drm/amdgpu: fix DP mode validation

2016-05-12T19:03:49Z

Switch the order of the loops to walk the rates on the top so we exhaust all DP 1.1 rate/lane combinations before trying DP 1.2 rate/lane combos. This avoids selecting rates that are supported by the monitor, but not the connector leading to valid modes getting rejected. bug: https://bugs.freedesktop.org/show_bug.cgi?id=95206 Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/i915: Bail out of pipe config compute loop on LPT

2016-05-10T07:42:08Z

LPT is pch, so might run into the fdi bandwidth constraint (especially since it has only 2 lanes). But right now we just force pipe_bpp back to 24, resulting in a nice loop (which we bail out with a loud WARN_ON). Fix this.

drm/radeon: fix PLL sharing on DCE6.1 (v2)

2016-05-05T15:14:53Z

On DCE6.1 PPLL2 is exclusively available to UNIPHYA, so it should not be taken into consideration when looking for an already enabled PLL to be shared with other outputs. This fixes the broken VGA port (TRAVIS DP->VGA bridge) on my Richland based laptop, where the internal display is connected to UNIPHYA through a TRAVIS DP->LVDS bridge. Bug: https://bugs.freedesktop.org/show_bug.cgi?id=78987 v2: agd: add check in radeon_get_shared_nondp_ppll as well, drop extra parameter.

drm/radeon: fix DP link training issue with second 4K monitor

2016-05-05T15:14:18Z

There is an issue observed when we hotplug a second DP 4K monitor to the system. Sometimes, the link training fails for the second monitor after HPD interrupt generation. The issue happens when some queued or deferred transactions are already present on the AUX channel when we initiate a new transcation to (say) get DPCD or during link training. We set AUX_IGNORE_HPD_DISCON bit in the AUX_CONTROL register so that we can ignore any such deferred transactions when a new AUX transaction is initiated.

gpu: ipu-v3: Fix imx-ipuv3-crtc module autoloading

2016-05-05T00:34:52Z

If of_node is set before calling platform_device_add, the driver core will try to use of: modalias matching, which fails because the device tree nodes don't have a compatible property set. This patch fixes imx-ipuv3-crtc module autoloading by setting the of_node property only after the platform modalias is set.
