I talked with Al about this off list a bit, and pointed out it's different than it appears. GEN_RTC really is a mostly-generic RTC driver. There's some fakey stuff going on for UIE (all under GEN_RTC_X), but the real meat of the driver is common export get/set time and per-arch (which can abstract further, see ppc32) poke the hardware for the time. There's 2 (afaik) problems, one being a lack of alarm support, and the other being hardware access isn't (today) abstracted out far enough for i2c stuff to work. Russell King has both of these fixed in the ARM-specific but hardware poking abstracted rtc driver. I'd like to try and merge things at somepoint... -- Tom Rini http://gate.crashing.org/~trini/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
