From 7bce56fd73ee7264ed04418dab1719164e42f113 Mon Sep 17 00:00:00 2001 From: Stanislav Jakubek Date: Thu, 8 May 2025 16:11:27 +0200 Subject: [PATCH] ARM: dts: qcom: msm8226-motorola-falcon: limit TPS65132 to 5.4V After some digging in downstream sources, it was found that the TPS65132 outputs are fixed to +5.4V and -5.4V respectively. This is further confirmed on runtime through debugfs, the troubleshooting guide confirms this as well. Specify these limits as such.
