The interrupt status registers should be read in row to avoid invalid data. Alter "read" method for both bus options to allow reading several registers in a row and make sure we read interrupt status registers properly. Read sequence saves 50% of bus transactions compared to single register reads. So use it also for the result registers, which are also located in a row. Also update copyright notice. Signed-off-by:

spi_write() requires use of DMA-safe (cacheline aligned) buffers. Also use the same buffers when reading data since to avoid extra locking and potential memory allocation in spi_write_then_read(). Acked-by:

The original license statement was confusing since it was unclear if the license was pure GPLv2 or GPLv2+ and did not match the license of the driver max11801_ts was derived from. The license is GPLv2+. Signed-off-by:

If kzalloc for kbc fails, then we have NULL pointer dereference while calling input_free_device(kbc->idev) in the error handling. So it is safer to always use the original name, input_dev. Signed-off-by:

Added USB device IDs for MacBookAir4,2 trackpad. Device constants were copied from the MacBookAir3,2 constants. The 4,2 device specification is reportedly unchanged from the 3,2 predecessor and seems to work well. Signed-off-by:

The analog joystick driver is written for x86 systems. This patch updates it to use the PIT_TICK_RATE value instead of CLOCK_TICK_RATE as they are equivalent on x86 and we want to deprecate the latter. Signed-off-by:

Input close or device disable should not interact with the exported gpiolib functionality. However that's the case. __ad7879_disable() clears the entire AD7879_REG_CTRL2, while it should just power down the ADC and its reference. Signed-off-by:

This patch enables fetching configuration data, which is normally provided via platform_data, from the device-tree instead. If the device is configured from device-tree data, the platform_data struct is not used, and button data needs to be allocated dynamically. Big part of this patch deals with confining pdata usage to the probe function, to make this possible. Signed-off-by:
