drm/exynos: Stop using frame_vector helpers

2021-01-12T13:14:09Z

All we need are a pages array, pin_user_pages_fast can give us that directly. Plus this avoids the entire raw pfn side of get_vaddr_frames. Note that pin_user_pages_fast is a safe replacement despite the seeming lack of checking for vma->vm_flasg & (VM_IO | VM_PFNMAP). Such ptes are marked with pte_mkspecial (which pup_fast rejects in the fastpath), and only architectures supporting that support the pin_user_pages_fast fastpath.

drm/exynos: depend on COMMON_CLK to fix compile tests

2020-11-23T01:01:32Z

The Exynos DRM uses Common Clock Framework thus it cannot be built on platforms without it (e.g. compile test on MIPS with RALINK and SOC_RT305X): /usr/bin/mips-linux-gnu-ld: drivers/gpu/drm/exynos/exynos_mixer.o: in function `mixer_bind': exynos_mixer.c:(.text+0x958): undefined reference to `clk_set_parent' Reported-by: kernel test robot Signed-off-by: Krzysztof Kozlowski Signed-off-by: Inki Dae

drm/exynos: Rename Exynos to lowercase

2020-01-21T00:09:42Z

Fix up inconsistent usage of upper and lowercase letters in "Exynos" name. "EXYNOS" is not an abbreviation but a regular trademarked name. Therefore it should be written with lowercase letters starting with capital letter. The lowercase "Exynos" name is promoted by its manufacturer Samsung Electronics Co., Ltd., in advertisement materials and on website. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Inki Dae

drm/exynos: add CONFIG_MMU dependency

2019-08-02T06:28:47Z

Compile-testing this driver on a NOMMU configuration shows a link failure: drivers/gpu/drm/exynos/exynos_drm_gem.o: In function `exynos_drm_gem_fault': exynos_drm_gem.c:(.text+0x484): undefined reference to `vmf_insert_mixed' Add a CONFIG_MMU dependency to ensure we only enable this in configurations that build correctly. Many other drm drivers have the same dependency. It would be nice to make this work in MMU-less configurations, but evidently nobody has ever needed this so far.

drm/exynos: trigger build of all modules

2019-06-27T13:30:56Z

Add COMPILE_TEST dependency to force exynos driver to built for more than arm and to built modules that otherwise required other symbols to be de-selected. This will increase build coverage of the exynos driver thus allowing most trivial build errors to be detected/fixed early. This introduces one warning when built using sh: exynos7_drm_decon.c: In function ‘decon_remove’: exynos7_drm_decon.c:769:24: warning: unused variable ‘ctx’ struct decon_context *ctx = dev_get_drvdata(&pdev->dev); This is due to the definition of iounmap() in sh, and nothing that exynos driver can fix. Include fix of exynos build for alpha.

drm/exynos: Add driver for Exynos Scaler module

2018-05-09T23:53:23Z

Exynos Scaler is a hardware module, which processes graphic data fetched from memory and transfers the resultant dato another memory buffer. Graphics data can be up/down-scaled, rotated, flipped and converted color space. Scaler hardware modules are a part of Exynos5420 and newer Exynos SoCs.

drm/exynos: fimc: Convert driver to IPP v2 core API

2018-05-09T23:53:08Z

This patch adapts Exynos DRM FIMC driver to new IPP v2 core API. The side effect of this conversion is a switch to driver component API to register properly in the Exynos DRM core. Signed-off-by: Marek Szyprowski Merge conflict so merged manually. Signed-off-by: Inki Dae

drm/exynos: gsc: Convert driver to IPP v2 core API

2018-05-09T23:51:28Z

This patch adapts Exynos DRM GScaler driver to new IPP v2 core API. The side effect of this conversion is a switch to driver component API to register properly in the Exynos DRM core. During the conversion driver has been adapted to support more specific compatible strings to distinguish between Exynos5250 and Exynos5420 (different hardware limits). Support for Exynos5433 variant has been added too (different limits table, removed dependency on ARCH_EXYNOS5). Signed-off-by: Marek Szyprowski Tested-by: Hoegeun Kwon Signed-off-by: Inki Dae
