Subject: [PATCH 11/22] ARM: dts: imx6: Add sleep state to can interfaces
Date: Tue, 30 Jul 2019 16:46:38 +0200	[thread overview]
Message-ID: <20190730144649.19022-12-dev@pschenker.ch> (raw)
In-Reply-To: <20190730144649.19022-1-dev@pschenker.ch>

From: Philippe Schenker <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.
