Subject: [PATCH v5 2/3] dt-bindings: touchscreen: Add HY46XX bindings
Date: Sun, 11 Apr 2021 13:48:03 +0200 [thread overview]
Message-ID: <20210411114804.151754-3-giulio.benetti@benettiengineering.com> (raw)
In-Reply-To: <20210411114804.151754-1-giulio.benetti@benettiengineering.com>
This adds device tree bindings for the Hycon HY46XX touchscreen series.
Signed-off-by: Giulio Benetti <giulio.benetti@benettiengineering.com>
---
V1->V2:
As suggested by Rob Herring:
* fixed $id: address
* added "hycon," in front of every custom property
* changed all possible property to boolean type
* removed proximity-sensor-switch property since it's not handled in driver
V2->V3:
As suggested by Jonathan Neuschäfer:
* fixed some typo
* fixed description indentation
* improved boolean properties descriptions
* improved hycon,report-speed description
V3->V4:
* fixed binding compatible string in example as suggested by Jonathan Neuschäfer
V4->V5:
As suggested by Rob Herring:
* drop hycon- prefix from compatible
* use Hertz unit suffix for hycon,report-speed instead of u32
* set hycon,report-speed minimum to 1Hz, 0Hz make controller to do nothing
* change hycon,power-noise-enable property name to hycon,noise-filter-enable
* improve hycon,filter-data property description
* use generic touchscreen node name in example
