Subject: [PATCH v2 2/2] memory: samsung: exynos5422-dmc: Use delayed timer as default
Date: Thu, 9 Jul 2020 14:45:04 +0900 [thread overview]
Message-ID: <20200709054504.656-3-cw00.choi@samsung.com> (raw)
In-Reply-To: <20200709054504.656-1-cw00.choi@samsung.com>
Use delayed timer as default instead of deferrable timer
in order to monitor the DMC status regardless of CPU idle.
