  1. STMicroelectronics Low Power Controller (LPC) - RTC
  2. ===================================================
  3. LPC currently supports Watchdog OR Real Time Clock functionality.
  4. [See: ../watchdog/st_lpc_wdt.txt for Watchdog options]
  5. Required properties
  6. - compatible : Must be one of: "st,stih407-lpc" "st,stih416-lpc"
  7. "st,stih415-lpc" "st,stid127-lpc"
  8. - reg : LPC registers base address + size
  9. - interrupts : LPC interrupt line number and associated flags
  10. - clocks : Clock used by LPC device (See: ../clock/clock-bindings.txt)
  11. - st,lpc-mode : The LPC can run either one of two modes ST_LPC_MODE_RTC [0] or
  12. ST_LPC_MODE_WDT [1]. One (and only one) mode must be
  13. selected.
  14. Example:
  15. lpc@fde05000 {
  16. compatible = "st,stih407-lpc";
  17. reg = <0xfde05000 0x1000>;
  18. clocks = <&clk_s_d3_flexgen CLK_LPC_0>;
  19. st,lpc-mode = <ST_LPC_MODE_RTC>;
  20. };
