From: Daniel Golle Date: Sun, 10 Dec 2023 01:15:36 +0000 (+0000) Subject: kernel: hack: support inverted LEDs on MaxLinear GPY211 PHY X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5c786dcb2b504e8260957592447e8088bcc35afa;p=openwrt%2Fstaging%2Fblocktrron.git 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).
