   1 STMicroelectronics Low Power Controller (LPC) - RTC
   2 ===================================================
   3
   4 LPC currently supports Watchdog OR Real Time Clock OR Clocksource
   5 functionality.

   8 [See: ../timer/st,stih407-lpc for Clocksource options]

  10 Required 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.

  22 Example:
  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         };
