TPS65910A3EVM-583: 使用65910中的RTC代替OMAP_RTC

Part Number: TPS65910A

大家好!

我现在使用AM3352+TPS65910方案,Linux内核版本为4.1.18,想使用TPS65910的RTC代替OMAP_RTC,但是在内核启动过程中,无法识别65910,请问我该怎么做呢?相关信息如下:

1)部分原理图:

    

2)在内核源码中,存在以下与65910相关的驱动代码:

    a)./drivers/regulator/tps65910-regulator.c

    b)./drivers/mfd/tps65910.c

    c)./drivers/rtc/rtc-tps65910.c

    d)./drivers/gpio/gpio-tps65910.c

3)通过dmesg搜索内核启动过程中的rtc相关信息,结果如下:

    # dmesg | grep rtc
    [ 2.794655] hctosys: unable to open rtc device (rtc0)
    [ 7.113963] omap_rtc 44e3e000.rtc: already running
    [ 7.114394] omap_rtc 44e3e000.rtc: rtc core: registered 44e3e000.rtc as rtc0
    [ 7.242790] PM: bootloader does not support rtc-only!
