2020-10-04Input: synaptics-rmi4 - rename f30_data to gpio_dataVincent Huang1-5/+6
f30_data in rmi_device_platform_data could be also referenced by RMI function 3A, so rename it and the structure name to avoid confusion.

2016-12-02Input: synaptics-rmi4 - store the attn data in the driverBenjamin Tissoires1-3/+2
Now that we have a proper API to set the attention data, there is no point in keeping it in the transport driver. Signed-off-by: Benjamin Tissoires <[email protected]> Reviewed-by: Andrew Duggan <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>
2016-12-02Input: synaptics-rmi4 - allow to add attention dataBenjamin Tissoires1-0/+11
The HID implementation of RMI4 provides the data during the interrupt (in the input report). We need to provide a way for this transport driver to provide the attention data while calling an IRQ. We use a fifo in rmi_core to not lose any incoming event.

2016-11-30Input: synaptics-rmi4 - have only one struct platform dataBenjamin Tissoires1-2/+2
If struct rmi_device_platform_data contains pointers to other struct, it gets difficult to allocate a fixed size struct and copy it over between drivers. Change the pointers into a struct and change the code in rmi4 accordingly.

2016-11-22Input: synaptics-rmi4 - propagate correct number of rx and tx electrodes to F54Guenter Roeck1-0/+3
F54 diagnostics report functions provide data based on the number of enabled rx and tx electrodes, which is not identical to the number of electrodes reported with F54:Query0 and F54:Query1. Those values report the number of supported electrodes, not the number of enabled electrodes. The number of enabled electrodes can be determined by analyzing F55:Ctrl1 (sensor receiver assignment) and F55:Ctrl2 (sensor transmitter assignment). Propagate the number of enabled electrodes from F55 to F54 to avoid corrupted output if not all electrodes are enabled. Fixes: 3a762dbd5347 ("[media] Input: synaptics-rmi4 - add support for F54 ...")

gesture The rmi_f11 driver currently disables dribble packets and the palm detect gesture for all devices. This patch creates a parameter in the 2d sensor platform data for controlling this functionality on a per device basis.

2016-11-08Input: synaptics-rmi4 - move IRQ handling to rmi_driverBjorn Andersson1-3/+4
The attn IRQ is related to the chip, rather than the transport, so move all handling of interrupts to the core driver. This also makes sure that there are no races between interrupts and availability of the resources used by the core driver.

2016-03-10Input: synaptics-rmi4 - add support for Synaptics RMI4 devicesAndrew Duggan1-0/+209
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.
