Subject: [PATCH v2 2/2] PM/devfreq: rk3399: set specific ddr frequency when stop ddr dvfs
Date: Thu,  3 Nov 2016 14:16:10 +0800	[thread overview]
Message-ID: <1478153770-8433-3-git-send-email-hl@rock-chips.com> (raw)
In-Reply-To: <1478153770-8433-1-git-send-email-hl@rock-chips.com>

We need ddr run a specific frequency when ddr dvfs stop
working. For example: if we enable two monitor, then we will
stop ddr dvfs, but we hope ddr can run in highest frequency
obviously.
