1STMicroelectronics Low Power Controller (LPC) - RTC 2=================================================== 3 4LPC currently supports Watchdog OR Real Time Clock OR Clocksource 5functionality. 6 7[See: ../watchdog/st_lpc_wdt.txt for Watchdog options] 8[See: ../timer/st,stih407-lpc for Clocksource options] 9 10Required properties 11 12- compatible : Must be: "st,stih407-lpc" 13- reg : LPC registers base address + size 14- interrupts : LPC interrupt line number and associated flags 15- clocks : Clock used by LPC device (See: ../clock/clock-bindings.txt) 16- st,lpc-mode : The LPC can run either one of three modes: 17 ST_LPC_MODE_RTC [0] 18 ST_LPC_MODE_WDT [1] 19 ST_LPC_MODE_CLKSRC [2] 20 One (and only one) mode must be selected. 21 22Example: 23 lpc@fde05000 { 24 compatible = "st,stih407-lpc"; 25 reg = <0xfde05000 0x1000>; 26 clocks = <&clk_s_d3_flexgen CLK_LPC_0>; 27 st,lpc-mode = <ST_LPC_MODE_RTC>; 28 };
