2019-07-17drm/sun4i: drop use of drmP.hSam Ravnborg
Drop use of the deprecated drmP.h header file. While touching the list of include file, use the typical order of the blocks: \#include <linux/*> \#include <video/*> \#include <drm/*> \#include "" Within each block, sort the files. Include necessary files to fix build after the drmP.h removal.

Our driver makes a typical use of CMA, with GEM object allocated as GEM CMA objects. Use DRM_GEM_CMA_VMAP_DRIVER_OPS to describe the ops instead of duplicating them. Because DRM_GEM_CMA_VMAP_DRIVER_OPS implements a gem_create_object op which sets per-object funcs (drm_cma_gem_default_funcs), we can also get rid of free_object_unlocked and gem_vm_ops, which are superseded by the object funcs.

The A23's display pipeline is similar to the A33.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter
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.

2018-11-01drm/sun4i: Use drm_fbdev_generic_setup()Noralf Trønnes
The CMA helper is already using the drm_fb_helper_generic_probe part of the generic fbdev emulation. This patch makes full use of the generic fbdev emulation by using its drm_client callbacks. This means that drm_mode_config_funcs->output_poll_changed and drm_driver->lastclose are now handled by the emulation code. Additionally fbdev unregister happens automatically on drm_dev_unregister(). The drm_fbdev_generic_setup() call is put after drm_dev_register() in the driver. This is done to highlight the fact that fbdev emulation is an internal client that makes use of the driver, it is not part of the driver as such. If fbdev setup fails, an error is printed, but the driver succeeds probing.

2018-09-27Revert "drm/sun4i: Remove R40 display pipeline compatibles"Chen-Yu Tsai
This reverts commit 3510e7a7f91088159bfc67e8abdc9f9e77d28870. During the 4.19 merge window for drm-misc, two patches critical to supporting the display pipeline on the Allwinner R40 SoC were missed. They were applied later but missed the merge window deadline. As a result 4.19-rc1 kernel would crash on the R40 when it couldn't parse the new device tree structure. We ended up removing support for the R40 display pipeline for 4.19. Since the missing patches are already merged for 4.20, we can now revert the commit that removed support.

2018-09-10drm/sun4i: Remove R40 display pipeline compatiblesChen-Yu Tsai
Two patches from the R40 display pipeline support series weren't applied with the rest of the series. When they did get applied, the -rc6 deadline for drm-misc-next had past, so they didn't get into 4.19-rc1 with the rest of the series. However, the two patches are crucial in the parsing of the R40's display pipeline graph in the device tree. Without them, the driver crashes because it can't follow the odd graph structure. This patch removes the R40 compatibles from the sun4i-drm driver, effectively disabling DRM support for the R40 for one release cycle. This will prevent the driver from crashing upon probing. The compatibles should be reinstated for the next release.

2017-10-17drm/sun4i: Implement endpoint parsing using kfifoMaxime Ripard
The commit da82b8785eeb ("drm/sun4i: add components in breadth first traversal order") implemented a breadth first traversal of our device tree nodes graph. However, it was relying on the kernel linked lists, and those are not really safe for addition. Indeed, in a single pipeline stage, your first stage (ie, the mixer or fronted) will be queued, and it will be the final iteration of that list as far as list_for_each_entry_safe is concerned. Then, during that final iteration, we'll queue another element (the TCON or the backend) that list_for_each_entry_safe will not account for, and we will leave the loop without having iterated over all the elements. And since we won't have built our components list properly, the DRM driver will be left non-functional. We can instead use a kfifo to queue and enqueue components in-order, as was the original intention. This also has the benefit of removing any dynamic allocation, making the error handling path simpler too. The only thing we're losing is the ability to tell whether an element has already been queued, but that was only needed to remove spurious logs, and therefore purely cosmetic. This means that this commit effectively reverses e8afb7b67fba ("drm/sun4i: don't add components that are already in the queue").

2017-10-16drm/sun4i: don't add components that are already in the queueChen-Yu Tsai
Even though the components framework can handle duplicate entries, the extra entries cause a lot more debug messages to be generated, which would be confusing to developers not familiar with our driver and the framework in general. Instead, we can scan the relatively small queue and check if the component to be added is already queued up. Since the display pipelines are symmetrical (not considering the third display pipeline on the A80), and we add components level by level, when we get to the second instance at the same level, any shared downstream components would already be in the queue.

2017-09-09drm/sun4i: call drm_vblank_init with correct number of crtcsChen-Yu Tsai
If we want to have vblank on both pipelines at the same time, we need to call drm_vblank_init with num_crtcs = 2. Instead, since the crtc init calls correctly set mode_config.num_crtc, we can move the drm_vblank_init call to after the crtc init code is called, which is the component bind part. Then we can just pass mode_config.num_crtc in.

2017-09-09drm/sun4i: add components in breadth first traversal orderChen-Yu Tsai
The encoder drivers use drm_of_find_possible_crtcs to get upstream crtcs from the device tree using of_graph. For the results to be correct, encoders must be probed/bound after _all_ crtcs have been created. The existing code uses a depth first recursive traversal of the of_graph, which means the encoders downstream of the TCON get add right after the first TCON. The second TCON or CRTC will never be properly associated with encoders connected to it. Other platforms, such as Rockchip, deal with this by probing all CRTCs first, then all subsequent components. This is easy to do since the CRTCs correspond to just one device node, and are the first nodes in the pipeline. However with Allwinner SoCs, the function of the CRTC is split between the display backend (DE 1.0) or mixer (DE 2.0), which does scan-out and compositing, and the TCON, which generates the display timing signals. Further complicating the process, there may be a Dynamic Range Controller between the backend and the TCON. Also, the backend is preceded by the frontend, with a Display Enhancement Unit possibly in between. In a dual display pipeline setup, both frontends can feed either backend, and both backends can feed either TCON. We want all components of the same type to be added before the next type in the pipeline. Fortunately, the pipelines are perfectly symmetric, i.e. components of the same type are at the same depth when counted from the frontend. The only exception is the third pipeline in the A80 SoC, which we do not support anyway. Hence we can use a breadth first search traversal order to add components. We do not need to check for duplicates. The component matching system handles this for us.
