Subject: [PATCH] cpufreq: mediatek: raise proc/sram max voltage for MT8516
References: bsc#1012628
Patch-mainline: 6.3.2
Git-commit: d3296bb4cafd4bad4a5cf2eeab9d19cc94f9e30e
[ Upstream commit d3296bb4cafd4bad4a5cf2eeab9d19cc94f9e30e ]
Since the upper boundary of proc/sram voltage of MT8516 is 1300 mV,
which is greater than the value of MT2701 1150 mV, we fix it by adding
the corresponding platform data and specify proc/sram_max_volt to
support MT8516.
