2020-05-15drm/sun4i: mixer: Call of_dma_configure if there's an IOMMUMaxime Ripard
The main DRM device is actually a virtual device so it doesn't have the iommus property, which is instead on the DMA masters, in this case the mixers. Add a call to of_dma_configure with the mixers DT node but on the DRM virtual device to configure it in the same way than the mixers.

2020-05-14drm/vblank: remove outdated and noisy outputWolfram Sang
The R-Car DU driver calls drm_vblank_init via some helper functions in probe(). From what I checked, most drivers do this as well. I have a config now where DU always stays in deferred_probe state because of a missing dependency. This means that every time I rebind another driver like MMC, the vblank init message is displayed again when the DU driver is retried. Because the message doesn't really carry a useful information, I suggest to simply drop it.

2020-05-09drm/panel-simple: Support hpd-gpios for delaying prepare()Douglas Anderson
People use panel-simple when they have panels that are builtin to their device. In these cases the HPD (Hot Plug Detect) signal isn't really used for hotplugging devices but instead is used for power sequencing. Panel timing diagrams (especially for eDP panels) usually have the HPD signal in them and it acts as an indicator that the panel is ready for us to talk to it. Sometimes the HPD signal is hooked up to a normal GPIO on a system. In this case we need to poll it in the correct place to know that the panel is ready for us. In some system designs the right place for this is panel-simple. When adding this support, we'll account for the case that there might be a circular dependency between panel-simple and the provider of the GPIO. The case this was designed for was for the "ti-sn65dsi86" bridge chip. If HPD is hooked up to one of the GPIOs provided by the bridge chip then in our probe function we'll always get back -EPROBE_DEFER. Let's handle this by allowing this GPIO to show up late if we saw -EPROBE_DEFER during probe. NOTE: since the gpio_get_optional() is used, if the "hpd-gpios" isn't there our variable will just be NULL and we won't do anything in prepare().

Some memory is vmalloc'ed in the 'w100fb_save_vidmem' function and freed in the 'w100fb_restore_vidmem' function.

2020-05-05drm/mm: optimize rb_hole_addr rbtree searchNirmoy Das
Userspace can severely fragment rb_hole_addr rbtree by manipulating alignment while allocating buffers. Fragmented rb_hole_addr rbtree would result in large delays while allocating buffer object for a userspace application. It takes long time to find suitable hole because if we fail to find a suitable hole in the first attempt then we look for neighbouring nodes using rb_prev()/rb_next(). Traversing rbtree using rb_prev()/rb_next() can take really long time if the tree is fragmented. This patch improves searches in fragmented rb_hole_addr rbtree by modifying it to an augmented rbtree which will store an extra field in drm_mm_node, subtree_max_hole. Each drm_mm_node now stores maximum hole size for its subtree in drm_mm_node->subtree_max_hole. Using drm_mm_node->subtree_max_hole, it is possible to eliminate a complete subtree if that subtree is unable to serve a request hence reducing number of rb_prev()/rb_next() used. With this patch applied, 1 million bo allocs on amdgpu took ~8 sec, compared to 50k bo allocs which took 28 sec without it. partial test code: int test_fragmentation(void) { int i = 0; uint32_t minor_version; uint32_t major_version; struct amdgpu_bo_alloc_request request = {}; amdgpu_bo_handle vram_handle[MAX_ALLOC] = {}; amdgpu_device_handle device_handle; request.alloc_size = 4096; request.phys_alignment = 8192; request.preferred_heap = AMDGPU_GEM_DOMAIN_VRAM; int fd = open("/dev/dri/card0", O_RDWR | O_CLOEXEC); amdgpu_device_initialize(fd, &major_version, &minor_version, &device_handle); for (i = 0; i < MAX_ALLOC; i++) { amdgpu_bo_alloc(device_handle, &request, &vram_handle[i]); } for (i = 0; i < MAX_ALLOC; i++) amdgpu_bo_free(vram_handle[i]); return 0; } v2: Use RB_DECLARE_CALLBACKS_MAX to maintain subtree_max_hole v3: insert_hole_addr() should be static a function fix return value of next_hole_high_addr()/next_hole_low_addr() Reported-by: kbuild test robot <lkp@intel.com> v4: Fix commit message.

2020-05-05drm/bridge: chrontel-ch7033: Add a new driverLubomir Rintel
This is a driver for video encoder with VGA and DVI/HDMI outputs. There is no documentation for the chip -- the operation was guessed from what was sniffed on a Dell Wyse 3020 ThinOS terminal, the register names come from the ch7035 driver in Mediatek's GPL code dump. Only bare minimum is implemented -- no fancy stuff, such as scaling. That would only worsen our misery. We don't load the firmware and we don't need to even bother enabling the MCU. There are probably no distributable firmware images anyway. Tested with a handful of monitors ranging from 1024x768@75 to 1400x1050@60, with VGA as well as DVI.

2020-05-05drm/tidss: remove AM65x PG1 YUV erratum codeTomi Valkeinen
AM65x PG1 has a HW issue with YUV pixel formats, resulting in wrong colors on the screen. This issue is fixed in PG2 hardware. The driver currently has code to hide YUV pixel formats from the userspace. To support PG2, we would need to add code to detect the SoC version and hide the YUV formats based on that. However, as PG1 will be phased out and PG2 will be the main platform, a much simpler solution is just to drop the code in question. The downside is that the users will be able to use YUV formats on PG1, getting wrong colors on the screen. On the other hand, that may also be a plus, as the same applications will now work on PG1 and PG2, even if the colors are wrong on PG1.

2020-05-05drm/omap: change default signal polarities and drivesTomi Valkeinen
If the given videomode does not specify DISPLAY_FLAG_* for the specific signal property, the driver used a default value. These defaults were never thought through, as the expectation was that all the DISPLAY_FLAGS are always set explicitly. With DRM bridge and panel drivers this is not the case, and while that issue should be resolved in the future, it's still good to have sane signal defaults. This patch changes the defaults to what the hardware has as reset defaults. Also, based on my experience, I think they make sense and are more likely correct than the defaults without this patch.
