[ARM] rtc-pcf8583: Final fixes for this RTC on RiscPC

2007-03-04T20:33:07+00:00

Replace the I2C bus address, as per drivers/acorn/char/pcf8583.c.

Also, since this driver also contains Acorn RiscPC specific code
for obtaining the current year from the SRAM (and updating the
platform specific checksum when writing new data back) this is
NOT a platform independent driver.

Document it as such, and update the dependencies to reflect this
fact.

This option is useful for all of the X86 subarchs afaik (and especially
X86_GENERICARCH).

[PATCH] RTC framework driver for CMOS RTCs

2007-02-11T18:51:32+00:00

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 RTC

2006-12-10T17:55:40+00:00

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 support

2006-12-07T16:39:43+00:00

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 driver

2006-12-07T16:39:40+00:00

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 improvements

2006-10-01T07:39:25+00:00

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.
