* rtc: at91sam9 RTC support (RTT and/or RTC)David Brownell2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

* rtc: ds1302 rtc supportPaul Mundt2008-02-06
| | | | | | | | | | | | | | | | | 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 Brownell2007-11-14
| | | | | | | | | | | | | | 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.)

* OMAP: add TI TWL92330/Menelaus Power Management chip driverTony Lindgren2007-07-17
| | | | | | | | | | | | | | | | | | | | | | Add Texas Instruments TWL92330/Menelaus Power Management chip driver. This includes voltage regulators, Dual slot memory card tranceivers and real-time clock(RTC). The support for RTC is integrated with this driver only; it is not separate module. Passes 'rtctest' on OMAP H4 EVM, other than lack of "periodic" (1/N second) IRQs. System wakeup alarms (from suspend-to-RAM) work too. The battery keeps the RTC active over power off, so once you set clock (rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will behave as expected.

Only one defconfig -- powerpc/linkstation -- uses this driver; but several other platforms use it, just without defconfig support.

* rtc: suspend()/resume() restores system clockDavid Brownell2007-05-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | RTC class suspend/resume support, re-initializing the system clock on resume from the clock used to initialize it at boot time. - The reinit-on-resume is hooked to the existing RTC_HCTOSYS config option, on the grounds that a clock good enough for init must also be good enough for re-init. - Inlining a version of the code used by ARM, to save and restore the delta between a selected RTC and the current system wall-clock time. - Removes calls to that ARM code from AT91, OMAP1, and S3C RTCs. This means that systems using those RTCs across suspend/resume will likely want to change their kernel configs to enable RTC_HCTOSYS. If HCTOSYS isn't using a second RTC (with battery?), this changes the system's initial date from Jan 1970 to the epoch this hardware uses: 1998 for AT91, 2000 for OMAP1 (assuming no split power mode), etc. This goes on top of the patch series removing "struct class_device" usage from the RTC framework. That's all needed for class suspend()/resume().

* [PATCH] RTC framework driver for CMOS RTCsDavid Brownell2007-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an "RTC framework" driver for the "CMOS" RTCs which are standard on PCs and some other platforms. That's MC146818 compatible silicon. Advantages of this vs. drivers/char/rtc.c (use one _or_ the other, only one will be able to claim the RTC irq) include: - This leverages both the new RTC framework and the driver model; both PNPACPI and platform device modes are supported. (A separate patch creates a platform device on PCs where PNPACPI isn't configured.) - It supports common extensions like longer alarms. (A separate patch exports that information from ACPI through platform_data.) - Likewise, system wakeup events use "real driver model support", with policy control via sysfs "wakeup" attributes and and using normal rtc ioctls to manage wakeup. (Patch in the works. The ACPI hooks are known; /proc/acpi/alarm can vanish. Making it work with EFI will be a minor challenge to someone with e.g. a MiniMac.) It's not yet been tested on non-x86 systems, without ACPI, or with HPET. And the RTC framework will surely have teething pains on "mainstream" PC-based systems (though must embedded Linux systems use it heavily), not limited to sorting out the "/dev/rtc0" issue (udev easily tweaked). Also, the ALSA rtctimer code doesn't use the new RTC API. Otherwise, this should be a no-known-regressions replacement for the old drivers/char/rtc.c driver, and should help the non-embedded distros (and the new timekeeping code) start to switch to the framework. Note also that any systems using "rtc-m48t86" are candidates to switch over to this more functional driver; the platform data is different, and the way bytes are read is different, but otherwise those chips should be compatible.

* [PATCH] AT91RM9200 RTCAndrew Victor2006-12-10
| | | | | | | | | | | | | | The new Atmel AT91SAM9261 and AT91SAM9260 processors do not have the internal RTC peripheral. This RTC driver is therefore AT91RM9200-specific. This patch renames rtc-at91.c to rtc-at91rm9200.c, and changes the name of the configuration option.

* [PATCH] rtc: ds1743 supportTorsten Ertbjerg Rasmussen2006-12-07
| | | | | | | | | | | | | | | | The real time clocks ds1742 and ds1743 differs only in the size of the nvram. This patch changes the existing ds1742 driver to support also ds1743. The main change is that the nvram size is determined from the resource attached to the device. The patch have benefitted from suggestions from Atsushi Nemeto, who is the author of the ds1742 driver.

* [PATCH] add rtc-omap driverDavid Brownell2006-12-07
| | | | | | | | | | | | | | This creates a new RTC-framework driver for the RTC/calendar module found in various OMAP1 chips. (OMAP2 and OMAP3 use external RTCs, like those in TI's multifunction PM companion chips.) It's been in the Linux-OMAP tree for several months now, and other trees before that, so it's quite stable. The most notable issue is that the OMAP IRQ code doesn't yet support the RTC IRQ as a wakeup event. Once that's fixed, a patch will be needed.

* [PATCH] RTC class: Kconfig improvementsDavid Brownell2006-10-01
| | | | | | | | | | | | | | | | Small updates to make the RTC class Kconfig text be more informative. This should help folk used to the drivers/char/rtc.c support, or a single RTC, be slightly less surprised by the differences. Also, adds a new RTC_DEBUG option to predefine DEBUG in the framework and its drivers, while debugging. That's getting to be a standard idiom, and it's pretty useful.
