2009-01-08rtc-ds1307: remove legacy probe() checksJüri Reitel
Remove RTC register value checks from the rtc-ds1307 probe() function. They were left over from the legacy style I2C driver, which had to defend against finding a non-RTC chip when the driver was probed. Also fix a minor glitch in the alarm support: DS1307 chips don't have alarms, so name those methods after one of the chips which actually *do* have alarms (DS1337).

2009-01-06rtc: bunch of drivers: fix 'no irq' case handingAnton Vorontsov
This patch fixes a bunch of irq checking misuses. Most drivers were getting irq via platform_get_irq(), which returns -ENXIO or r->start. rtc-cmos.c is special. It is using PNP and platform bindings. Hopefully nobody is using PNP IRQ 0 for RTC. So the changes should be safe. rtc-sh.c is using platform_get_irq, but was storing a result into an unsigned type, then was checking for < 0. This is fixed now.

2008-12-01[ARM] 5319/1: AT91: support AT91CAP9 revC CPUsStelian Pop
The AT91CAP9 revC CPU has a few differences over the previous, revB CPU which was distributed in small quantities only (revA was an internal Atmel product only). This patch adds the detection routines to recognize the different AT91CAP9 revisions (based on the PMC subsystem version number), and uses them to: - activate a workaround for the external interrupts levels (on revB CPUs) - set the UDPHS_BYPASS bit (on revB CPUs) - set AT91_GPBR register address to the correct offset (0xfffffd50 on revB, 0xfffffd60 on revC) For debugging usage, the CPU revision can be found in /proc/cpuinfo on the 'Revision' line. This patch is extracted from Andrew Victor's -at91 patch (2.6.27-at91.patch) where it has been tested for the last 6 months.

2008-11-12rtc: rtc-wm8350: add support for WM8350 RTCMark Brown
This adds support for the RTC provided by the Wolfson Microelectronics WM8350. This driver was originally written by Graeme Gregory and Liam Girdwood, though it has been modified since then to update it to current mainline coding standards and for API completeness.

2008-11-06rtc: fix handling of missing tm_year data when reading alarmsMark Brown
When fixing up invalid years rtc_read_alarm() was calling rtc_valid_tm() as a boolean but rtc_valid_tm() returns zero on success or a negative number if the time is not valid so the test was inverted.

2008-11-01saner FASYNC handling on file closeAl Viro
As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.
