From 684818189b04b095b34964ed4a3ea5249a840eab Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Mon, 17 Apr 2023 17:17:28 +0200 Subject: net: phy: phy_device: Call into the PHY driver to set LED brightness Linux LEDs can be software controlled via the brightness file in /sys. LED drivers need to implement a brightness_set function which the core will call. Implement an intermediary in phy_device, which will call into the phy driver if it implements the necessary function.
