So far we always encountered socs with 2 output crtcs needing the driver to tell the hdmi block which output to connect to. But there also exist socs with only one crtc like the rk3228, rk3328 and rk3368. So adapt the register field to simply carry a negative value to signal that no output-switching is necessary. changes in v3: - fixed wording issue found by Robin Murphy Signed-off-by:

In some IP implementations the reading of the phy-type may be broken. One example are the Rockchip rk3228 and rk3328 socs that use a separate vendor-type phy from Innosilicon but still report the HDMI20_TX type. So allow the glue driver to force the vendor-phy for these cases. In the future it may be necessary to allow forcing other types, but for now we'll keep it simply to the case actually seen in the wild. changes in v3: - only allow forcing vendor type, as suggested by Laurent Signed-off-by:

Hardware allow to read the position in scanout buffer so we can use this information to make wait of vblank more accurate. Active area bounds (start, end, total height) have already been computed and written in ltdc registers, read them and get the current line position to compute vpos value. Signed-off-by:

This patch adds Olimex Ltd. LCD-OLinuXino bridge panel driver. The panel is used with different LCDs (currently from 480x272 to 1280x800). A small EEPROM chip is used for identification, which holds some factory data and timing requirements. Signed-off-by:

This panel is marketed as Banana Pi 7" LCD display. On the back is a sticker denoting the model name S070WV20-CT16. This is a 7" 800x480 panel connected through a 24-bit RGB interface. However the panel only does 262k colors. Depending on the variant, the PCB attached to the panel module either supports DSI, or DSI + 24-bit RGB. DSI is converted to 24-bit RGB via an onboard ICN6211 MIPI DSI - RGB bridge chip, then fed to the panel itself. Signed-off-by:

GPD has done it again, make a nice device (good), use way too generic DMI strings (bad) and use a portrait screen rotated 90 degrees (ugly). Because of the too generic DMI strings this entry is also doing bios-date matching, so the gpd_win2 data struct may very well need to be updated with some extra bios-dates in the future.

The hs_start interrupt on rk3188 fires at the start of a new frame, so serves essentially the same purpose as the dsp_hold_valid irq in checking when the last frame got delivered when going to standby. So define it to fix a hang on atomic_disable of the vop because the completion never really completed before. Fixes: 428e15cc ("drm/rockchip: vop: add rk3188 vop definitions") Signed-off-by:

This reverts commit 3510e7a7. 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. Signed-off-by:

The lcdif block is only powered on when display is active so plane updates when not enabled are not valid. Writing to an unpowered IP block is mostly ignored but can trigger bus errors on some chips. Prevent this situation by switching to drm_atomic_helper_commit_tail_rpm and having the drm core ensure atomic_plane_update is only called while the crtc is active. This avoids having to keep track of "enabled" bits inside the mxsfb driver. This also requires handling the vblank event for disable from mxsfb_pipe_disable. Signed-off-by:

LCDIF will repeatedly display data from CUR_BUF and set CUR_BUF to NEXT_BUF when done. Since we are only ever writing to NEXT_BUF the display will show an initial corrupt frame. Fix by writing the FB paddr to both CUR_BUF and NEXT_BUF when activating the CRTC. Signed-off-by:

The main axi clk is disabled at the end of mxsfb_crtc_mode_set_nofb and immediately reenabled in mxsfb_enable_controller. Avoid this by moving the handling of axi clk one level up to mxsfb_crtc_enable. Do the same for mxsfb_crtc_disable for symmetry. This shouldn't have any functional effect. Signed-off-by:

Implement vmap/vunmap so we can export dmabufs to other drivers, such as video4linux. Tested with a virtio-gpu / vivid (virtual capture driver) pipeline, where the vivid driver imports the dmabufs exported by virtio-gpu. Note that dma_buf_vmap() does its own vmap counting, so it's not needed to take care of it in the driver. Signed-off-by:

Currently, virtio_gpu_object_kmap() is only called by virtio_gpufb_create(), when a DRM framebuffer is created. Thus, instead of returning the vmap'ed address, emit a warning if virtio_gpu_object_kmap is called on an already mapped object. With this change, kmap/kunmap calls are now balanced. Signed-off-by:

The function ttm_bo_put releases a reference to a TTM buffer object. The function's name is more aligned to the Linux kernel convention of naming ref-counting function _get and _put. A call to ttm_bo_unref takes the address of the TTM BO object's pointer and clears the pointer's value to NULL. This is not necessary in most cases and sometimes even worked around by the calling code. A call to ttm_bo_put only releases the reference without clearing the pointer. The current behaviour of cleaning the pointer is kept in the calling code, but should be removed if not required in a later patch. Signed-off-by:
