2016-03-17Input: synaptics-rmi4 - remove check of Non-NULL arrayAndrew Duggan1-3/+2
Originally the irq_mask member of rmi_function was a pointer. Then it was switched to being a zero length array. However, the checks for a NULL pointer where not removed. Signed-off-by: Andrew Duggan <aduggan@synaptics.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2016-03-15Input: synaptics-rmi4 - using logical instead of bitwise ANDDan Carpenter1-2/+2

2016-03-10Input: synaptics-rmi4 - add support for 2D sensors and F11Andrew Duggan7-1/+1641
RMI4 currently defines two functions for reporting data for 2D sensors (F11 and F12). This patch adds the common functionality which is shared by devices with 2D reporting along with implementing functionality for F11.

2016-03-10Input: synaptics-rmi4 - add support for Synaptics RMI4 devicesAndrew Duggan7-0/+2277
Synaptics uses the Register Mapped Interface (RMI) protocol as a communications interface for their devices. This driver adds the core functionality needed to interface with RMI4 devices. RMI devices can be connected to the host via several transport protocols and can supports a wide variety of functionality defined by RMI functions. Support for transport protocols and RMI functions are implemented in individual drivers. The RMI4 core driver uses a bus architecture to facilitate the various combinations of transport and function drivers needed by a particular device.
