Subject: [PATCH v2 5/5] ARM: dts: imx6dl-yapp4: Enable the MPR121 touchkey controller on Hydra
Date: Tue, 1 Oct 2019 16:29:40 +0200 [thread overview]
Message-ID: <1569940180-11417-6-git-send-email-michal.vokac@ysoft.com> (raw)
In-Reply-To: <1569940180-11417-1-git-send-email-michal.vokac@ysoft.com>
Add the touch keyboard present on Hydra board. The controller
is connected only using I2C lines. The interrupt line is not
available hence we use the polling mode.
Signed-off-by: Michal Vokáč <michal.vokac@ysoft.com>

Changes since v1:
- Use poll-interval property name instead of linux,poll-interval.
