2023-04-01Input: add a new Novatek NVT-ts driverHans de Goede1-0/+10
Add a new driver for the Novatek i2c touchscreen controller as found on the Acer Iconia One 7 B1-750 tablet. Unfortunately the touchscreen controller model-number is unknown. Even with the tablet opened up it is impossible to read the model-number. Android calls this a "NVT-ts" touchscreen, but that may apply to other Novatek controller models too. This appears to be the same controller as the one supported by https://github.com/advx9600/android/blob/master/touchscreen/NVTtouch_Android4.0/NVTtouch.c but unfortunately that does not give us a model-number either.

2022-11-22Input: stmpe-ts - drop obsolete dependency on COMPILE_TESTJean Delvare1-1/+1
Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

2022-03-18media: Kconfig: cleanup VIDEO_DEV dependenciesMauro Carvalho Chehab1-2/+2
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.

2021-10-16Input: ili210x - add ili251x firmware update supportMarek Vasut1-0/+1
The ili251x firmware can be updated, this is used when switching between different modes of operation of the touch surface, e.g. glove operation. This patch implements the firmware update mechanism triggered by a write into an sysfs attribute. The firmware itself is distributed as an intel hex file with non-standard types. The first two lines are of type 0xad, which indicates the start of DataFlash payload, that is always at address 0xf000 on the ili251x, so it can be dropped, and 0xac which indicates the position of firmware info in the Application payload, that is always at address 0x2020 on the ili251x and we do not care. The rest of the firmware is data of type 0x00, and we care about that. To convert the firmware hex file into something usable by the kernel, remove the first two lines and then use ihex2fw: $ tail -n +3 input.hex > temp.hex $ ./tools/firmware/ihex2fw temp.hex firmware/ilitek/ili251x.bin To trigger the firmware update, place firmware file ilitek/ili251x.bin into /lib/firmware/, write into firmware_update sysfs attribute and wait about 30-40 seconds. The firmware update is slow. Afterward, verify the firmware_version and mode sysfs attributes to check whether the firmware got updated and the controller switched back to application (AP) mode by reading out 'mode' attribute in sysfs. Note that the content of firmware_version, e.g. 0600.0005.abcd.aa04 can be matched to the content of the firmware hex file. The first four bytes, 0x06 0x00 0x00 0x05 can be found at ^:102030 00 05000006, the next four bytes 0xab 0xcd 0xaa 0x04 at ^:10F000 00 nnnnnnnn ABCDAA04. Note that the protocol differs considerably between the ili2xxx devices, this patch therefore implements this functionality only for ili251x that I can test.

Some devices outside of drivers/input/touchscreen/ can still make use of the touchscreen helper functions. Therefore, it was agreed in [1] to move them outside of drivers/input/touchscreen/ so that other devices can call them without INPUT_TOUCHSCREEN being set. As part of this change, 'of' is dropped from the filename because the helpers no longer actually use OF. No changes are made to the file contents whatsoever. Based on the feedback in [2], the corresponding binding documents (touchscreen.yaml and touchscreen.txt) are left in their original locations.

2019-01-14Input: raspberrypi-ts - fix link errorAnders Roxell1-1/+1
Fix link error when TOUCHSCREEN_RASPBERRYPI_FW is enabled as a module and the dependent module is built-in. The 'depends on RASPBERRYPI_FIRMWARE' by itself prevents the touchscreen driver from being built-in when the firmware is configured as a module. However, the '|| COMPILE_TEST' still allows it unless we explicitly prevent that configuration with '|| (RASPBERRYPI_FIRMWARE=n && COMPILE_TEST)'. ld: drivers/input/touchscreen/raspberrypi-ts.o: in function `rpi_ts_probe': raspberrypi-ts.c:(.text+0x3a8): undefined reference to `rpi_firmware_get' ld: raspberrypi-ts.c:(.text+0x3a8): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `rpi_firmware_get' ld: raspberrypi-ts.c:(.text+0x4c8): undefined reference to `rpi_firmware_property' ld: raspberrypi-ts.c:(.text+0x4c8): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `rpi_firmware_property' Rework so that TOUCHSCREEN_RASPBERRYPI_FW depends on RASPBERRYPI_FIRMWARE=n if COMPILE_TEST is enabled.

2018-12-21Input: add official Raspberry Pi's touchscreen driverNicolas Saenz Julienne1-0/+12
Add's support to Raspberry Pi's 7" Touch device. Instead of using a conventional bus all information is copied into a memory mapped area by RPi's firmware. Based on the driver found in RPi's kernel repository.

2018-06-10input: touchscreen: resistive-adc-touch: add generic resistive ADC touchscreenEugen Hristev1-0/+13
This adds a generic resistive touchscreen (GRTS) driver, which is based on an IIO device (an ADC). It must be connected to the channels of an ADC to receive touch data. Then it will feed the data into the input subsystem where it registers an input device. It uses an IIO callback buffer to register to the IIO device Some parts of this patch are based on initial original work by Mohamed Jamsheeth Hajanajubudeen and Bandaru Venkateswara Swamy Signed-off-by: Eugen Hristev <eugen.hristev@microchip.com> Acked-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

2018-05-09Input: add support for ChipOne icn8505 based touchscreensHans de Goede1-0/+11
The ChipOne icn8505 is an i2c capacitive touchscreen controller typically used in cheap x86 tablets, this commit adds a driver for it. Note the icn8505 is somewhat similar to the icn8318 and I started with modifying that driver to support both, but in the end the differences were too large and I decided to write a new driver instead.

2018-01-19Input: remove atmel-wm97xx touchscreen driverCorentin Labbe1-15/+0
Since AVR32 arch is gone, atmel-wm97xx driver is useless. In theory it could have been rewritten to work with AT91 devices, but the driver is from the platform data era, and a bit hard coded to work on AVR32 hardware variant of the AC97C peripheral, so let's remove it.
