Hello Imre, Miquel, Gregory, you are listed as some of the authors of commits for device tree for armada-385-linksys* devices. Do you still have access to such a device? This device should, according to DT, contain a LED pca9635 controller. I am searching for someone to test some patches I sent to linux-leds for this driver. If you are willing, it concers the top two patches of branch leds-pca963x-for-test of my kernel repository: https://git.kernel.org/pub/scm/linux/kernel/git/kabel/linux.git/log/?h=leds-pca963x-for-test Marek
