* drm/exynos: wait for the completion of pending page flipInki Dae2013-05-23
| | | | | | | | | | | | | | This patch fixes the issue that drm_vblank_get() is failed.

* drm: prime: fix refcounting on the dmabuf import error pathImre Deak2013-04-30
| | | | | | | | | | | | | | | In commit be8a42ae60 we inroduced a refcount problem, where on the drm_gem_prime_fd_to_handle() error path we'll call dma_buf_put() for self imported dma buffers. Fix this by taking a reference on the dma buffer in the .gem_import hook instead of assuming the caller had taken one. Besides fixing the bug this is also more logical.

* drm/exynos: add device tree support for fimc ipp driverSylwester Nawrocki2013-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds OF initialization support for the FIMC driver. The binding documentation can be found at Documentation/devicetree/ bindings/media/samsung-fimc.txt. The syscon regmap interface is used to serialize access to the shared CAMBLK registers from within the V4L2 FIMC-IS and the DRM FIMC drivers. The DRM driver uses this interface for setting up the FIFO data link between FIMD and FIMC IP blocks, while the V4L2 one for setting up a data link between the camera ISP and FIMC for camera capture. The CAMBLK registers are not accessed any more through a statically mapped IO. Synchronized access to these registers is required for simultaneous operation of the camera ISP and the DRM IPP on Exynos4x12. The driver data and driver_ids static data structures are removed since Exynos4 is going to be a dt-only platform and there is currently no board file in mainline that defines platform data for the FIMC IPP, i.e. uses it. Camera input signal polarities are not currently parsed from the device tree.

* drm/exynos: rework fimc clocks handlingSylwester Nawrocki2013-04-29
| | | | | | | | | | | | | | | | The clocks handling is refactored and a "mux" clock handling is added to account for changes in the clocks driver. After switching to the common clock framework the sclk_fimc clock is now split into two clocks: a gate and a mux clock. In order to retain the exisiting functionality two additional consumer clocks are passed to the driver from device tree: "mux" and "parent". Then the driver sets "parent" clock as a parent clock of the "mux" clock. These two additional clocks are optional, and should go away when there is a standard way of setting up parent clocks on DT platforms.

* drm/exynos: prepare FIMD clocksVikas Sajjan2013-04-20
| | | | | | | | | | | | | | | While migrating to common clock framework (CCF), I found that the FIMD clocks were pulled down by the CCF. If CCF finds any clock(s) which has NOT been claimed by any of the drivers, then such clock(s) are PULLed low by CCF. Calling clk_prepare() for FIMD clocks fixes the issue. This patch also replaces clk_disable() with clk_unprepare() during exit, since clk_prepare() is called in fimd_probe().

* drm/exynos: change the method for getting the interruptVikas Sajjan2013-04-16
| | | | | | | | | | | | | | | | | | | | Replaces the "platform_get_resource() for IORESOURCE_IRQ" with platform_get_resource_byname(). Both in exynos4 and exynos5, FIMD IP has 3 interrupts in the order: "fifo", "vsync", and "lcd_sys". But The FIMD driver expects the "vsync" interrupt to be mentioned as the 1st parameter in the FIMD DT node. So to meet this expectation of the driver, the FIMD DT node was forced to be made by keeping "vsync" as the 1st paramter. For example in exynos4, the FIMD DT node has interrupt numbers mentioned as <11, 1> <11, 0> <11, 2> keeping "vsync" as the 1st paramter. This patch fixes the above mentioned "hack" of re-ordering of the FIMD interrupt numbers by getting interrupt resource of FIMD by using platform_get_resource_byname().

| * drm/exynos: add display-mode-check operation to exynos_mixer_ops structRahul Sharma2013-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the display mode check operation to exynos_mixer_ops in drm-common-hdmi. In Exynos SoCs, mixer IP can put certain restrictions on the proposed display modes. These restriction needs to be considered during mode negotiation, which happens immediately after edid parsing. Both, mixer check-mode and hdmi check-timing callbacks are called one after another and ANDed result is returned back.
