Now that the video_device registration is tested using video_is_registered(), drivers don't need to initialize the video_device::minor field to -1 anymore. Remove those unneeded assignments.

Instead of using the minor number in kernel log messages, use the device node name as returned by the video_device_node_name() function. This makes debug, informational and error messages easier to understand for end users.

Fix all device drivers to use the video_drvdata function instead of maintaining a local list of minor to private data mappings. Call video_set_drvdata to register the driver private pointer when not already done. Where applicable, the local list of mappings is completely removed when it becomes unused.

Replace the video_is_unregistered function by a video_is_registered function. The V4L2_FL_UNREGISTERED flag is replaced by a V4L2_FL_REGISTERED flag. This change makes the video_is_registered function return coherent results when called on an initialize but not yet registered video_device instance. The function can now be used instead of checking video_device::minor. Signed-off-by:

This IR uses NEC protocol, with address=0x14. This keymap is similar to the existing Terratec Cinergy XS, except that: - it contains the full address/command code; - the Music button were mapped as KEY_RADIO; - some keycodes from the previous entry were wrong, IMHO. Signed-off-by: -

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.

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:
