Subject: [PATCH v3 2/4] thermal: power_allocator: change k_pu_ratio/k_po_ratio as percentage
Date: Wed, 6 Jan 2016 16:53:46 +0800 [thread overview]
Message-ID: <1452070428-2567-3-git-send-email-leo.yan@linaro.org> (raw)
In-Reply-To: <1452070428-2567-1-git-send-email-leo.yan@linaro.org>
Change k_pu_ratio/k_po_ratio as percentage value, so can set these
values from sys file nodes with high resolution.
