2020-10-04Input: synaptics-rmi4 - add support for F3AVincent Huang
RMI4 F3A supports the touchpad GPIO function, it's designed to support more GPIOs and used on newer touchpads. This patch adds support of the touchpad buttons.

2017-02-07Input: synaptics-rmi4 - select 'SERIO' when neededArnd Bergmann
With CONFIG_SERIO=m, we get a build error for the rmi4-f03 driver, added in linux-4.10: warning: (HID_RMI) selects RMI4_F03 which has unmet direct dependencies (!UML && INPUT && RMI4_CORE && (SERIO=y || RMI4_CORE=SERIO)) drivers/input/built-in.o: In function `rmi_f03_attention': rmi_f03.c:(.text+0xcfe0): undefined reference to `serio_interrupt' rmi_f03.c:(.text+0xd055): undefined reference to `serio_interrupt' drivers/input/built-in.o: In function `rmi_f03_remove': rmi_f03.c:(.text+0xd115): undefined reference to `serio_unregister_port' drivers/input/built-in.o: In function `rmi_f03_probe': rmi_f03.c:(.text+0xd209): undefined reference to `__serio_register_port' An earlier patch tried to fix this, but missed the HID_RMI driver that does a 'select' on the F03 backend. This adds a hidden Kconfig symbol that enforces 'serio' to be enabled when RMI4-F03 is, which covers all cases.

2016-12-29Input: synaptics-rmi4 - use Kconfig "if" to express dependencyDmitry Torokhov
There is no need to repeat "depends on RMI4_CORE" on every bit of RMI4 support, we can guard all of them at once with "if RMI4_CORE". Also use tabs for F03 indentation. Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2016-12-27Input: synaptics-rmi4 - fix F03 build error when serio is moduleDmitry Torokhov
Since F03 is a boolean, "depends" on symbols that can be modules do not work quite right. We can enable F03 if SERIO is built-in or if both RMI core and SERIO core are modules. If SERIO core is module, but RMI is built-in, we'll get: drivers/built-in.o: In function `rmi_f03_attention': rmi_f03.c:(.text+0xf8ef8): undefined reference to `serio_interrupt' rmi_f03.c:(.text+0xf8fbd): undefined reference to `serio_interrupt' drivers/built-in.o: In function `rmi_f03_remove': rmi_f03.c:(.text+0xf9082): undefined reference to `serio_unregister_port' drivers/built-in.o: In function `rmi_f03_probe': rmi_f03.c:(.text+0xf9260): undefined reference to `__serio_register_port' Reported-by: Randy Dunlap <rdunlap@infradead.org> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

2016-11-22Input: synaptics-rmi4 - propagate correct number of rx and tx electrodes to F54Guenter Roeck
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 ...")

2016-11-22Input: synaptics-rmi4 - add support for F55 sensor tuningGuenter Roeck
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.

2016-09-19[media] Input: synaptics-rmi4: disallow impossible configurationArnd Bergmann
The newly added debug mode for the synaptics-rmi4 driver relies on the v4l2 interface and vb2_vmalloc, but those might be configured as loadable modules when the driver itself is built-in, resulting in a link failure: drivers/input/rmi4/rmi_core.o: In function `rmi_f54_remove': rmi_f54.c:(.text.rmi_f54_remove+0x14): undefined reference to `video_unregister_device' rmi_f54.c:(.text.rmi_f54_remove+0x20): undefined reference to `v4l2_device_unregister' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_s_input': rmi_f54.c:(.text.rmi_f54_vidioc_s_input+0x10): undefined reference to `video_devdata' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_g_input': rmi_f54.c:(.text.rmi_f54_vidioc_g_input+0x10): undefined reference to `video_devdata' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_fmt': rmi_f54.c:(.text.rmi_f54_vidioc_fmt+0x10): undefined reference to `video_devdata' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_enum_input': rmi_f54.c:(.text.rmi_f54_vidioc_enum_input+0x10): undefined reference to `video_devdata' drivers/input/rmi4/rmi_core.o: In function `rmi_f54_vidioc_querycap': ...

2016-03-10Input: synaptics-rmi4 - add support for Synaptics RMI4 devicesAndrew Duggan
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.
