The 'exynos-drm-hdmi' driver makes use of s5p-tv platform devices. Therefore the driver should use the same platform data to prevent crashes caused by dereferencing incorrect types.

Changelog v3: make exynos_drm_display_power function use exynos_drm_best_encoder function instead of connector->encoder to get a valid encoder. connector->encoder could be NULL because with DRM_IOCTL_MODE_RMFB request, connector->encoder is NULL so fix this issue. Changelog v2: remove static prefix so that exynos_drm_best_encoder function could be called by other modules. Changelog v1: this patch fixes the issue that display power callback isn't called. with DRM_IOCTL_MODE_RMFB request, encoder->connector becomes NULL so display_ops->power_on() wouldn't be called so this patch makes exynos_drm_best_encoder function to be used to get a valid encoder of each connector.

when fb changing is requested, crtc's dpms mode should be on. if not on, return -EPERM so that the hardware can't be accessed. if user requesed dpms off and next SetCrtc with an another fb then the hardware can be accessed with dpms off to write overlay data onto some registers so this patch will prevent from accessing the hardware with dpms off.

this patch ensures that each plane connected to encoder is disabled when released, by adding disable callback function of encoder helper we had faced with one issue that invalid memory is accessed by dma once drm is released and then the dma is turned on again. actually, in our case, page fault was incurred with iommu. the reason is that a gem buffer accessed by the dma is also released once drm is released. so this patch would fix this issue ensuring the dma is disabled when released.

this patch adds buf_cnt variable in exynos_drm_fb structure and that means a buffer count to drm framebuffer and also adds two functions to get/set the buffer count from/to exynos_drm_fb structure. if pixel format is not DRM_FORMAT_NV12MT then it gets a buffer count to drm framebuffer refering to mode_cmd->handles and offsets. but when booted, the buffer count will always be 1 because pixel format of console framebuffer is RGB format.
