From da630738277ad5548d36eec864169c6d7de1056e Mon Sep 17 00:00:00 2001 From: Yidi Lin Date: Mon, 2 Oct 2023 15:54:33 +0800 Subject: mb/google/geralt: Update voltage mapping tables for RAM ID and LCMD ID The tolerance of ADC voltage table is too small. Update the table values accordring to the suggestion from the hardware team. The patch is prepared for the derived projects. There is no actual issue now.
