This patch series adds support for the Novatek NT36xxx Series' In-Cell
touchscreen (integrated into the DriverIC).

This patch series has been tested against the following devices:
 - Sony Xperia 10        (SDM630 Ganges Kirin)
 - Sony Xperia 10 Plus   (SDM636 Ganges Mermaid)

Changes in v2:
- Fixed sparse warnings from lkp kernel test robot

Changes in v3 (as requested by Dmitry Torokhov):
- Using shorthand u16/u32 (sorry for the overlook!)
- Now using more input and touchscreen APIs
- Fixed useless workqueue involvements
- Removed useless locking
- Switched reads and writes to use regmap
- Moved header contents to nt36xxx.c
- Fixed reset gpio handling
- Other cleanups
- P.S.: Thanks, Dmitry!

Changes in v4:
- Fixed regmap read length for CRC_ERR_FLAG final check
- Fixed YAML binding, as requested by Krzysztof Kozlowski

Changes in v5:
- Replaced subsystem maintainer's name with .. mine,
  usage of additionalProperties to unevaluatedProperties
  and a typo fix for reset-gpios as per Rob Herring's review
- Changed compatible string as per Krzysztof K. request
- Renamed the novatek,nt36xxx.yaml file to just nt36xxx.yaml
  in order to now reflect the driver name instead of the DT
  compatible
- Fixed blank line at EOF

Changes in v6:
- Removed include of_gpio.h, added mod_devicetable.h and
  gpio/consumer.h
- Added kerneldoc to relevant functions/enum
- Used traditional patterns for error checking where possible
- Documented calls to usleep/msleep
- Using be16_to_cpu / get_unaligned_be16 where possible
- Added helper for CRC error check on retrieved buffer
- Decreased indentation in the CRC reboot recovery function
- Removed instances of error code sum
- Dropped all likely/unlikely optimization as per request
- Removed redundant reset_gpio checks
- Dropped of_match_ptr and ifdefs for CONFIG_OF

Changes in v7:
- Fixed typo in nt36xxx.c

Changes in v8:
- Fixed typo reset-gpio -> reset-gpios in dt-bindings

Changes in v9:
- Includes are now sorted
- Used proposed sizeof variable instead of sizeof type
- Fixed a return value check for common pattern
- Added NULL check to devm_kasprintf call
- Returning ret on probe function to be consistent
