* drm/exynos: dsi: fix workaround for the legacy clock nameMarek Szyprowski2020-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit c0fd99d659ba5582e09625c7a985d63fc2ca74b5 ] Writing to the built-in strings arrays doesn't work if driver is loaded as kernel module. This is also considered as a bad pattern. Fix this by adding a call to clk_get() with legacy clock name. This fixes following kernel oops if driver is loaded as module: Unable to handle kernel paging request at virtual address bf047978 pgd = (ptrval) [bf047978] *pgd=59344811, *pte=5903c6df, *ppte=5903c65f Internal error: Oops: 80f [#1] SMP ARM Modules linked in: mc exynosdrm(+) analogix_dp rtc_s3c exynos_ppmu i2c_gpio CPU: 1 PID: 212 Comm: systemd-udevd Not tainted 5.6.0-rc2-next-20200219 #326 videodev: Linux video capture interface: v2.00 Hardware name: Samsung Exynos (Flattened Device Tree) PC is at exynos_dsi_probe+0x1f0/0x384 [exynosdrm] LR is at exynos_dsi_probe+0x1dc/0x384 [exynosdrm] ...

* mm: replace get_vaddr_frames() write/force parameters with gup_flagsLorenzo Stoakes2018-12-17
| | | | | | | | | | | | | | | | commit 7f23b3504a0df63b724180262c5f3f117f21bcae upstream. This removes the 'write' and 'force' from get_vaddr_frames() and replaces them with 'gup_flags' to make the use of FOLL_FORCE explicit in callers as use of this flag can result in surprising behaviour (and hence bugs) within the mm subsystem.

* drm/exynos: gem: Drop NONCONTIG flag for buffers allocated without IOMMUMarek Szyprowski2017-12-16
| | | | | | | | | | | | | | | | commit 120a264f9c2782682027d931d83dcbd22e01da80 upstream. When no IOMMU is available, all GEM buffers allocated by Exynos DRM driver are contiguous, because of the underlying dma_alloc_attrs() function provides only such buffers. In such case it makes no sense to keep BO_NONCONTIG flag for the allocated GEM buffers. This allows to avoid failures for buffer contiguity checks in the subsequent operations on GEM objects.

If we were to take the current subdrv pointer as the start of the list (as we would do if list_for_each_entry_reverse() was not a macro), we would iterate backwards over the &exynos_drm_subdrv_list anchor, which would be even worse. Instead, we need to use list_for_each_entry_continue_reverse() to go back over each subdrv that was successfully opened until the first entry.

* drm/exynos/gem: remove DMA-mapping hacks used for constructing page arrayMarek Szyprowski2015-11-03
| | | | | | | | | | | | | | Exynos GEM objects contains an array of pointers to the pages, which the allocated buffer consists of. Till now the code used some hacks (like relying on DMA-mapping internal structures or using ARM-specific dma_to_pfn helper) to build this array. This patch fixes this by adding proper call to dma_get_sgtable_attrs() and using the acquired scatter-list to construct needed array. This approach is more portable (work also for ARM64) and finally fixes the layering violation that was present in this code.

| * drm/<drivers>: Drop DRM_UNLOCKED from modeset driversDaniel Vetter2015-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just one special case (since i915 lost its ums code, yay): - radeon: Has slots for the old ums ioctls which don't have DRM_UNLOCKED, but all filled with drm_invalid_op. So ok to drop it everywhere. Every other kms driver just has DRM_UNLOCKED for all their ioctls, as they should. v2: admgpu happened, include that one too. And i915 lost its UMS support which means we can change all the i915 ioctls too. v3: Rebased on top of new vmwgfx DX interface extensions. v4: Rebase on top of render-node support in exynos.

| * drm/exynos: dp: remove suspend/resume functionsInki Dae2015-10-01
| | | | | | | | | | | | | | | | | | | | | | This patch removes unnecessary pm suspend/resume functions. All kms sub drivers will be controlled by top of Exynos drm driver and connector dpms so these sub drivers shouldn't have their own pm interfaces.
