2008-05-03RTC: Fix month offset by one problem in M41T62 RTC driverStefan Roese
This patch fixes a problem with the month being read and written incorrectly (offset by one). This only gets visible by also using the Linux driver (rtc-m41t80). Tested on AMCC Canyonlands. Signed-off-by: Stefan Roese <[email protected]>
2008-04-18RTC driver for MC13783Guennadi Liakhovetski
MC13783 is a multifunction IS with an SPI interface to the host. This driver handles the RTC controller in this chip. Signed-off-by: Guennadi Liakhovetski <[email protected]>

2008-03-26Add CFG_RTC_DS1337_NOOSC to turn off OSC outputJoakim Tjernlund
The default settings for RTC DS1337 keeps the OSC output, 32,768 Hz, on. This add CFG_RTC_DS1337_NOOSC to turn it off. Signed-off-by: Joakim Tjernlund <[email protected]>

2008-03-20LWMON5: POST RTC fixYuri Tikhonov
Modify the RTC API to provide one a status for the time reported by the rtc_get() function: 0 - a reliable time is guaranteed, < 0 - a reliable time isn't guaranteed (power fault, clock issues, and so on). The RTC chip drivers are responsible for providing this info if the corresponding chip supports such functionality. If not - always report that the time is reliable. The POST RTC test was modified to detect the RTC faults utilizing this new rtc_get() feature. Signed-off-by: Yuri Tikhonov <[email protected]>

2007-12-27Add driver for STMicroelectronics M41T60 RTCLarry Johnson
This driver is based on the driver for the M41T11. In the intended application, the RTC will be powered by a large capacitor, rather than a battery. The driver therefore checks to see whether the RTC has lost power. The chip's OUT bit is normally reset from its power-up state. If the OUT bit is read as set, or if the date and time are not valid, then the RTC is assumed to have lost power, and its date and time are reset to 1900-01-01 00:00:00. Support for adjusting the speed of the clock to improve accuracy is provided through an environment variable. Signed-off-by: Larry Johnson <[email protected]>
