2013-01-04drm/exynos: correct some comments to abbreviation.Eunchul Kim3-3/+3
This patch cleanup corrects some comments to abbreviation. We would like to prevent it stands misunderstood. Signed-off-by: Eunchul Kim <chulspro.kim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
2013-01-04drm/exynos: fix build warning.Eunchul Kim1-1/+1
This patch fixes erroneous register read. reall function needs register base address + offset but exynos_drm_gsc module used only offset to read a register. so this patch uses gsc_read function instead of readl.

2013-01-04drm/exynos: consider both case of vflip and hflip.Eunchul Kim4-1/+5
This patch considers both case of vflip and hflip. If we want that the contents in buffer to be rotated to 180 degree, then we can use h,vflip or 180 degree. Changelog v2: - added EXYNOS_DRM_FLIP_BOTH enum value to avoid build warnning. Signed-off-by: Eunchul Kim <chulspro.kim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>

2013-01-04drm/exynos: change member variable name.Eunchul Kim5-14/+14
This patch change current command name from cmd to c_node. because we are using the member name, 'cmd', for command control ioctl in another structure. so, this patch changes it to c_node to avoid such confusing.

2013-01-04drm/exynos: consider buffer allocation without iommuInki Dae1-7/+48
This patch fixes the issue that when buffer allocation is requested without iommu, the allocation is failed. Without iommu, dma_alloc_attrs function allocates some memory region and returns cpu address so this patch makes the cpu address to be set to buf->kvaddr correctly. Changelog v2: - fix buffer free . Without iommu, dma_free_attrs function requires kernel space address as argument. So it changes the argument, buf->pages to buf->kvaddr.

2013-01-04drm/exynos: change file license to GPLInki Dae30-540/+120
This patch changes file license to GPL Most of exynos files had been copied from some random file and not updated correctly. So this patch corrects the file license. Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
2013-01-04drm/exynos: consider no iommu support to console framebufferInki Dae1-4/+18
This patch considers no iommu support to kernel space mapping of console framebuffer. Without iommu, we get physical address instead of device address after dma_alloc_attrs function is called. So we should consider the case without iommu when it maps console framebuffer with kernel space. Changelog v2: - calll vunmap function only with iommu support.
