    1 STMicroelectronics Low Power Controller (LPC) - Watchdog
    2 ========================================================
    3 
    4 LPC currently supports Watchdog OR Real Time Clock OR Clocksource
    5 functionality.
    6 
    7 [See: ../rtc/rtc-st-lpc.txt for RTC options]
    8 [See: ../timer/st,stih407-lpc for Clocksource options]
    9 
   10 Required properties
   11 
   12 - compatible    : Should 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 
   22 Required properties [watchdog mode]
   23 
   24 - st,syscfg     : Phandle to syscfg node used to enable watchdog and configure
   25                   CPU reset type.
   26 - timeout-sec   : Watchdog timeout in seconds
   27 
   28 Optional properties [watchdog mode]
   29 
   30 - st,warm-reset : If present reset type will be 'warm' - if not it will be cold
   31 
   32 Example:
   33         lpc@fde05000 {
   34                 compatible      = "st,stih407-lpc";
   35                 reg             = <0xfde05000 0x1000>;
   36                 clocks          = <&clk_s_d3_flexgen CLK_LPC_0>;
   37                 st,syscfg       = <&syscfg_core>;
   38                 timeout-sec     = <120>;
   39                 st,lpc-mode     = <ST_LPC_MODE_WDT>;
   40                 st,warm-reset;
   41         };
