* rtc/hctosys: only claim the RTC provided the system time if it didUwe Kleine-König2010-03-121-25/+34
| | | | | | | | | | | | | | | Without this patch /sys/class/rtc/$CONFIG_RTC_HCTOSYS_DEVICE/hctosys contains a 1 (meaning "This rtc was used to initialize the system clock") even if reading the time at bootup failed. Moreover change error handling in rtc_hctosys() to use goto and so reduce the indention level.

* rtc_hctosys expects RTCs in UTC (doc)David Brownell2007-11-141-2/+2
| | | | | | | | | | | | | | The RTC "hctosys" mechanism expects that RTC clock will use UTC, not local time (e.g. PST). Say so in Kconfig and in the kernel message. (Strictly speaking, the RTC clock should be tracking the POSIX epoch. That's not worth going into here. Goofing timezones means clocks are wrong by many hours; the POSIX-v-UTC differences just cost seconds.)

* rtc: remove rest of class_deviceDavid Brownell2007-05-081-3/+3
| | | | | | | | | | Finish converting the RTC framework so it no longer uses class_device.

* rtc: rtc interfaces don't use class_deviceDavid Brownell2007-05-081-7/+7
| | | | | | | | | | | | This patch removes class_device from the programming interface that the RTC framework exposes to the rest of the kernel. Now an rtc_device is passed, which is more type-safe and streamlines all the relevant code.

* [PATCH] RTC subsystem: classAlessandro Zummo2006-03-271-0/+69
Add the basic RTC subsystem infrastructure to the kernel. rtc/class.c - registration facilities for RTC drivers rtc/interface.c - kernel/rtc interface functions rtc/hctosys.c - snippet of code that copies hw clock to sw clock at bootup, if configured to do so.
