2011-07-01OMAP: DSS2: remove update_mode from omapdssTomi Valkeinen
Remove the whole update_mode stuff from omapdss driver. If automatic update for manual update displays is needed, it's better implemented in higher layers. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-07-01OMAP: DSS2: OMAPFB: Implement auto-update modeTomi Valkeinen
Implement auto-update mode for manual-update displays. omapfb driver uses a delayed work to update the display with a constant rate. The update mode can be changed via OMAPFB_SET_UPDATE_MODE ioctl, which previously called omapdss but is now handled inside omapfb, and a new sysfs file, "update_mode". The update interval is by default 20 times per second, but can be changed via "auto_update_freq" module parameter. There is also a new module parameter "auto_update", which will make omapfb start manual update displays in auto-update mode. This auto-update mode can be used for testing if the userspace does not support manual update displays properly. However, it is a very inefficient solution, and should be considered more as a hack for testing than something that could be used as a long term solution.

2011-07-01OMAP: DSS2: OMAPFB: Add struct to store per-display dataTomi Valkeinen
Create a new struct omapfb_display_data to contain omapfb's private per-display data. Move the bpp override there. This struct will be used to hold auto/manual update state of a display in the following patches. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-07-01OMAP: DSS2: DSI: Change dummy macros to inline functionsTomi Valkeinen
Using empty macros for performance measurement functions when DSS DEBUG is not enabled causes an unused variable warning. Change the empty macros to empty inline functions to remove the warning. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
2011-07-01OMAP: DSS2: remove extra includes from include/video/omapdss.hTomi Valkeinen
omapdss.h included platform_device.h and atomic.h, neither of which is needed by omapdss.h. Remove those includes from omapdss.h, and fix the affected .c files which did not include platform_device.h even though they should. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2011-06-20drm/radeon/kms/atom: fix duallink on some early DCE3.2 cardsAlex Deucher
Certain revisions of the vbios on DCE3.2 cards have a bug in the transmitter control table which prevents duallink from being enabled properly on some cards. The action switch statement jumps to the wrong offset for the OUTPUT_ENABLE action. The fix is to use the ENABLE action rather than the OUTPUT_ENABLE action on the affected cards. In fixed version of the vbios, both actions jump to the same offset, so the change should be safe.

if_open() calls try_module_get(), and after an attempt to lock a mutex the if_open() function may return -ERESTARTSYS without putting the module. Then, when if_open() is executed again, try_module_get() is called making the reference counter of THIS_MODULE greater than one at successful exit from if_open(). The if_close() function puts the module only once, and as a result it can't be unloaded. This patch adds module_put call before the return from if_open().

2011-06-16tun: teach the tun/tap driver to support netpollNeil Horman
Commit 8d8fc29d02a33e4bd5f4fa47823c1fd386346093 changed the behavior of slave devices in regards to netpoll. Specifically it created a mutually exclusive relationship between being a slave and a netpoll-capable device. This creates problems for KVM because guests relied on needing netconsole active on a slave device to a bridge. Ideally libvirtd could just attach netconsole to the bridge device instead, but thats currently infeasible, because while the bridge device supports netpoll, it requires that all slave interface also support it, but the tun/tap driver currently does not. The most direct solution is to teach tun/tap to support netpoll, which is implemented by the patch below. I've not tested this yet, but its pretty straightforward.

2011-06-16dp83640: drop PHY status frames in the driver.Richard Cochran
The dp83640 PHY provides time stamp and other information via special PHY status frames. Previously, the driver decoded the frames and then let the network stack drop them. This works fine when the PTP messages come over UDP. However, when receiving PTP messages via L2 packets, this creates a problem. The status frames use the official PTP destination MAC address, and so they are delivered to user space along with the "real" frames, causing confusion for applications. This commit fixes the issue by simply dropping the PHY status frames in the driver. Signed-off-by: Richard Cochran <richard.cochran@omicron.at> Signed-off-by: David S.
