From b9b8286e4a3d72353ee90181f10507e2dfb1fd2b Mon Sep 17 00:00:00 2001 From: Umang Chheda Date: Wed, 18 Oct 2023 18:14:15 +0530 Subject: [PATCH 2/2] PENDING: arm64: dts: qcs6490-rb3: Remove voltage voting for USB rails USB driver does not vote for voltage on hsphy and ssphy rails. Due to which the initial voltage set by bootloader is overridden by regulator framework with min voltage specified on regulator registration. Fix this temporarily by removing voltage voting support, which will prevent regulator framework overriding the voltage set by bootloader for QCS6490 RB3 Platform. This commit will be reverted once voltage voting support is added in USB driver.
