2012-12-30drm: tegra: protect DC register access with mutexLucas Stach1-0/+13
Window properties are programmed through a shared aperture and have to happen atomically. Also we do the read-update-write dance on some of the shared regs. To make sure that different functions don't stumble over each other protect the register access with a mutex.

2012-11-28drm: tegra: Use framebuffer pitch as line strideThierry Reding1-1/+1
Instead of using the stride derived from the display mode, use the pitch associated with the currently active framebuffer. This fixes a bug where the LCD display content would be skewed when enabling HDMI with a video mode different from that of the LCD.

2012-11-20drm: Add NVIDIA Tegra20 supportThierry Reding1-0/+833
This commit adds a KMS driver for the Tegra20 SoC. This includes basic support for host1x and the two display controllers found on the Tegra20 SoC. Each display controller can drive a separate RGB/LVDS output.
