Subject: [PATCH v3 03/10] cpufreq: arm_big_little: invoke frequency-invariance setter function
Date: Thu, 27 Jul 2017 20:33:05 +0100 [thread overview]
Message-ID: <20170727193312.9849-4-dietmar.eggemann@arm.com> (raw)
In-Reply-To: <20170727193312.9849-1-dietmar.eggemann@arm.com>
Call the frequency-invariance setter function arch_set_freq_scale()
if the new frequency has been successfully set which is indicated by
bL_cpufreq_set_rate() returning 0.
