2013-08-07drm/radeon: select audio dto based on encoder id for DCE3Alex Deucher1-3/+9
There are two audio dtos on radeon asics that you can select between. Normally, dto0 is used for hdmi and dto1 for DP, but it seems that the dto is somehow tied to the encoders on DCE3 asics. fixes: https://bugs.freedesktop.org/show_bug.cgi?id=67435 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org

2013-08-01PCI: mvebu: Disable prefetchable memory support in PCI-to-PCI bridgeThomas Petazzoni1-26/+1
The Marvell PCIe driver uses an emulated PCI-to-PCI bridge to be able to dynamically set up MBus address decoding windows for PCI I/O and memory regions depending on the PCI devices enumerated by Linux. However, this emulated PCI-to-PCI bridge logic makes the Linux PCI core believe that prefetchable memory regions are supported (because the registers are read/write), while in fact no adress decoding window is ever created for such regions. Since the Marvell MBus address decoding windows do not distinguish memory regions and prefetchable memory regions, this patch takes a simple approach: change the PCI-to-PCI bridge emulation to let the Linux PCI core know that we don't support prefetchable memory regions. To achieve this, we simply make the prefetchable memory base a read-only register that always returns 0. Reading/writing all the other prefetchable memory related registers has no effect. This problem was originally reported by Finn Hoffmann <finn@uni-bremen.de>, who couldn't get a RTL8111/8168B PCI NIC working on the NSA310 Kirkwood platform after updating to 3.11-rc. The problem was that the PCI-to-PCI bridge emulation was making the Linux PCI core believe that we support prefetchable memory, so the Linux PCI core was only filling the prefetchable memory base and limit registers, which does not lead to a MBus window being created. The below patch has been confirmed by Finn Hoffmann to fix his problem on Kirkwood, and has otherwise been successfully tested on the Armada XP GP platform with a e1000e PCIe NIC and a Marvell SATA PCIe card.

2013-08-01powerpc/windfarm: Fix noisy slots-fan on Xserve (rm31)Aaro Koskinen1-9/+9
slots-fan on G5 Xserve is always running at full speed with windfarm_rm31 driver, resulting in a very high acoustic noise level. It seems the fan parameters are incorrect, and have been copied from the Drive Bay fan (RPM, not present on rm31) of the legacy therm_pm72 driver. This patch changes the parameters to match the Slots fan (PWM) of therm_pm72. With the patch, slots-fan speed drops from 99% to 19% during normal use, and slots-temp settle to ~42'C.

2013-07-318139cp: Add dma_mapping_error checkingNeil Horman1-3/+45
Self explanitory dma_mapping_error addition to the 8139 driver, based on this: https://bugzilla.redhat.com/show_bug.cgi?id=947250 It showed several backtraces arising for dma_map_* usage without checking the return code on the mapping. Add the check and abort the rx/tx operation if its failed. Untested as I have no hardware and the reporter has wandered off, but seems pretty straightforward.

2013-07-31parisc: Fix interrupt routing for C8000 serial portsThomas Bogendoerfer2-13/+28
We can't use dev->mod_index for selecting the interrupt routing entry, because it's not an index into interrupt routing table. It will be even wrong on a machine with 2 CPUs (4 cores). But all needed information is contained in the PAT entries for the serial ports. mod[0] contains the iosapic address and mod_info has some indications for the interrupt input (at least it looks like it). This patch implements the searching for the right iosapic and uses this interrupt input information.
