From df60c4102a40693b3796df04187996f2b929e138 Mon Sep 17 00:00:00 2001 From: Abhinav Saurabh Date: Thu, 9 Jan 2025 15:17:40 +0530 Subject: [PATCH] ARM: dts: msm: update dvdd initial voltage for tuna MTP & CDP Increase DVDD initial voltage from 1.06V to 1.09V. Also increase the min voltage voting to 1.09V for CDP and MTP platforms of Tuna. This is to avoid any voltage drop issue on the DVDD rail similar to Tuna QRD platform.
