    Subject[PATCH v2 04/12] clocksource: bindings: Provide bindings for ST's LPC Clocksource device
    Date
    On current ST platforms the LPC controls a number of functions including
    Watchdog and Real Time Clock. This patch provides the bindings used to
    configure LPC in Clocksource mode.

    +STMicroelectronics Low Power Controller (LPC) - Clocksource
    +===========================================================
    +
    +LPC currently supports Watchdog OR Real Time Clock OR Clocksource
    +functionality.
    +
    +[See: ../watchdog/st_lpc_wdt.txt for Watchdog options]
    +[See: ../rtc/rtc-st-lpc.txt for RTC options]
    +
    +Required properties
    +
    +- compatible : Must 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.
    +
    +Example:
    + lpc@fde05000 {
    + compatible = "st,stih407-lpc";
    + reg = <0xfde05000 0x1000>;
    + clocks = <&clk_s_d3_flexgen CLK_LPC_0>;
    + st,lpc-mode = <ST_LPC_MODE_CLKSRC>;
    + };
