Subject: [PATCH v3 2/2] PM/devfreq: rk3399: get devfreq suspend frequency
Date: Mon, 7 Nov 2016 14:23:09 +0800 [thread overview]
Message-ID: <1478499789-21589-3-git-send-email-hl@rock-chips.com> (raw)
In-Reply-To: <1478499789-21589-1-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.
