Subject: [RFC PATCH 0/2] PM / devfreq: Add delayed timer for polling
Date: Fri,  3 Jul 2020 15:26:20 +0900	[thread overview]
Message-ID: <20200703062622.11773-1-cw00.choi@samsung.com> (raw)
In-Reply-To: CGME20200703061508epcas1p171aa3c0ab832b77e5837d8bd1e563742@epcas1p1.samsung.com

Add the delayed timer to devfreq framework in order to support
the periodical polling mode without stop caused by CPU idle state.
Some Non-CPU device must need to monitor the device status like
utilization regardless of CPU state.

- patch1 explains the detailed reason why the delayed timer is required.
- patch2 initializes that exynos5422-dmc device use delayed timer as default
instead of deferrable timer.
