 STMicroelectronics Low Power Controller (LPC) - RTC
 ===================================================
 
-LPC currently supports Watchdog OR Real Time Clock functionality.
+LPC currently supports Watchdog OR Real Time Clock OR Clocksource
+functionality.
 
 [See: ../watchdog/st_lpc_wdt.txt for Watchdog options]
+[See: ../timer/st,stih407-lpc for Clocksource options]
 
 Required properties
 
-- compatible   : Must be one of: "st,stih407-lpc" "st,stih416-lpc"
-                                 "st,stih415-lpc" "st,stid127-lpc"
+- 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 two modes ST_LPC_MODE_RTC [0] or
-                 ST_LPC_MODE_WDT [1].  One (and only one) mode must be
-                 selected.
+- 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 {
