* rtc: rtc-dm355evm driverDavid Brownell2009-02-051-0/+6
| | | | | | | | | | | | Simple RTC driver for the MSP430 firmware on the DM355 EVM board. Other than not supporting atomic reads/writes of all four bytes, this is reasonable as a basic no-alarm RTC.

| | | | | | | | | | | | | | | | | | | With PXA27x and above, a new RTC hardware block was added in addition to the legacy one which is also found on the SA1100 SOC family. This second RTC block is called "wristwatch" and "periodic interrupt" and works independently from the other RTC block.

|/ | | | | | | | | | | | | | | | This adds a driver for the RTC inside the TWL4030 multi-function device. It's a fairly basic RTC, with a wake-capable alarm. Note that many of the pre-release Overo boards now in circulation can't effectively use this RTC, because of a wiring error that puts its TWL chip into "secure" mode. (As in "secure yourself against tampering".) This isn't an issue on other OMAP3 boards now supported in mainline, such as Beagle and Labrador.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kconfig tweaks to help reduce RTC configuration bugs, by avoiding legacy RTC drivers when the generic RTC framework is enabled: - If rtc-cmos is selected, disable the legacy rtc driver; - When using generic RTC on x86, enable rtc-cmos by default; - In the old "chardev RTC" section of Kconfig, add a comment warning people off these (seven) legacy RTC drivers when the generic framework is in use. People can still use the legacy drivers if they want (or need) to. This doesn't fix the broken dependencies for the legacy "CMOS" RTC driver. Ideally it would be a full list of platforms where it works, not a partial list of ones where it won't. Or better yet, it would depend on a "HAVE_CMOS_RTC" flag defined by various platforms ... surely there's a Kconfig style guideline lurking there.

* rtc: at91sam9 RTC support (RTT and/or RTC)David Brownell2008-02-061-4/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AT91sam9 RTC support, primarily in the form of an RTT-as-RTC driver that was extracted from 2.6.23-at91 patch and updated: - Relies on now-merged platform updates, which associate the RTT hardware address with each RTT and use the "at91_rtt" name. - RTC framework related fixes and cleanups, notably: * removed now-needless suspend/resume clock offset logic * alarm read/write now respects the "enabled" flag * suspend always disables update irqs * shutdown (and startup) disables all irqs - Misc cleanup: * use dev_*() messaging * add comments * remove globals, * ... etc - Don't force use of RTT0 and GPBR0. Either resource may need to be used for other purposes (like NO_HZ support). - Update "AT91RM9200 RTC" Kconfig to allow it on SAM9RL chips (it has both RTT and RTC). Driver binding uses bus_find_device() to avoid needing any kind of "timer library" code when there's more than one RTT module. (This timer can be used as an RTC, to support NO_HZ operation, or potentially for other stuff. The choice is a per-system policy.)

| | | | | | | | | | | | | | | | | This adds a basic ds1302 RTC driver, which is basically a cleanup and move of the in-tree SH SecureEdge5410 code (which is currently located in arch/sh/board/snapgear/rtc.c) to drivers/rtc. This aims to be a building block that the M32R and CRIS code can be worked on top of, so we can get rid of drivers/char/ds1302.c and arch/cris/arch-v10/drivers/ds1302.c respectively, though more work is needed for this.

* rtc_hctosys expects RTCs in UTC (doc)David Brownell2007-11-141-1/+3
| | | | | | | | | | | | | | 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.)
