2011-08-26Input: wacom - advertise BTN_TOOL_PEN and BTN_STYLUS for PenPartnerJason Gerecke
The Wacom PenPartner should advertise its stylus tip and button in addition to the eraser tool. These are both physically present on the hardware, and emitted from 'wacom_penpartner_irq'.

2011-08-22Input: ad714x - read the interrupt status registers in a rowMichael Hennerich
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.

2011-08-22Input: ad714x - use DMA-safe buffers for spi_write()Dmitry Torokhov
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().

2011-08-11Input: tegra-kbc - correct call to input_free_deviceAxel Lin
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: Axel Lin <axel.lin@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2011-07-10Input: gpio_keys - add support for device-tree platform dataDavid Jander
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: David Jander <david@protonic.nl> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

Synaptics touchpads indicate via a capability bit when they perform reduced filtering on position data. In such a case, use a non-zero fuzz value.
