Pull the vblank event changes into a Linus master tree to make merging easier.
2013-05-22drm/imx: use drm_send_vblank_event() helperRob Clark
Also, slightly changes the behavior to always put the vblank irq, even if userspace did not request a vblank event. As far as I can tell, the previous code would leak a vblank irq refcnt if userspace requested a pageflip without event.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates (part 3) from Arnd Bergmann: "This is the third and smallest of the SoC specific updates. Changes include: - SMP support for the Xilinx zynq platform - Smaller imx changes - LPAE support for mvebu - Moving the orion5x, kirkwood, dove and mvebu platforms to a common "mbus" driver for their internal devices. It would be good to get feedback on the location of the "mbus" driver. Since this is used on multiple platforms may potentially get shared with other architectures (powerpc and arm64), it was moved to drivers/bus/.

The default configuration is pin2/pin3 for hsync/vsync. The VGA connector on i.MX53-QSB uses pin7/pin8, and the analog part of the DVI-I connector on MBa53 connects to pin4/pin6.

2012-09-21staging: drm/imx: add i.MX IPUv3 base driverSascha Hauer
The IPU is the Image Processing Unit found on i.MX51/53/6 SoCs. It features several units for image processing, this patch adds support for the units needed for Framebuffer support, namely: - Display Controller (dc) - Display Interface (di) - Display Multi Fifo Controller (dmfc) - Display Processor (dp) - Image DMA Controller (idmac) This patch is based on the Freescale driver, but follows a different approach. The Freescale code implements logical idmac channels and the handling of the subunits is hidden in common idmac code pathes in big switch/case statements. This patch instead just provides code and resource management for the different subunits. The user, in this case the framebuffer driver, decides how the different units play together. The IPU has other units missing in this patch: - CMOS Sensor Interface (csi) - Video Deinterlacer (vdi) - Sensor Multi FIFO Controler (smfc) - Image Converter (ic) - Image Rotator (irt) Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2012-09-21staging: drm/imx: Add parallel display supportSascha Hauer
This adds support for parallel displays for i.MX. It consists of a drm encoder/connector pair which eventually passes EDID data from the devicetree to the drm core. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
