kernel/linux.git/drivers/input/touchscreen/cyttsp_core.h, branch v6.3

Input: cyttsp - remove public header

2021-06-02T04:13:11+00:00

There is nothing in include/linux/input/cyttsp.h that might be of interes to the kernel at large, so let's move this information into the driver code and remove the header.

Input: cyttsp - obtain regulators

2021-05-26T23:59:00+00:00

The CYTTSP TMA340 chips have two supplies: VCPIN and VDD for analog and digital voltage respectively. Add some minimal code to obtain and enable these regulators if need be.

Input: cyttsp - drop the phys path

2021-04-10T07:46:07+00:00

When I test to use the CY8CTMA340 with PostmarketOS I don't have any problem whatsoever in dropping this phys path, it finds and uses the touchscreen just as well. I suppose it is because userspace is using modern input libraries. I challenge the maintainers to point out a valid and still used userspace that actually need this. I say we drop it.

Input: cyttsp - switch to using device properties

2016-01-27T22:32:48+00:00

Drop support for platform data passed via a C-structure and switch to device properties instead, which should make the driver compatible with all platforms: OF, ACPI and static boards. Static boards should use property sets to communicate device parameters to the driver. Signed-off-by: Oreste Salerno Acked-by: Rob Herring Signed-off-by: Dmitry Torokhov

Input: cyttsp4 - use 16bit address for I2C/SPI communication

2013-07-07T04:57:06+00:00

In TSG4, register map is 512bytes long and to access all of it, one bit from address byte is used (which bit to use differs for I2C and SPI); Since common code used for TSG3 and TSG4 for I2C, this parameter wrongly used as u8. TSG3 does not access beyond 255 bytes but TSG4 may. Tested-on:TMA3XX DVB && TMA4XX DVB Signed-off-by: Ferruh Yigit Acked-by: Javier Martinez Canillas Signed-off-by: Dmitry Torokhov

Input: cyttsp - I2C driver split into two modules

2013-07-01T04:24:16+00:00

Existing I2C code is for TrueTouch Gen3 devices TrueTouch Gen4 device is using same protocol, will split driver into two pieces to use common code with both drivers. Read/Write functions parameter list modified, since shared code will be used by two separate drivers and these drivers are not sharing same structs, parameters updated to use common structures.

Input: cyttsp - fix swapped mfg_stat and mfg_cmd registers

2013-06-06T05:46:37+00:00

The command and status register in the driver were swapped with respect to the order specified in the datasheet (CY8CTMA140). Confirmed with Cypress that the order in the datasheet is correct. Signed-off-by: Matthias Kaehlcke Acked-by: Javier Martinez Canillas Signed-off-by: Dmitry Torokhov
