Subject: [PATCH v2 2/2] devicetree: i2c-hid: Add reset property
Date:   Tue, 31 Oct 2017 11:03:16 +0800
Message-Id: <1509418996-25348-2-git-send-email-hl@rock-chips.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Document a "reset" and "assert-reset-us", it can be used for
driver control reset property. And reuse post-power-on-delay-ms
for deassert reset delay.
