Input: cyttsp - remove public header 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 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 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 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.

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

Input: add Cypress TTSP capacitive multi-touch screen support Cypress TrueTouch(tm) Standard Product controllers are found in a wide range of embedded devices. This driver add support for a variety of TTSP controllers. Since the hardware is capable of tracking identifiable contacts, multi-touch protocol type B (stateful) is used to report contact information. The driver is composed of a core driver that process the data sent by the contacts and a set of bus specific interface modules. This patch adds the base core TTSP driver.
