Subject: [PATCH v5 0/4] Add device tree support to the cyttsp driver

Implement a number of updates for the cyttsp driver to be able to parse generic
ACPI/of/static properties and drop support for platform data (no platform data
user is present in the kernel tree).

---
Changes in v5:
  Use custom devm action to turn off the chip
  Make reset gpio and touchscreen size properties optional
Changes in v4:
  Major rework based on Dmitry's review:
  - Use device_property_read() functions instead of of_property()
  - Use touchscreen_parse_properties to parse common properties
  - Drop support for platform data
  - Used devres managed allocations
Changes in v3:
  - Rework binding names and descriptions
Changes in v2:
  - Fix err_cast.cocci warning in patch 2/3
Oreste Salerno (4):
  Input: cyttsp - use devres managed resource allocations
  Input: cyttsp - check return value of input_mt_init_slots
  Input: cyttsp - switch to using device properties
  Input: cyttsp - perform hard reset of the chip during probe
