Subject: [PATCH v2 1/2] devicetree: i2c-hid: Add Wacom digitizer + regulator support
Date: Wed, 30 Nov 2016 17:21:27 -0800 [thread overview]
Message-ID: <1480555288-142791-1-git-send-email-briannorris@chromium.org> (raw)
From: Caesar Wang <wxt@rock-chips.com>
Add a compatible string and regulator property for Wacom W9103
digitizer. Its VDD supply may need to be enabled before using it.

v1 was a few months back. I finally got around to rewriting it based on
DT binding feedback.
v2:
* add compatible property for wacom
* name the regulator property specifically (VDD)
