Subject: [PATCH 6/6] PM / devfreq: Set the min_freq and max_freq of devfreq device
Date: Thu, 19 Nov 2015 17:17:50 +0900 [thread overview]
Message-ID: <1447921070-6045-7-git-send-email-cw00.choi@samsung.com> (raw)
In-Reply-To: <1447921070-6045-1-git-send-email-cw00.choi@samsung.com>
After probing the devfreq device driver, the value of both min_freq and
max_freq are zero(0). So, this patch initializes the 'min_freq' and 'max_freq'
field of devfreq device by using the freq_table array.
