From 4a9d72620058e95350258b4e0b006c8d3943d2ca Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sun, 14 Jun 2015 17:43:50 +0000 Subject: [PATCH] ar8216: Fix problem with AR8337 MAC swap handling AR8337 supports a configuration bit to swap MAC0 and MAC6. Currently this is set in general if an AR8337 is detected and causes issues with devices using an AR8334 (internally an AR8337, just less chip pins). And it might even cause issues with AR8337-based devices with different board designs. Swapping the MAC's however isn't needed for AR8337 in general. It's just needed in case of certain board designs (affected devices seem to be based on Atheros reference board AP135/136-010). Therefore this configuration bit should be moved to platform data. The patch includes the needed changes to the device initialization code of affected devices. Hopefully I didn't miss any ..
