Subject: [PATCH v5 4/4] ARM: exynos: extend cpuidle support to midas boards
Date: Thu, 8 Feb 2018 11:01:37 +1100 [thread overview]
Message-ID: <20180208000137.11264-5-simon@lineageos.org> (raw)
In-Reply-To: <20180208000137.11264-1-simon@lineageos.org>
Exynos4412 can only use cpuidle when running under a compatible
bootloader/firmware. The midas family of boards, including trats2,
have such a firmware, so allow them to use cpuidle.
Leave the trats2 check there in order to preserve the ABI.
