2006-12-12[PATCH] remove config ordering/dependency between ucb1400-ts and sound subsystemNicolas Pitre
Commit 2d4ba4a3b9aef95d328d74a17ae84f8d658059e2 introduced a dependency that was never meant to exist when the ac97_bus.c module was created. Move ac97_bus.c up the directory hierarchy to make sure it is built when selected even if sound is configured out so things work as originally intended.

2006-12-12[PATCH] remove blk_queue_activity_fnBoaz Harrosh
While working on bidi support at struct request level I have found that blk_queue_activity_fn is actually never used. The only user is in ide-probe.c with this code: /* enable led activity for disk drives only */ if (drive->media == ide_disk && hwif->led_act) blk_queue_activity_fn(q, hwif->led_act, drive); And led_act is never initialized anywhere. (Looking back at older kernels it was used in the PPC arch, but was removed around 2.6.18) Unless it is all for future use off course.

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.

2006-12-12rtc: rtc-sh: fix rtc for out-by-one for the month.Jamie Lenehan
The RMONCNT register, which holds the month in the RTC, takes a value between 1 and 12 while the tm_mon field in the time structures takes a value between 0 and 11. 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>

2006-12-11AT91 MMC update for 2.6.19Andrew Victor
The driver is usable on the newer SAM9 processors so replace all text references to AT91RM9200 with just AT91. The controller bug where all the words are byte-swapped is fixed on the AT91SAM9 processors. The byte-swapping work-around therefore only needs to be done if cpu_is_at91rm9200(). [Original patch from Wojtek Kaniewski] The AT91RM9200 and AT91SAM9260 processors support two MMC/SD slots - the slot which is connected is now passed via the platform_data and the correct slot selected in the AT91_MCI_SDCR register. The driver should not be calling at91_set_gpio_output() since the VCC pin should have already been configured as an output in the processor/board setup code.

2006-12-10i2c: fix broken ds1337 initializationDirk Eibach
On a custom board with ds1337 RTC I found that upgrade from 2.6.15 to 2.6.18 broke RTC support. The main problem are changes to ds1337_init_client(). When a ds1337 recognizes a problem (e.g. power or clock failure) bit 7 in status register is set. This has to be reset by writing 0 to status register. But since there are only 16 byte written to the chip and the first byte is interpreted as an address, the status register (which is the 16th) is never written. The other problem is, that initializing all registers to zero is not valid for day, date and month register. Funny enough this is checked by ds1337_detect(), which depends on this values not being zero. So then treated by ds1337_init_client() the ds1337 is not detected anymore, whereas the failure bit in the status register is still set.
