From 623e3a3963ea20881ba2d3096f873db81f1acdb7 Mon Sep 17 00:00:00 2001 From: Mark Hsieh Date: Tue, 6 Jun 2023 20:13:17 +0800 Subject: mb/google/nissa/var/joxer: Configure the external V1p05/Vnn/VnnSx rails This patch configures external V1p05/Vnn/VnnSx rails for Joxer to achieve the better power savings. * 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. Kit: 646929 - ADL N Platform Design Guide BUG=b:285477026 TEST=Verified all the UPD values are updated with these configs.
