From 9ceeaf4c6cac6e5ff5a5225a5c9d13ba63d9c478 Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Thu, 11 May 2017 13:50:18 +0200 Subject: brcm63xx: switch to hardware led controllers Instead of bit banging SPI to talk to the GPIO chip, use the hardware led controllers intended for controlling the LEDs.
