Merge tag 'exynos-drm-next-for-v4.18' of... 

Merge tag 'exynos-drm-next-for-v4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

- Add S5PV210 FIMD variant support.

- 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,

    https://git.tizen.org/cgit/platform/kernel/linux-exynos/log/?h=tizen&qt=grep&q=ipp

    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";

	};
