The series allows setting the glitch threshold for the detected signal
from a DTS property instead of a hardcoded value.
In addition, I applied a patch that replaces opencoded masking and
shifting, with BIT(), GENMASK(), FIELD_GET() and FIELD_PREP() macros.

I didn’t remove patches:
 - 2/6 Input: imx6ul_tsc - use BIT, FIELD_{GET,PREP} and GENMASK macros
 - 1/6 Input: imx6ul_tsc - fix typo in register name
even though they were accepted, to avoid generating conflicts detected
by the kernel test robot.

Changes in v6:
- Rename the deglitch property from touchscreen-glitch-threshold-ns to
  debounce-delay-us.

Changes in v5:
- I didn’t remove patches:
   - 2/6 Input: imx6ul_tsc - use BIT, FIELD_{GET,PREP} and GENMASK macros
   - 1/6 Input: imx6ul_tsc - fix typo in register name
  even though they were accepted, to avoid generating conflicts detected
  by the kernel test robot.

Changes in v4:
- Adjust property description fsl,imx6ul-tsc.yaml following the
  suggestions of Conor Dooley and Frank Li.

Changes in v3:
- Remove the final part of the description that refers to
  implementation details in fsl,imx6ul-tsc.yaml.

Changes in v2:
- Replace patch ("dt-bindings: input: touchscreen: fsl,imx6ul-tsc: add
  fsl,glitch-threshold") with ("dt-bindings: touchscreen: add
  touchscreen-glitch-threshold-ns property"), making the previous property
  general by moving it to touchscreen.yaml.
- Rework "Input: imx6ul_tsc - set glitch threshold by DTS property" patch
  to match changes made to the DTS property.
- Move "Input: imx6ul_tsc - use BIT, FIELD_{GET,PREP} and GENMASK macros"
  patch right after the patch fixing the typo.
