* drm/omap: add common scaled modesRicardo Salveti de Araujo2012-08-17
| | | | | | | | | | | | The idea behind it is just to add more modes, and add them with reduced blanking, so we have more choices while probing the EDID. It tries to identify what would be the native mode for the monitor, and add the scaler modes that would be compatible with it, but with reduced blanking. With that it can get more compatible modes with OMAP pixel clock. Signed-off-by: Ricardo Salveti de Araujo <ricardo.salveti@canonical.com>

* Add omap drm display driverRob Clark2012-08-17
| | | | | | | | | | | | | | | A DSS based DRM display driver, which provides a plugin interface for 3d/2d accelerators to register. The core driver handles construction of CRTC/encoder/connectors to represent the hardware, and support KMS. This driver replaces omapfb. The omap drm driver allocates framebuffer memory and implements (with the help of drm_fb_helper) the legacy fbdev interface. The driver maps CRTCs to overlays, encoders to overlay-managers, and connectors to dssdev's.

* brcm80211: smac: resume transmit fifo upon receiving framesArend van Spriel2012-05-25
| | | | | | | | | | | | | | | | | | | | | | | | BugLink: http://bugs.launchpad.net/bugs/996109 commit badc4f07622f0f7093a201638f45e85765f1b5e4 upstream. There have been reports about not being able to use access-points on channel 12 and 13 or having connectivity issues when these channels were part of the selected regulatory domain. Upon switching to these channels the brcmsmac driver suspends the transmit dma fifos. This patch resumes them upon handing over the first received beacon to mac80211. This patch is to be applied to the stable tree for kernel versions 3.2 and 3.3.

Currently the module init function registers a platform_device and only then allocates its IRQ and I/O region. This allows allocation to race with the device's suspend() function. Instead, allocate resources in the platform driver's probe() function and free them in the remove() function. The module exit function removes the platform device before the character device that provides access to it. Change it to reverse the order of initialisation.

If the usermode app does an ioctl over this serial device by using TIOCMIWAIT, then the code will wait by setting the current task state to TASK_INTERRUPTIBLE and then calling schedule(). This will be woken up by the qt2_process_modem_status on URB completion when the port_extra->shadowMSR is set to the new modem status. However, this could result in a lost wakeup scenario due to a race in the logic in the qt2_ioctl(TIOCMIWAIT) loop and the URB completion for new modem status in qt2_process_modem_status. Due to this, the usermode app's task will continue to sleep despite a change in the modem status.

| * [media] [staging] lirc_serial: allocate irq at init timeJarod Wilson2011-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There's really no good reason not to just grab the desired IRQ at driver init time, instead of every time the lirc device node is accessed. This also improves the speed and reliability with which a serial transmitter can operate, as back-to-back transmission attempts (i.e., channel change to a multi-digit channel) don't have to spend time acquiring and then releasing the IRQ for every digit, sometimes multiple times, if lircd has been told to use the min_repeat parameter.

| * [media] lirc_zilog: fix spinning rx threadJarod Wilson2011-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were calling schedule_timeout with the rx thread's task state still at TASK_RUNNING, which it shouldn't be. Make sure we call set_current_state(TASK_INTERRUPTIBLE) *before* schedule_timeout, and we're all good here. I believe this problem was mistakenly introduced in commit 5bd6b0464b68d429bc8a3fe6595d19c39dfc4d95, and I'm not sure how I missed it before, as I swear I tested the patchset that was included in, but alas, stuff happens...

* | Staging: comedi: fix build breakages on some platformsGreg Kroah-Hartman2011-06-27
| | | | | | | | | | | | | | | | Some platforms do not have virt_to_bus(), so properly depend on CONFIG_VIRT_TO_BUS for the Comedi drivers that need this function. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
