STMicroelectronics Low Power Controller (LPC) - Watchdog ======================================================== LPC currently supports Watchdog OR Real Time Clock OR Clocksource functionality. [See: ../rtc/rtc-st-lpc.txt for RTC options] [See: ../timer/st,stih407-lpc for Clocksource options] Required properties - compatible : Should 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. Required properties [watchdog mode] - st,syscfg : Phandle to syscfg node used to enable watchdog and configure CPU reset type. - timeout-sec : Watchdog timeout in seconds Optional properties [watchdog mode] - st,warm-reset : If present reset type will be 'warm' - if not it will be cold Example: lpc@fde05000 { compatible = "st,stih407-lpc"; reg = <0xfde05000 0x1000>; clocks = <&clk_s_d3_flexgen CLK_LPC_0>; st,syscfg = <&syscfg_core>; timeout-sec = <120>; st,lpc-mode = <ST_LPC_MODE_WDT>; st,warm-reset; };
