Well, the omapdrm fixes aren't really "small" but they were waiting on a number of other drm patches to go in through the drm tree, and got delayed by my vacation over the holidays. They are totally self-contained, everyone involved have acked them, and they fix issues that people have been having with the driver. Other than that one, it's a bunch of tiny bugfixes for a number of reported issues.

Fix it. Driver should also not attempt to free the interrupt in its error path if none was allocated. Fix that problem as well.

We have several new drivers, most of the time coming with their sub devices drivers: - Austria Microsystem's AS3711 - Nano River's viperboard - TI's TPS80031, AM335x TS/ADC, - Realtek's MMC/memstick card reader - Nokia's retu We also got some notable cleanups and improvements: - tps6586x got converted to IRQ domains. - tps65910 and tps65090 moved to the regmap IRQ API. - STMPE is now Device Tree aware. - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ APIs and a conversion to the recently added PWM framework. - sta2x11 gained regmap support. Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts. Many due to __devinit/exit removal, others due to one or two of the new drivers also having come in through another tree. * tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (119 commits) mfd: tps6507x: Convert to devm_kzalloc mfd: stmpe: Update DT support for stmpe driver mfd: wm5102: Add readback of DSP status 3 register mfd: arizona: Log if we fail to create the primary IRQ domain mfd: tps80031: MFD_TPS80031 needs to select REGMAP_IRQ mfd: tps80031: Add terminating entry for tps80031_id_table mfd: sta2x11: Fix potential NULL pointer dereference in __sta2x11_mfd_mask() mfd: wm5102: Add tuning for revision B mfd: arizona: Defer patch initialistation until after first device boot mfd: tps65910: Fix wrong ack_base register mfd: tps65910: Remove unused data mfd: stmpe: Get rid of irq_invert_polarity mfd: ab8500-core: Fix invalid free of devm_ allocated data mfd: wm5102: Mark DSP memory regions as volatile mfd: wm5102: Correct default for LDO1_CONTROL_2 mfd: arizona: Register haptics devices mfd: wm8994: Make current device behaviour the default mfd: tps65090: MFD_TPS65090 needs to select REGMAP_IRQ mfd: Fix stmpe.c build when OF is not enabled mfd: jz4740-adc: Use devm_kzalloc ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Smatch complains that snprintf() returns the number of characters, not counting the NUL terminator, which *would* have been printed if there were enough space. In other words the return value could be more than sizeof(buf). In this case, we are printing something like "ff.ff\n" which is at most 6 characters and a NUL so that's not an issue. I changed snprintf() to scnprintf() to silence the warning. But since the buffer doesn't include space for the NUL terminator, we need to make it bigger or the "\n" will be truncated off.

| | | | | | | | | | | | | | | | | | | | | | It's slightly cleaner to use kstrtouint() because we pass unsigned ints to adis16136_set_freq().

* | iio:ad7793: Add support for the ad7796 and ad7797Lars-Peter Clausen2012-11-301-12/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | The ad7796 and ad7797 are similar to the ad7792 and ad7793 but only have a single differential input instead of two. Also some other features are missing like the programmable gain amplifier and also not all sampling frequencies supported by the ad7792/ad7793 are supported by the ad7796/ad7797. This patch adds new feature flags for the features not present in the ad7796/ad7797. The patch also adds a struct iio_info field to the chip_info struct, this becomes necessary since the ad7796/ad7797 needs a special set of sysfs attributes.

* | iio:imu:adis: Add paging supportLars-Peter Clausen2012-11-202-16/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of the newer generation devices from the ADIS16XXX series have more registers than what can be supported with the current register addressing scheme. These devices implement register paging to support a larger register range. Each page is 128 registers large and the currently active page can be selected via register 0x00 in each page. This patch implements transparent paging inside the common adis library. The register read/write interface stays the same and when a register is accessed the library automatically switches to the correct page if it is not already selected. The page number is encoded in the upper bits of the register number, e.g. register 0x5 of page 1 is 0x85.

* | iio: Reject trailing garbage when parsing fixed point numbersLars-Peter Clausen2012-11-021-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | When parsing a fixed point number IIO stops parsing the string once it has reached the last requested decimal place. This means that the remainder of the string is silently accepted regardless, of whether it is part of a valid number or not. This patch modifies the code to scan the whole string and only accept valid numbers. Since fract_mult is 0 after the last decimal place any digit that may follows won't affect the result.

* | iio: Do not accept multiple '.' in fixed point numbersLars-Peter Clausen2012-11-021-1/+1
| | | | | | | | | | | | | | | | | | Currently when parsing a fix-point number we silently skip any additional '.' found in the string. E.g. '1.2.3.4' gets parsed as '1.234'. This patch disallows this and returns an error if more than one '.' is encountered. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
