| * Input: synaptics-rmi4 - add support for F55 sensor tuningGuenter Roeck2016-11-221-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sensor tuning support is needed to determine the number of enabled tx and rx electrodes for use in F54 functions. The number of enabled electrodes is not identical to the total number of electrodes as reported with F55:Query0 and F55:Query1. It has to be calculated by analyzing F55:Ctrl1 (sensor receiver assignment) and F55:Ctrl2 (sensor transmitter assignment). Support for additional sensor tuning functions may be added later.

* Input: synaptics-rmi4 - do not check for NULL when calling of_node_put()Markus Elfring2016-07-261-4/+1
| | | | | | | | | The of_node_put() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
* Input: synaptics-rmi4 - use of_get_child_by_name() to fix refcountAndrew Duggan2016-07-141-2/+2
| | | | | | | | | | | Calling of_find_node_by_name() assumes that the caller has incremented the refcount of the of_node being passed in. Currently, the caller is not incrementing the refcount of the of_node which results in the node being prematurely freed when of_find_node_by_name() calls of_node_put() on it. Instead use of_get_child_by_name() which does not call put on the of_node. Signed-off-by: Andrew Duggan <aduggan@synaptics.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

* Input: synaptics-rmi4 - add support for Synaptics RMI4 devicesAndrew Duggan2016-03-101-0/+375
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.
