Subject: [PATCH v3 2/2] dt-bindings: touchscreen: consolidate simple touch controller to trivial-touch.yaml
Move ar1021.txt, azoteq,iqs5xx.yaml, himax,hx83112b.yaml,
hynitron,cstxxx.yaml, ilitek_ts_i2c.yaml, semtech,sx8654.yaml, ar1021.txt
to trivial-touch.yaml to consolidate simple touch yaml binding to one file.
Signed-off-by: Frank Li <Frank.Li@....com>

change in v3
move more files into trivial-touch.yaml
don't add rob's review by because big change
