2022-03-18media: Kconfig: cleanup VIDEO_DEV dependenciesMauro Carvalho Chehab1-1/+1
media Kconfig has two entries associated to V4L API: VIDEO_DEV and VIDEO_V4L2. On Kernel 2.6.x, there were two V4L APIs, each one with its own flag. VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core. while VIDEO_V4L2 where used to distinguish between drivers that implement the newer API and drivers that implemented the former one. With time, such meaning changed, specially after the removal of all V4L version 1 drivers. At the current implementation, VIDEO_DEV only does (1): it enables the media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenu but it doesn't affect anymore the V4L core drivers. The rationale is that the V4L2 core has a "soft" dependency at the I2C bus, and now requires to select a number of other Kconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEV In the past, merging them would be tricky, but it seems that it is now possible to merge those symbols, in order to simplify V4L dependencies. Let's keep VIDEO_DEV, as this one is used on some make *defconfig configurations.

This adds a hidden Kconfig symbol that enforces 'serio' to be enabled when RMI4-F03 is, which covers all cases.

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>

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 Roeck1-0/+1
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 ...")

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.

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.
