Subject: [PATCH v2 11/20] ARM: dts: imx6qdl-apalis: Add sleep state to can interfaces
Date: Wed, 31 Jul 2019 12:38:20 +0000 [thread overview]
Message-ID: <20190731123750.25670-12-philippe.schenker@toradex.com> (raw)
In-Reply-To: <20190731123750.25670-1-philippe.schenker@toradex.com>
This patch prepares the devicetree for the new Ixora V1.2 where we are
able to turn off the supply of the can transceiver. This implies to use
a sleep state on transmission pins in order to prevent backfeeding.
