Subject: [PATCH v7] cpufreq: mediatek-hw: Add support for Mediatek cpufreq HW driver
Date: Thu, 10 Sep 2020 12:31:00 +0800 [thread overview]
Message-ID: <1599712262-8819-1-git-send-email-hector.yuan@mediatek.com> (raw)
The CPUfreq HW present in some Mediatek chipsets offloads the steps necessary for changing the frequency of CPUs.
The driver implements the cpufreq driver interface for this hardware engine.
This patch depends on the MT6779 DTS patch submitted by Hanks Chen
