From 8e1debd82466a3fe711784ab37e6b54e56011267 Mon Sep 17 00:00:00 2001 From: Sebastian Gottschall Date: Mon, 13 May 2024 17:22:25 +0300 Subject: [PATCH] wifi: ath10k: add LED and GPIO controlling support for various chipsets Adds LED and GPIO Control support for 988x, 9887, 9888, 99x0, 9984 based chipsets with on chipset connected led's using WMI Firmware API. The LED device will get available named as "ath10k-phyX" at sysfs and can be controlled with various triggers. Adds also debugfs interface for gpio control.
