From 90fbec89be263a3838558c5b674f3c4072cc2f1d Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Sun, 10 Dec 2023 01:15:36 +0000 Subject: kernel: hack: support inverted LEDs on MaxLinear GPY211 PHY Add downstream DT property to setup the PHY LEDs of the MaxLinear GPY211 PHY in such way that the VDD of the LED is driven by the SoC pin rather than the GND (which is the default).
