From 804f6acb7cea1ea5b3e0ded1bf037f9bf02f1124 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 9 Jul 2011 11:12:46 +0700 Subject: [PATCH] ath9k_hw: remove hardcoded PLL overrides for AR9280 Use the proper masks for the register instead. Fixes adding the (still unused) half/quarter PLL flags. Signed-off-by: Felix Fietkau Signed-off-by: John W.
