X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9b005036f8d070594fc7f3374f82c81f0a692918;p=openwrt%2Fstaging%2Fthess.git

ipq40xx: add LED functions for Google WiFi

Add LED function properties for the LED controller to avoid failing
driver probe with kernel 5.15.

While at it, also define the OpenWrt LED indicator patterns for this
device.

Ref commit 583ac0e11df7 ("mpc85xx: update lp5521 led-controller node for 5.10")

Google uses white for running and red for an issue
