From 34764100393544b0b9dddf4019b30c178a704195 Mon Sep 17 00:00:00 2001 From: V Sowmya Date: Mon, 21 Jun 2021 08:59:43 +0530 Subject: mb/intel/adlrvp: Update the FIVR configurations This patch sets the optimized FIVR configuration for adlrvp cutomized based on the pnp measurements to achieve the better power savings in sleep states. * Enable the external V1p05, Vnn, VnnSx rails in S0i1, S0i2, S0i3, S3, S4, S5 states. * Update the supported voltage states. * Set the ICC max to 500mA for v1p05 and vnn.
