From 121babfed84a0c6d7ebee4486db4fbd9a900d9f5 Mon Sep 17 00:00:00 2001 From: Akashdeep Kaur Date: Tue, 9 Sep 2025 10:11:06 +0530 Subject: [PATCH] arm64: dts: ti: k3-am62x-sk-common: Remove the unused cfg in USB1_DRVVBUS After the SoC has entered the DeepSleep low power mode, USB1 can be used to wakeup the SoC based on USB events triggered by USB devices. This requires that the pin corresponding to the Type-A connector remains pulled up even after the SoC has entered the DeepSleep low power mode. For that, either DeepSleep pullup configuration can be selected or the pin can have the same configuration that it had when SoC was in active mode. Remove the unnecessary DeepSleep state configuration from USB1_DRVBUS pin, as the DeepSleep control bit is not set and the active configuration is sufficient to keep the pin pulled up. This simplifies the setup and removes redundant configuration. This reverts commit 527f884d2d94981016e181dcbd4c4b5bf597c0ad.
