From 4eb507901a3a671880f265f3ade9dafe3417ad7c Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sat, 9 Apr 2011 18:25:55 +0000 Subject: [PATCH] atheros: fix ath5k support on ar2315/2317 - Use physical addresses definition for AR2315 the same way as AR5312. Fixes ioremap - Fix dma mapping for AHB bus (only use the PCI DMA offset for PCI devices) Based on patches by Wojciech Dubowik SVN-Revision: 26554 --- .../atheros/patches-2.6.37/100-board.patch | 46 ++++++++++++------- .../patches-2.6.37/105-ar2315_pci.patch | 2 +- 2 files changed, 30 insertions(+), 18 deletions(-) diff --git a/target/linux/atheros/patches-2.6.37/100-board.patch b/target/linux/atheros/patches-2.6.37/100-board.patch index a30f5fe858..97d51f4798 100644 --- a/target/linux/atheros/patches-2.6.37/100-board.patch +++ b/target/linux/atheros/patches-2.6.37/100-board.patch @@ -552,7 +552,7 @@ +#endif /* __ASM_MACH_ATHEROS_CPU_FEATURE_OVERRIDES_H */ --- /dev/null +++ b/arch/mips/include/asm/mach-ar231x/dma-coherence.h -@@ -0,0 +1,64 @@ +@@ -0,0 +1,76 @@ +/* + * This file is subject to the terms and conditions of the GNU General Public + * License.
