From d3cc7a15c1e1a04e8d561c0b05d176434142bf9a Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Fri, 15 Feb 2013 13:38:20 +0000 Subject: [PATCH] MIPS: ath79: add QCA955X specific glue to ath79_device_reset_{set, clear} commit 7d4c2af9bdbbe789fe4a93f32c5890d72cbf60a1 upstream. The ath79_device_reset_* are causing BUG when those are used on the QCA955x SoCs. The patch adds the required code to avoid that.
