This adds support for TMP5P5 NT35596 1080x1920 video mode panel that can be found on some Asus Zenfone 2 Laser (Z00T) devices. This panel seems to only be found in this device and we have no straightforward way of actually getting the correct model number, as no schematics are released publicly. Signed-off-by:

Some memory is vmalloc'ed in the 'w100fb_save_vidmem' function and freed in the 'w100fb_restore_vidmem' function. (these functions are called respectively from the 'suspend' and the 'resume' functions) However, it is also freed in the 'remove' function. In order to avoid a potential double free, set the corresponding pointer to NULL once freed in the 'w100fb_restore_vidmem' function.

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.

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. Signed-off-by:

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. Signed-off-by:

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.
