cpufreq: mediatek: Add support of cpufreq to MT2701/MT7623 SoC
MT2701/MT7623 is a 32-bit ARMv7 based quad-core (4 * Cortex-A7) with single cluster and this hardware is also compatible with the existing driver through enabling CPU frequency feature with operating-points-v2 bindings. Also, this driver actually supports all MediaTek SoCs, the Kconfig menu entry and file name itself should be updated with more generic name to drop "MT8173" Signed-off-by: Sean Wang <sean.wang@mediatek.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Rafael J.
