This patch series aims to extend cpu based scaling support to L3/DDR on
SDM845 and SC7180 SoCs.

Patches [1-2] - Blacklist SDM845 and SC7180 in cpufreq-dt-platdev
Patches [3-5] - Update bw levels based on cpu frequency change

Based on the following series:

 * Pick up R-bs from Amit
 * Drop icc tag support/dt changes till the a consensus is achieved
 * Use dev_pm_opp_adjust_voltage instead [Viresh]
 * Drop dev_pm_opp_get_path_count [Saravana]
 * Rework dev_pm_opp_set_bw

 * Migrate to using Georgi's new bindings
 * Misc fixups based on Matthias comments
 * API fixups based on Bjorn's comments on v2
 * Picked up a few R-bs from Matthias

 * Migrated to using Saravana's opp-kBps bindings [1]
 * Fixed some misc comments from Rajendra
 * Added support for SC7180

 * Incorporated Viresh's comments from:
 * Dropped cpufreq-map passive governor

Sibi Sankar (5):
  cpufreq: blacklist SDM845 in cpufreq-dt-platdev
  cpufreq: blacklist SC7180 in cpufreq-dt-platdev
  OPP: Add and export helper to set bandwidth
  cpufreq: qcom: Update the bandwidth levels on frequency change
  cpufreq: qcom: Disable fast switch when scaling DDR/L3
