| 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>; |
| }; |
