2019-06-25drm/mediatek: Use drm_atomic_helper_wait_for_fencesDaniel Vetter4-40/+3
If we use the gem fb helper as the prepare_fb hook, plus the drm_prime.c import helpers now automatically setting obj->resv, we can use the shared helpers to wait for fences instead of rolling our own. Note that this relies on mtk setting drm_fb->obj, which is already done in mtk_drm_framebuffer_init(). Aside: Probably can use the default commit_tail with this again, but I didn't check for that.

2019-06-04drm/mediatek: call mtk_dsi_stop() after mtk_drm_crtc_atomic_disable()Hsin-Yi Wang1-1/+9
mtk_dsi_stop() should be called after mtk_drm_crtc_atomic_disable(), which needs ovl irq for drm_crtc_wait_one_vblank(), since after mtk_dsi_stop() is called, ovl irq will be disabled. If drm_crtc_wait_one_vblank() is called after last irq, it will timeout with this message: "vblank wait timed out on crtc 0". This happens sometimes when turning off the screen. In drm_atomic_helper.c#disable_outputs(), the calling sequence when turning off the screen is: 1. mtk_dsi_encoder_disable() --> mtk_output_dsi_disable() --> mtk_dsi_stop(); /* sometimes make vblank timeout in atomic_disable */ --> mtk_dsi_poweroff(); 2. mtk_drm_crtc_atomic_disable() --> drm_crtc_wait_one_vblank(); ... --> mtk_dsi_ddp_stop() --> mtk_dsi_poweroff(); mtk_dsi_poweroff() has reference count design, change to make mtk_dsi_stop() called in mtk_dsi_poweroff() when refcount is 0.

Unbinding components (i.e. mtk_dsi and mtk_disp_ovl/rdma/color) will trigger master(mtk_drm)'s .unbind(), and currently mtk_drm's unbind won't actually unbind components. During the next bind, mtk_drm_kms_init() is called, and the components are added back. .unbind() should call mtk_drm_kms_deinit() to unbind components. And since component_master_del() in .remove() will trigger .unbind(), which will also unregister device, it's fine to remove original functions called here.

2019-05-20drm/fourcc: Pass the format_info pointer to drm_format_plane_cppMaxime Ripard1-1/+1
So far, the drm_format_plane_cpp function was operating on the format's fourcc and was doing a lookup to retrieve the drm_format_info structure and return the cpp. However, this is inefficient since in most cases, we will have the drm_format_info pointer already available so we shouldn't have to perform a new lookup. Some drm_fourcc functions also already operate on the drm_format_info pointer for that reason, so the API is quite inconsistent there. Let's follow the latter pattern and remove the extra lookup while being a bit more consistent. In order to be extra consistent, also rename that function to drm_format_info_plane_cpp and to a static function in the header to match the current policy.

2019-05-20drm: Remove users of drm_format_num_planesMaxime Ripard1-2/+4
drm_format_num_planes() is basically a lookup in the drm_format_info table plus an access to the num_planes field of the appropriate entry. Most drivers are using this function while having access to the entry already, which means that we will perform an unnecessary lookup. Removing the call to drm_format_num_planes is therefore more efficient. Some drivers will not have access to that entry in the function, but in this case the overhead is minimal (we just have to call drm_format_info() to perform the lookup) and we can even avoid multiple, inefficient lookups in some places that need multiple fields from the drm_format_info structure.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter6-6/+6
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

The fixes from Johan didn't get into linux-next, but they've been waiting for some time now and they are what's left of what subsystem maintainers didn't pick up. Summary: - Sync dtc with upstream version v1.4.7-14-gc86da84d30e4 - Work to get rid of direct accesses to struct device_node name and type pointers in preparation for removing them. New helpers for parsing DT cpu nodes and conversions to use the helpers. printk conversions to %pOFn for printing DT node names. Most went thru subystem trees, so this is the remainder. - Fixes to DT child node lookups to actually be restricted to child nodes instead of treewide. - Refactoring of dtb targets out of arch code.

2018-10-23drm/mediatek: fix OF sibling-node lookupJohan Hovold1-2/+3
Use the new of_get_compatible_child() helper to lookup the sibling instead of using of_find_compatible_node(), which searches the entire tree from a given start node and thus can return an unrelated (i.e. non-sibling) node. This also addresses a potential use-after-free (e.g. after probe deferral) as the tree-wide helper drops a reference to its first argument (i.e. the parent device node). While at it, also fix the related cec-node reference leak.
