- Add IPP v2 framework.
   . it is a rewritten version of the Exynos mem-to-mem image processing
     framework which supprts color space conversion, image up/down-scaling
     and rotation. This new version replaces existing userspace API with
     new easy-to-use and simple ones so we have already applied the use of
     these API to real user, Tizen Platform[1], and also makes existing
     Scaler, FIMC, GScaler and Rotator drivers to use IPP v2 core API.
 
     And below are patch lists we have applied to a real user,

     TDM(Tizen Display Manager) is a Display HAL for Tizen platform.
     Ps. Only real user using IPP API is Tizen.

 - Two cleanups
   . One is to just remove mode_set callback from MIPI-DSI driver
     because drm_display_mode data is already available from crtc
     atomic state.
   . And other is to just use new return type, vm_fault_t
     for page fault handler.

* Samsung Exynos Image Scaler
Required properties:
- compatible : value should be one of the following:
(a) "samsung,exynos5420-scaler" for Scaler IP in Exynos5420
(b) "samsung,exynos5433-scaler" for Scaler IP in Exynos5433
- reg : Physical base address of the IP registers and length of memory
mapped region.
- interrupts : Interrupt specifier for scaler interrupt, according to format
specific to interrupt parent.
- clocks : Clock specifier for scaler clock, according to generic clock
bindings. (See Documentation/devicetree/bindings/clock/exynos*.txt)
- clock-names : Names of clocks. For exynos scaler, it should be "mscl"
on 5420 and "pclk", "aclk" and "aclk_xiu" on 5433.
Example:
scaler@12800000 {
compatible = "samsung,exynos5420-scaler";
reg = <0x12800000 0x1294>;
interrupts = <0 220 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clock CLK_MSCL0>;
clock-names = "mscl";
};
