Subject: [RFC 7/7] arm64: dts: imx8mq: Add cpu-sleep state with poke wake-up enabled
Date: Wed, 27 Mar 2019 13:21:18 +0000	[thread overview]
Message-ID: <1553692845-20983-8-git-send-email-abel.vesa@nxp.com> (raw)
In-Reply-To: <1553692845-20983-1-git-send-email-abel.vesa@nxp.com>

Add the idle state cpu-sleep to each core. This idle state
makes use of 'local-wakeup-poke' property which basically tells
the cpuidle-arm driver to enable the poking for this state.
