This RFC series aims to extend cpu based scaling support to L3/DDR on SDM845 and SC7180 SoCs. Patches [1-3] - Blacklist SDM845 and SC7180 in cpufreq-dt-platdev Patches [5-7] - Hack in a way to add/remove multiple opp tables to a single device. I am yet to fix the debugfs to support multiple opp_tables per device but wanted to send what was working upstream to get an idea if multiple opp tables per device is a feature that will be useful upstream. Patches [9-10] - Add the cpu/cpu-ddr/cpu-l3 opp tables for SDM845 and SC7180 SoCs. v3: * Migrated to using Saravana's opp-kBps bindings [1] * Fixed some misc comments from Rajendra * Added support for SC7180 v2: * Incorporated Viresh's comments from: https://lore.kernel.org/lkml/20190410102429.r6j6brm5kspmqxc3@vireshk-i7/ https://lore.kernel.org/lkml/20190410112516.gnh77jcwawvld6et@vireshk-i7/ * Dropped cpufreq-map passive governor Git-branch: https://github.com/QuinAsura/linux/tree/lnext-012420 Some alternate ways of hosting the opp-tables: https://github.com/QuinAsura/linux/commit/50b92bfaadc8f9a0d1e12249646e018bd6d1a9d3 https://github.com/QuinAsura/linux/commit/3d23d1eefd16ae6d9e3ef91e93e78749d8844e98 Viresh didn't really like ^^ bindings and they dont really scale well. Just including them here for completeness.
