devm_* APIs are device managed and get freed automatically when the device detaches. Thus explicit freeing is not needed. This saves some code. Signed-off-by:

This patch fixes gem buffer allocation type checking. EXYNOS_BO_CONTIG has 0 so the checking should be fixed to 'if (!(flags & EXYNOS_BO_NONCONTIG))' Signed-off-by:

This patch fixes incorrect interrupt induced by m2m operation. the m2m operation calls s/w reset every frame but there is the case that the interrupt to m2m operation occures after s/w reset sometimes. So this patch makes dma and capture operations stop at s/w reset to avoid incorrect interrupt. Signed-off-by:

This patch removes color bar pattern register because we don't use the register anymore. because it doesn't support color bar feature for writeback operation. camera driver only supports color bar feature. but IPP doesn't support camera driver. Signed-off-by:

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. Signed-off-by:

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:

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. Signed-off-by:

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. Signed-off-by:

The idea here is to move to a finer grained reset. In some cases we may not need reset every block, and in other cases we may not need to re-init the entire asic. Reviewed-by:

Window properties are programmed through a shared aperture and have to happen atomically. Also we do the read-update-write dance on some of the shared regs. To make sure that different functions don't stumble over each other protect the register access with a mutex. Signed-off-by:
