Input: tsc200x - report proper input_dev name

2016-08-10T09:49:26+00:00

commit e9003c9cfaa17d26991688268b04244adb67ee2b upstream.

Passes input_id struct to the common probe function for the tsc200x drivers
instead of just the bustype.

This allows for the use of the product variable to set the input_dev->name
variable according to the type of touchscreen used. Note that when we
introduced support for TSC2004 we started calling everything TSC200X, so
let's keep this quirk.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

2015-11-14T05:41:14+00:00

Pull more input updates from Dmitry Torokhov:
 "An update to the tsc2005 driver that allows it to also support tsc2004
  (basically the same controller, but uses i2c instead of spi bus), and
  a couple of bug fixes"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: parkbd - drop bogus __init from parkbd_allocate_serio()
  Input: elantech - add Fujitsu Lifebook U745 to force crc_enabled
  Input: tsc2004 - add support for tsc2004
  Input: tsc200x-core - rename functions and variables
  Input: tsc2005 - separate SPI and core functions

Input: tsc200x-core - rename functions and variables

2015-11-03T22:54:01+00:00

The functions, variables, and defines of the new tsc200x-core.c are
renamed to tsc200x instead of tsc2005 avoid possible confusion.

Input: tsc2005 - separate SPI and core functions

2015-11-03T22:49:25+00:00

This patch separates the SPI functionality from core functionality
that overlaps with the tsc2004.

Prepares kernel for new tsc2004 driver without much redundant code.

spi: Drop owner assignment from spi_drivers

2015-10-28T01:30:17+00:00

An spi_driver does not need to set an owner, it will be populated by the
driver core.

Input: tsc2005 - convert to gpiod

2015-07-28T05:28:19+00:00

The GPIOD API can be used from boardcode, so that the DT check can be
removed. To avoid breaking existing boardcode, _optional() variant has been
chosen. For completely removing the DT check, the regulator has also been
made optional, so that it could be supplied from boardcode.

As a side-effect the patch fixes the after-probe reset GPIO state, so that
the device is not kept in reset state.

Input: tsc2005 - simplify drvdata acquisition

2015-07-28T05:28:18+00:00

Using dev_*_drvdata() instead of spi_*_drvdata() reduces lines of code and
prepares the driver for possible tsc2004 support, which is i2c based.

Input: tsc2005 - convert to regmap

2015-07-28T05:28:18+00:00

Convert driver so that it uses regmap instead of directly using
spi_transfer for all register accesses.

Input: tsc2005 - improve readability of register defines

2015-07-28T05:28:16+00:00

Improve defines for first control byte by removing 0x00 prefix (the defines
are for 8 bit values and not for 16 bit values) and expose register
structure by exposing the shift.

Input: of_touchscreen - switch to using device properties

2015-07-12T00:26:45+00:00

Let's switch form OF to device properties so that common parsing code could
work not only on device tree but also on ACPI-based platforms.
