2007-02-11[PATCH] RTC framework driver for CMOS RTCsDavid Brownell
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.

2007-02-09[PATCH] rtc-pcf8563: detect polarity of century bit automaticallyAtsushi Nemoto
The usage of the century bit was inverted on 2.6.19 following to PCF8563's description, but it was not match to usage suggested by RTC8564's datasheet. Anyway what MO_C=1 means can vary on each platform. This patch is to detect its polarity in get_datetime routine. The default value of c_polarity is 0 (MO_C=1 means 19xx) so that this patch does not change current behavior even if get_datetime was not called before set_datetime.

2007-01-05[PATCH] Update the rtc-rs5c372 driverDavid Brownell
Bugfixes: - Handle RTCs which are configured to use 12-hour mode. - Never report bogus/un-initialized times. - Displaying "raw trim" requires not masking it first! - Fix the sysfs and procfs display of crystal and trim data. Features: - Handle other RTCs in this family, notably rv5c386/rv5c387. - Declare the other registers. - Provide alarm get/set functionality. - Handle AIE and UIE; but no IRQ handling yet. Cleanup: - Shrink object by not including needless sysfs or procfs support - We don't need no steenkin' forward declarations. (Except one.) Until the I2C framework merges "new style" driver support, matching the driver model better, using rv5c chips or alarm IRQs requires a separate board-specific patch. (And an IRQ handler, handing off labor through a work_struct...) This uses the "method 3" register reads, but notes that it's done to work around an evident i2c adapter driver bug.

Also, update a few of the RTC drivers to stop providing that duplicate status, and/or to expose it properly when reporting the alarm state.

2006-12-12rtc: rtc-sh: alarm support.Jamie Lenehan
This adds alarm support for the RTC_ALM_SET, RTC_ALM_READ, RTC_WKALM_SET and RTC_WKALM_RD operations to rtc-sh. The only unusual part is the handling of the alarm interrupt. If you clear the alarm flag (AF) while the time in the RTC still matches the time in the alarm registers than AF is immediately re-set, and if the alarm interrupt (AIE) is still enabled then it re-triggers. I was originally getting around 20k+ interrupts generated during the second when the RTC and alarm registers matches. The solution I've used is to clear AIE when the alarm goes off and then use the carry interrupt to re-enabled it. The carry interrupt will check AF and re-enabled AIE if it's clear. If AF is not clear it'll clear it and then the check will be repeated next carry interrupt. This a bit in rtc structure that indicates that it's waiting to have AIE re-enabled so it doesn't turn it on when it wasn't enabled anyway.

This wasn't being taken into account in rtc-sh resulting in the month being out by one. eg, on my board during boot the RTC is set to: RTC is set to Thu Jul 01 09:00:00 1999 but "hwclock -r" immediately after logging in was showing: Sun Aug 1 09:01:43 1999 0.000000 seconds Signed-off-by: Jamie Lenehan <lenehan@twibble.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

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.

2006-11-25[PATCH] rtc framework handles periodic irqsDavid Brownell

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

2006-08-27[PATCH] drivers/rtc: fix rtc-s3c.cBen Dooks
In the cleanups of drivers/rtc/s3c-rtc.c, the base address for the registers got broken. This patch fixes that by ensuring the readb/writeb are all prefixed with the base returned from ioremap()ing the registers. Also fix check for valid year range, which was the wrong way around.
