| STMicroelectronics Low Power Controller (LPC) - RTC | |
| =================================================== | |
| 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: "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_RTC>; | |
| }; |
