Hdmi monitor and dvi monitor can be distinguished with edid. This patch enables dvi mode if dvi monitor is connected and does not enable audio feature for dvi mode because dvi has no audio feature.

Later Exynos series from Exynos4X12 support HDMI version 1.4. We will distinguish to use which version via platform data. This patch supports only default features of HDMI version 1.4(The 3D, sound and etc don't support yet) Signed-off-by: NJoonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: NInki Dae <inki.dae@samsung.com> Signed-off-by: NKyungmin Park <kyungmin.park@samsung.com> Signed-off-by: NDave Airlie <airlied@redhat.com>

This patch is hdmi display support for exynos drm driver. There is already v4l2 based exynos hdmi driver in drivers/media/video/s5p-tv and some low level code is already in s5p-tv and even headers for register define are almost same. but in this patch, we decide not to consider separated common code with s5p-tv. Exynos HDMI is composed of 5 blocks, mixer, vp, hdmi, hdmiphy and ddc. 1. mixer. The piece of hardware responsible for mixing and blending multiple data inputs before passing it to an output device. The mixer is capable of handling up to three image layers. One is the output of VP. Other two are images in RGB format. The blending factor, and layers' priority are controlled by mixer's registers. The output is passed to HDMI. 2. vp (video processor). It is used for processing of NV12/NV21 data. An image stored in RAM is accessed by DMA. The output in YCbCr444 format is send to mixer. 3. hdmi. The piece of HW responsible for generation of HDMI packets. It takes pixel data from mixer and transforms it into data frames. The output is send to HDMIPHY interface. 4. hdmiphy. Physical interface for HDMI. Its duties are sending HDMI packets to HDMI connector. Basically, it contains a PLL that produces source clock for mixer, vp and hdmi. 5. ddc (display data channel). It is dedicated i2c channel to exchange display information as edid with display monitor. With plane support, exynos hdmi driver fully supports two mixer layes and vp layer. Also vp layer supports multi buffer plane pixel formats having non contigus memory spaces. In exynos drm driver, common drm_hdmi driver to interface with drm framework has opertion pointers for mixer and hdmi. this drm_hdmi driver is registered as sub driver of exynos_drm. hdmi has hdmiphy and ddc i2c clients and controls them. mixer controls all overlay layers in both mixer and vp. Vblank interrupts for hdmi are handled by mixer internally because drm framework cannot support multiple irq id. And pipe number is used to check which display device irq happens. History v2: this version - drm plane feature support to handle overlay layers. - multi buffer plane pixel format support for vp layer. - vp layer support RFCv1: original - at https://lkml.org/lkml/2011/11/4/164Signed-off-by: NSeung-Woo Kim <sw0312.kim@samsung.com> Signed-off-by: NInki Dae <inki.dae@samsung.com> Signed-off-by: NJoonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: NKyungmin Park <kyungmin.park@samsung.com>

Current version of the driver does not support HDMI features not present in DVI standard. Therefore DVI mode is used to keep compatibility with DVI devices.
