,lpc-mode = <ST_LPC_MODE_RTC>;
0028 };
