From 072cd5f458d76b9e15d89ebdaea8b5cb1312eeef Mon Sep 17 00:00:00 2001 From: Fenglin Wu Date: Wed, 19 Nov 2025 14:06:43 +0800 Subject: [PATCH] leds: rgb: leds-qcom-lpg: Don't enable TRILED when configuring PWM The PWM signal from the LPG channel can be routed to PMIC GPIOs with proper GPIO configuration, and it is not necessary to enable the TRILED channel in that case. This also applies to the LPG channels that mapped to TRILED channels. Additionally, enabling the TRILED channel unnecessarily would cause a voltage increase in its power supply. Hence remove it.
