Input: synaptics-rmi4 - rename f30_data to gpio_data

2020-10-05T02:51:43Z

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.

Convert the RMI driver to use the standard mechanism for distributing IRQs to the various functions. Tested on: * S7300 (F11, F34, F54) * S7817 (F12, F34, F54) Signed-off-by: Nick Dyer Acked-by: Christopher Heiny Signed-off-by: Dmitry Torokhov

Input: synaptics-rmi4 - limit the range of what GPIOs are buttons

2017-10-27T22:15:59Z

By convention the first 6 bits of F30 Ctrl 2 and 3 are used to signify GPIOs which are connected to buttons. Additional GPIOs may be used as input GPIOs to signal the touch controller of some event (ie disable touchpad). These additional GPIOs may meet the criteria of a button in rmi_f30_is_valid_button() but should not be considered buttons. This patch limits the GPIOs which are mapped to buttons to just the first 6.

Input: synaptics-rmi4 - prevent null pointer dereference in f30

2017-03-10T18:22:53Z

If the platform data has f30_data.disable set, f30 in rmi_f30_config() might be null. Prevent a kernel oops by checking for non-null f30. Signed-off-by: Benjamin Tissoires Signed-off-by: Dmitry Torokhov

Input: rmi4 - f30: detect INPUT_PROP_BUTTONPAD from the button count

2017-03-01T18:01:56Z

INPUT_PROP_BUTTONPAD is currently only set through the platform data. The RMI4 header doc says that this property is there to force the buttonpad property, so we also need to detect it by looking at the exported buttons count.

Input: synaptics-rmi4 - forward upper mechanical buttons to PS/2 guest

2017-02-09T21:01:34Z

On the latest series of ThinkPads, the button events for the TrackPoint are reported through the touchpad itself as opposed to the TrackPoint device. In order to report these buttons properly, we need to forward them to the TrackPoint device and notify psmouse to send the button presses/releases.

Input: synaptics-rmi4 - clean up F30 implementation

2017-02-09T21:01:33Z

This patch does several cleanup changes to F30 code - switch to using BIT() macro - use DIV_ROUND_UP() where appropriate - factor out code setting up and reporting buttons - use single loop when reporting buttons: arithmetic is cheap compared to conditionals and associated branch misprediction.

Input: synaptics-rmi4 - store the attn data in the driver

2016-12-03T01:51:32Z

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 Reviewed-by: Andrew Duggan Signed-off-by: Dmitry Torokhov
