[PATCH v5 0/3] Add Novatek NT36xxx touchscreen driver

[kholk11]

From: AngeloGioacchino Del Regno <kholk11@xxxxxxxxx>

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
