mb/google/nissa/uldren: Configure the external V1p05/Vnn/VnnSx
This patch configures external V1p05/Vnn/VnnSx rails for Uldren to follow best practices for power savings – untested though. * Enable the external V1p05, Vnn, VnnSx rails in S0i1, S0i2, S0i3, S3, S4, S5 , S0 states. * Set the supported voltage states. * Set the voltage for v1p05 and vnn. * Set the ICC max for v1p05 and vnn.
