Bin Meng	d24c7fbcc5	dm: rtc: Add 16-bit read/write support ... At present there are only 8-bit and 32-bit read/write routines in the rtc uclass driver. This adds the 16-bit support. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>	2017-04-10 10:02:03 +08:00
Simon Glass	9a4eb5977a	dm: rtc: Correct rtc_read32() return value ... The current check is incorrect and will fail when any non-zero byte is read. Fix it. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>	2015-10-21 07:46:50 -06:00
Simon Glass	dbeda5b225	dm: rtc: Add a uclass for real-time clocks ... Add a uclass for real-time clocks which support getting the current time, setting it and resetting the chip to a known-working state. Some RTCs have additional registers which can be used to store settings, so also provide an interface to these. Signed-off-by: Simon Glass <sjg@chromium.org>	2015-05-05 20:58:39 -06:00
