From 930ed05ae6ff01045d2b5ee1b7752a96432b8826 Mon Sep 17 00:00:00 2001 From: priyankar Date: Tue, 1 Dec 2020 14:33:29 +0530 Subject: [PATCH] ARM: dts: msm: Increase max voltage of S11B regulator MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Change: Increase max voltage of S11B regulator to 2.04V. Reason: BT and WLAN vote for S11B first followed by camera driver. As the max limit set by BT and WLAN is 1.88V, later on when camera tries to vote for same regulator it fails. As min voltage required by camera is 1.952V which is greater than max limit of BT and WLAN so camera vote cant be allowed. note: At the time of BU, camera was voting for some lower voltage thats why this issue is not seen at that time. Fix: PMIC team suggested to increase max limit for BT and WLAN as 2.04 V. The regulator S11B’s supported voltage range is min: 1.7V – max: 2.04V.
