Boris Brezillion needs the gem lru fixes 379e8f1ca5e9 ("drm/gem: Make
the GEM LRU lock part of drm_device") backmerged for drm-misc-next.
That also means we need to sort out the rename conflict in panthor with
the fixup patch from Boris from drm-tip.

The exynos_gem->base.size argument is a size_t rather than an
unsigned long, so adapt the printk() format string accordingly:
In file included from drivers/gpu/drm/exynos/exynos_drm_gem.c:16:
drivers/gpu/drm/exynos/exynos_drm_gem.c: In function 'exynos_drm_alloc_buf':
drivers/gpu/drm/exynos/exynos_drm_gem.c:69:49: error: format '%lx' expects argument of type 'long unsigned int', but argument 6 has type 'size_t' {aka 'unsigned int'} [-Werror=format=]

70 | (unsigned long)exynos_gem->dma_addr, exynos_gem->base.size);

| size_t {aka unsigned int}
The dma_addr in the same line is already printed using a cast
to unsigned long, so change that similarly to use the correct
%pad format.

New feature and cleanup for Exynos fbdev - Move fbdev emulation to DRM client buffers . Reuses standard ADDFB2/GEM paths and simplifies cleanup. - Use DRM format helpers for geometry and size . Applies 4CC-based format/pitch/size calculation with stronger checks and PAGE_SIZE alignment. . Sets screen_size and fix.smem_len from actual allocated size. Exynos DRM internal cleanup - Adopt DRM core DMA tracking and drop redundant code . Removes private DMA tracking, exynos_drm_gem_prime_import(), and obsolete iommu_dma_init_domain() stub. - Reduce duplication and tighten local scope . Replaces MAX_FB_BUFFER with DRM_FORMAT_MAX_PLANES. . Drops redundant exynos_drm_gem.size and internalizes local-only helpers. Bug fix for Exynos fbdev behavior - Fix screen_buffer offset handling . Keeps screen_buffer at framebuffer base and avoids applying scanout offset. . Includes Fixes and stable Cc for backporting.

Replace the internal DRM framebuffer with a DRM client buffer. The client buffer allocates the DRM framebuffer on a file and also uses GEM object handles via the regular ADDFB2 interfaces. Using client-buffer interfaces unifies framebuffer allocation for DRM clients in user space and exynos' internal fbdev emulation. It also simplifies the clean-up side of the fbdev emulation.

Replace the geometry and size calculation in exynos' fbdev emulation with DRM format helpers. This consists of a 4CC lookup from the fbdev parameters, format lookup, pitch calculation and size calculation. Then allocate the GEM buffer object for the framebuffer memory from the calculated size. Mmap provides the allocated buffer to user space, so align the buffer size to PAGE_SIZE. Initialize the fields screen_size and fix.smem_len in struct fb_info from the size of the allocated buffer object. This is the real size and can differ from the requested size. v3: - add more error checks to geometry calculations Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Tested-by: Marek Szyprowski <m.szyprowski@samsung.com> Acked-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>

The screen_buffer field in struct fb_info contains the kernel address
of the first byte of framebuffer memory. Do not add the display offset.
This offset only describes scrolling during scanout.

Commit 1feda5eb77fc ("drm/exynos: Use selected dma_dev default iommu
domain instead of a fake one") removed the code around creating a
custom IOMMU domain, but forgot to remove the stub.
Remove the iommu_dma_init_domain() stub as the function is no longer
referenced, and was also made private to the IOMMU DMA code.
