Report output values as 1/1000 of earth gravity. Output values from lis3 can be read from sysfs position entry and from input device. Input device can be accessed as event device and as joystick device. Joystick device can be in two modes. Meaning of the output values varies from case to case depending on the chip type and configuration (scale). Only joystick interface in JS_CORR_BROKEN mode returned somehow similar output values in different configurations. Joystick device is in that state by default in case of lis3. Position sysfs entry, input event device and raw joystick device have been little bit broken since meaning of the output values has been varied between 12 and 8 bit devices. Applications which relayed on those methods failed if the chip is different than the expected one. This patch converts output values to mean similar thing in different configurations. Both 8 and 12 bit devices reports now same acceleration values. If somebody implements full scale support to the driver, output values will still mean the same. Scaling factor and input device range must be updated in that case. Joystick interface in JS_CORR_BROKEN mode is not touched by this patch. All other interfaces have different scale after this change. For 12 bit device scaling factor is 0.977 which keeps scaled and unscaled values are quite close to each others. For 8 bit device, scaled values are 18 times bigger than unscaled values. Signed-off-by:

Implement selftest feature as specified by chip manufacturer. Control: read selftest sysfs entry Response: "OK x y z" or "FAIL x y z" where x, y, and z are difference between selftest mode and normal mode. Test is passed when values are within acceptance limit values. Acceptance limits are provided via platform data. See chip spesifications for acceptance limits. If limits are not properly set, OK / FAIL decision is meaningless. However, userspace application can still make decision based on the numeric x, y, z values. Selftest is meant for HW diagnostic purposes. It is not meant to be called during normal use of the chip. It may cause false interrupt events. Selftest mode delays polling of the normal results but it doesn't cause wrong values. Chip must be in static state during selftest. Any acceration during the test causes most probably failure.

Originally the driver was only targeted to 12bits sensors. When support for 8bits sensors was added, some slight difference in the registers were overlooked. This should fix it, both for initialization, and for displaying the rate. Reported-by:

Add control of fan minimum turn-on output levels, decoupling it from the fan turn-off output level. Add control of rate of change of fan output level. These in turn allow lower turn-off rotor speed and smoother transitions for better thermal and acoustic control authority. Add support for constant fan speed and proportional-response operations modes. [akpm@linux-foundation.org: coding-style fixes] Signed-off-by:

This new revision of the IP adds some improvements to the MCI already present in several Atmel SOC. Some new registers are added and a particular way of handling DMA interaction lead to a new sequence in function call which is backward compatible: On MCI2, we must set the DMAEN bit to enable the DMA handshaking interface. This must happen before the data transfer command is sent. A new function is able to differentiate MCI2 code and is based on knowledge of processor id (cpu_is_xxx()). Signed-off-by:

Allow the use of another DMA controller driver in atmel-mci sd/mmc driver. This adds a generic dma_slave pointer to the mci platform structure where we can store DMA controller information. In atmel-mci we use information provided by this structure to initialize the driver (with new helper functions that are architecture dependant). This also adds at32/avr32 chip modifications to cope with this new access method. Signed-off-by:

Some people run general-purpose distribution kernels on netbooks with a card that is physically non-removable or logically non-removable (e.g. used for /home) and cannot be cleanly unmounted during suspend. Add a module parameter to set whether cards are assumed removable or non-removable, with the default set by CONFIG_MMC_UNSAFE_RESUME. In general, it is not possible to tell whether a card present in an MMC slot after resume is the same that was there before suspend. So there are two possible behaviours, each of which will cause data loss in some cases: CONFIG_MMC_UNSAFE_RESUME=n (default): Cards are assumed to be removed during suspend. Any filesystem on them must be unmounted before suspend; otherwise, buffered writes will be lost. CONFIG_MMC_UNSAFE_RESUME=y: Cards are assumed to remain present during suspend. They must not be swapped during suspend; otherwise, buffered writes will be flushed to the wrong card. Currently the choice is made at compile time and this allows that to be overridden at module load time. Signed-off-by:

Currently DaVinci EDMA driver supports multiple EDMA channel controller instances. edma_alloc_channel() api returns a 32 bit value which has the channel controller number in MSB and the EDMA channel number in LSB. The variables which store the value returned by edma_alloc_channel() have to be 32 bit wide now. Signed-off-by:

Rework the current CIS tuple parsing code, reusing the existing infrastructure and providing an easy way to add new CISTPL_FUNCE parsers by TPLFE_TYPE. Valid known CIS tuples are now silently queued for the SDIO function driver when not parsed/processed (-EILSEQ) by the SDIO core. Unknown CIS tuples (-ENOENT) are queued too for the SDIO function driver without aborting the initialization, but emit a warning in the kernel log. CISTPL_FUNCE tuples can be "whitelisted" now by adding a matching entry to the cis_tpl_funce_list table. Signed-off-by:

Rather than have the EDD depend on !ia64 (and assuming that only ia64, x86, x86_64 will be including this Kconfig), have EDD depend on the only arches which can support this code. This should allow all other arches to cleanly include the firmware Kconfig. Also simplify the x86 string used by FIRMWARE_MEMMAP to match EDD. Signed-off-by:

Recently, We marked strstrip() as must_check. because it was frequently misused and it should be checked. However, we found one exception. scsi/ipr.c intentionally ignore return value of strstrip. Because it wishes to keep the whitespace at the beginning. Thus we need to keep with and without checked whitespace trim function. This patch adds a new strim() and changes ipr.c to use it.
