Merge branch 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-fixes
A couple of bios parser fixes (one for ancient chips, another for new ones - important in Optimus configs). Another to make sure KMS is enabled on certain Optimus configs, and a TTM failure path fix.
* 'drm-nouveau-next' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
drm/nouveau/ttm: prevent double-free in nouveau_sgdma_create_ttm() failure path
drm/nouveau/bios/init: fix thinko in INIT_CONFIGURE_MEM
drm/nouveau/kms: enable for non-vga pci classes
drm/nouveau/bios/init: stub opcode 0xaa

+* Samsung Image Rotator
+
+Required properties:
+ - compatible : value should be one of the following:
+ (a) "samsung,exynos4210-rotator" for Rotator IP in Exynos4210
+ (b) "samsung,exynos4212-rotator" for Rotator IP in Exynos4212/4412
+ (c) "samsung,exynos5250-rotator" for Rotator IP in Exynos5250
+
+ - reg : Physical base address of the IP registers and length of memory
+ mapped region.
+
+ - interrupts : Interrupt specifier for rotator interrupt, according to format
+ specific to interrupt parent.
+
+ - clocks : Clock specifier for rotator clock, according to generic clock
+ bindings. (See Documentation/devicetree/bindings/clock/exynos*.txt)
+
+ - clock-names : Names of clocks. For exynos rotator, it should be "rotator".
+
+Example:
+ rotator@12810000 {
+ compatible = "samsung,exynos4210-rotator";
+ reg = <0x12810000 0x1000>;
+ interrupts = <0 83 0>;
+ clocks = <&clock 278>;
+ clock-names = "rotator";
+ };
