2015-12-01drm/gma500: Add driver private mutex for the fault handlerDaniel Vetter1-0/+2
There's currently two places where the gma500 fault handler relies upon dev->struct_mutex: - To protect r->mappping - To make sure vm_insert_pfn isn't called concurrently (in which case the 2nd thread would get an error code). Everything else (specifically psb_gtt_pin) is already protected by some other locks. Hence just create a new driver-private mmap_mutex just for this function. With this gma500 is complete dev->struct_mutex free!

2015-10-06drm/irq: Use unsigned int pipe in public APIThierry Reding1-3/+3
This continues the pattern started in commit cc1ef118fc09 ("drm/irq: Make pipe unsigned and name consistent"). This is applied to the public APIs and driver callbacks, so pretty much all drivers need to be updated to match the new prototypes.

Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions The rest is general grab bag of fixes. So why part 1? well I have the exynos pull req which came in a bit late but was waiting for me to do something they shouldn't have and it looks fairly safe, and David Howells has some more header cleanups he'd like me to pull, that seem like a good idea, but I'd like to get this merge out of the way so -next dosen't get blocked."

2012-08-24gma500/cdv: Add eDP supportZhao Yakui1-0/+19
Introduce the eDP support into the driver. This has been reworked a bit because kernel driver proper uses encoder/connectors while the legacy Intel driver uses the old output stuff. It also diverges on the backlight handling. The legacy Intel driver adds a panel abstraction based upon the i915 one. It's only really used for backlight bits and we have a perfectly good backlight abstraction which can extend instead.
