Hi everyone,

This series is an attempt to get feedback on decoding D1 efuse speed bins
in the Sun50i H6 cpufreq driver, and turning the result into a meaningful
value that selects voltage ranges in an OPP table.

I want to make sure I get this right before sending in a v3 of the D1
cpufreq support series here

https://lore.kernel.org/linux-sunxi/20231218110543.64044-1-fusibrandon13@gmail.com/T/#t

which is currently stuck at

https://lore.kernel.org/linux-sunxi/aad8302d-a015-44ee-ad11-1a4c6e00074c@sholland.org/

Changes in v2:
- Make speed bin decoding generic in one patch and add D1 support in a
  separate patch
- Fix OPP voltage ranges to avoid stability issues

Brandon Cheo Fusi (3):
  cpufreq: sun50i: Refactor speed bin decoding
  cpufreq: sun50i: Add support for D1's speed bin decoding
  riscv: dts: allwinner: Fill in OPPs
