Subject: [RFC PATCH 2/2] memory: samsung: exynos5422-dmc: Use delayed timer as default
Date: Fri,  3 Jul 2020 15:26:22 +0900	[thread overview]
Message-ID: <20200703062622.11773-3-cw00.choi@samsung.com> (raw)
In-Reply-To: <20200703062622.11773-1-cw00.choi@samsung.com>

Use delayed timer as default instead of deferrable timer
in order to monitor the DMC status regardless of CPU idle.
