This brings in version of sparse keymap code that uses managed memory.

Input: synaptics-rmi4 - select 'SERIO' when needed

2017-02-07T22:31:45Z

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.

Input: synaptics-rmi4 - use Kconfig "if" to express dependency

2016-12-29T18:10:26Z

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 Signed-off-by: Dmitry Torokhov

Input: synaptics-rmi4 - fix F03 build error when serio is module

2016-12-27T21:20:21Z

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 Reviewed-by: Guenter Roeck Signed-off-by: Dmitry Torokhov

Input: synaptics-rmi4 - propagate correct number of rx and tx electrodes to F54

2016-11-23T01:59:25Z

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 ...")

Input: synaptics-rmi4 - add support for F55 sensor tuning

2016-11-23T01:59:24Z

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.
