Subject: [PATCH v4 2/2] dt-bindings: touchscreen: consolidate simple touch controller to trivial-touch.yaml
Date: Tue, 21 Oct 2025 16:19:18 -0400 [thread overview]
Message-ID: <20251021201924.2881098-2-Frank.Li@nxp.com> (raw)
In-Reply-To: <20251021201924.2881098-1-Frank.Li@nxp.com>
Move 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.

change in v4
- add Reviewed-by: Rob Herring review tags
- rebase to next since v2 already pickup.
change in v3
move more files into trivial-touch.yaml
don't add rob's review by because big change
