* rtc: mark if rtc-cmos drivers were successfully registeredThadeu Lima de Souza Cascardo2009-07-29
| | | | | | | | | | | | | | | | | | | | | | | rtc-cmos has two drivers, one PNP and one platform. When PNP has not succeeded probing, platform is registered. However, it tries to unregister both drivers unconditionally, instead of only unregistering those that were successfully registered. This causes runtime warnings to be emitted from the driver core code. Fix this with a boolean variable for each driver indicating whether registering was successful.

* bfin: delay IRQ registration until driver is readyMike Frysinger2009-06-30
| | | | | | | | | | | | Make sure we do not actually request the RTC IRQ until the device driver is fully ready to handle and process any interrupt. This way a spurious interrupt won't crash the system (which may happen if the bootloader was poking the RTC right before booting Linux).

* rtc: add stand-alone driver for RX8025 chipWolfgang Grandegger2009-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the Epson RX-8025SA/NB RTC chips. It includes support for alarms, periodic interrupts (1 Hz) and clock precision adjustment. For clock precision adjustment, the SYSFS file "clock_adjust_ppb" gets created in "/sys/class/rtc/rtcX/device". It permits to set and get the clock adjustment in ppb (parts per billion), e.g.: # echo -183000 > /sys/class/rtc/rtc0/device/clock_adjust_ppb # cat /sys/class/rtc/rtc0/device/clock_adjust_ppb -183000 This allows to compensate temperature dependent clock drifts. According to the RX8025 SA/NB application manual the frequency and temperature characteristics can be approximated using the following equation: df = a * (ut - t)**2 df: Frequency deviation in any temperature a : Coefficient = (-35 +-5) * 10**-9 ut: Ultimate temperature in degree = +25 +-5 degree t : Any temperature in degree Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: Sergei Poselenov <sposelenov@emcraft.com> Signed-off-by: Yuri Tikhonov <yur@emcraft.com> Signed-off-by: Dmitry Rakhchev <rda@emcraft.com> Signed-off-by: Matthias Fuchs <matthias.fuchs@esd.eu> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Alessandro Zummo <a.zummo@towertech.it> Cc: David Brownell <david-b@pacbell.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* rtc: rtc-ds1742 nvram attribute fixTorsten Ertbjerg Rasmussen2009-06-18
| | | | | | | | | | | | | | | | | | | | | | The RTC driver for ds1742 / ds1743 uses a static nvram attribute. This patch replaces this static attribute with one nvram attribute for each ds174x registered. The nvram size is not the same for all types of ds174x. The nvram size is accessible as the file size of the nvram attribute in sysfs. With only a single nvram attribute, this file size will be incorrect if more than one type of ds174x is present on a system. See the comment in the removed code below. This patch have been tested with linux-2.6.28 and linux-2.6.29-rc5/6 on a custom board with one ds1743.

| * [ARM] 5544/1: Trust PrimeCell resource sizesLinus Walleij2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I found the PrimeCell/AMBA Bus drivers distrusting the resource passed in as part of the struct amba_device abstraction. This patch removes all hard coded resource sizes found in the PrimeCell drivers and move the responsibility of this definition back to the platform/board device definition, which already exist and appear to be correct for all in-tree users of these drivers. We do this using the resource_size() inline function which was also replicated in the only driver using the resource size, so that has been changed too. The KMI_SIZE was left in kmi.h in case someone likes it. Test-compiled against Versatile and Integrator defconfigs, seems to work but I don't posess these boards and cannot test them.

* rtc: convert LEAP_YEAR into an inlineAndrew Morton2009-04-01
| | | | | | | | | | | | | | | | | - the LEAP_YEAR macro is buggy - it references its arg multiple times. Fix this by turning it into a C function. - give it a more approriate name - Move it to rtc.h so that other .c files can use it, instead of copying it.
