Subject: [PATCH 3/3] ARM: dts: imx6qdl-colibri: use pull-down on wake-up pin
Date: Tue, 26 Jun 2018 16:52:43 +0200 [thread overview]
Message-ID: <20180626145243.24880-3-stefan@agner.ch> (raw)
In-Reply-To: <20180626145243.24880-1-stefan@agner.ch>
The wake-up pin is pulled low with 100kOhm on the carrier board.
The current configuration of 100kOhm pull-up caused lots of
interrupts, especially during boot up. Make sure the pin is at a
reasonable level at startup by pulling it low on SoC side too.
