2008-02-06w1-gpio: add GPIO w1 bus master driverVille Syrjala
Add a GPIO 1-wire bus master driver. The driver used the GPIO API to control the wire and the GPIO pin can be specified using platform data similar to i2c-gpio. The driver was tested with AT91SAM9260 + DS2401.

2008-02-06rtc: at91sam9 RTC support (RTT and/or RTC)David Brownell
AT91sam9 RTC support, primarily in the form of an RTT-as-RTC driver that was extracted from 2.6.23-at91 patch and updated: - Relies on now-merged platform updates, which associate the RTT hardware address with each RTT and use the "at91_rtt" name. - RTC framework related fixes and cleanups, notably: * removed now-needless suspend/resume clock offset logic * alarm read/write now respects the "enabled" flag * suspend always disables update irqs * shutdown (and startup) disables all irqs - Misc cleanup: * use dev_*() messaging * add comments * remove globals, * ... etc - Don't force use of RTT0 and GPBR0. Either resource may need to be used for other purposes (like NO_HZ support). - Update "AT91RM9200 RTC" Kconfig to allow it on SAM9RL chips (it has both RTT and RTC). Driver binding uses bus_find_device() to avoid needing any kind of "timer library" code when there's more than one RTT module. (This timer can be used as an RTC, to support NO_HZ operation, or potentially for other stuff. The choice is a per-system policy.)

Remove some more references to dev->power.power_state. That field is overdue for removal, but we can't do that while it's still referenced in the kernel. The only reason to update it was to make the /sys/devices/.../power/state files (now removed) work better.

2008-02-06rtc-cmos alarm acts as oneshotDavid Brownell
Start making the rtc-cmos alarm act more like a oneshot alarm by disabling that alarm after its IRQ fires. (ACPI hooks are also needed.) The Linux RTC framework has previously been a bit vague in this area, but any other behavior is problematic and not very portable. RTCs with full YYYY-MM-DD HH:MM[:SS] alarms won't have a problem here. Only ones with partial match criteria, with the most visible example being the PC RTC, get confused. (Because the criteria will match repeatedly.) Update comments relating to that oneshot behavior and timezone handling. (Timezones are another issue that's mostly visible with rtc-cmos. That's because PCs often dual-boot MS-Windows, which likes its RTC to match local wall-clock time instead of UTC.)

This adds a basic ds1302 RTC driver, which is basically a cleanup and move of the in-tree SH SecureEdge5410 code (which is currently located in arch/sh/board/snapgear/rtc.c) to drivers/rtc. This aims to be a building block that the M32R and CRIS code can be worked on top of, so we can get rid of drivers/char/ds1302.c and arch/cris/arch-v10/drivers/ds1302.c respectively, though more work is needed for this.

2008-02-06rtc-cmos: export nvram in sysfsDavid Brownell
This makes rtc-cmos export its NVRAM, like several other RTC drivers. It still works within the limits of the current CMOS_READ/CMOS_WRITE calls, which don't understand how to access multiple register banks. The primary impact of that limitation is that Linux can't access the uppermost 128 bytes of NVRAM on many systems. Note that this isn't aiming to be a drop-in replacement for the legacy /dev/nvram support. (Presumably that has real users, and isn't just getting carried forward automatically?) Userspace handles more work: - When userspace code updates NVRAM, that will need to include updating any platform-specific checksums that may apply. - No /proc/driver/nvram file will parse and display NVRAM data according to whichever boot firmware your board expects. Also minor pnp-related updates: update a comment, remove dead code.

2008-02-06fuse: limit queued background requestsMiklos Szeredi
Libfuse basically creates a new thread for each new request. This is fine for synchronous requests, which are naturally limited. However background requests (especially writepage) can cause a thread creation storm. To avoid this, limit the number of background requests available to userspace. This is done by introducing another queue for background requests, and a counter for the number of "active" requests, which are currently available for userspace.

2008-02-06ecryptfs: check for existing key_tfm at mount timeEric Sandeen
Jeff Moyer pointed out that a mount; umount loop of ecryptfs, with the same cipher & other mount options, created a new ecryptfs_key_tfm_cache item each time, and the cache could grow quite large this way. Looking at this with mhalcrow, we saw that ecryptfs_parse_options() unconditionally called ecryptfs_add_new_key_tfm(), which is what was adding these items. Refactor ecryptfs_get_tfm_and_mutex_for_cipher_name() to create a new helper function, ecryptfs_tfm_exists(), which checks for the cipher on the cached key_tfm_list, and sets a pointer to it if it exists. This can then be called from ecryptfs_parse_options(), and new key_tfm's can be added only when a cached one is not found. With list locking changes suggested by akpm.

2008-02-06ecryptfs: remove debug as mount option, and warn if set via modprobeEric Sandeen

It's already settable as a module load option, I think we can leave it at that. Also, if set, since secret values come out in debug messages, kick things off with a stern warning.

2008-02-06spi_bfin: wait for tx to complete on full duplex pathsBryan Wu
Full duplex SPI operation should not read a dummy byte at the first transfer. Bug and fix by Jean-Christian de Rivaz <jc@eclis.ch>: http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3678 Signed-off-by: Jean-Christian de Rivaz <jc@eclis.ch> Signed-off-by: Bryan Wu <bryan.wu@analog.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2008-02-06spi_bfin: wait for tx to complete on some cs_chg pathsBryan Wu
PBX 2 SPI devices need the nonstandard "cs change per word" mechanism. This patch is one of three updating this driver to make the last data bits get sent before advancing the transfer ... in this case, before the chipselect gets deactivated.
