2024-02-21dt-bindings: display: Document Renesas RZ/G2L DU bindingsBiju Das
The RZ/G2L LCD controller is composed of Frame Compression Processor (FCPVD), Video Signal Processor (VSPD), and Display Unit (DU). The DU module supports the following hardware features − Display Parallel Interface (DPI) and MIPI LINK Video Interface − Display timing master − Generates video timings − Selecting the polarity of output DCLK, HSYNC, VSYNC, and DE − Supports Progressive − Input data format (from VSPD): RGB888, RGB666 − Output data format: same as Input data format − Supporting Full HD (1920 pixels x 1080 lines) for MIPI-DSI Output − Supporting WXGA (1280 pixels x 800 lines) for Parallel Output This patch documents the DU module found on RZ/G2L LCDC.

2024-02-19drm/meson: improve encoder probe / initialization error handlingMartin Blumenstingl
Rename meson_encoder_{cvbs,dsi,hdmi}_init() to meson_encoder_{cvbs,dsi,hdmi}_probe() so it's clear that these functions are used at probe time during driver initialization. Also switch all error prints inside those functions to use dev_err_probe() for consistency. This makes the code more straight forward to read and makes the error prints within those functions consistent (by logging all -EPROBE_DEFER with dev_dbg(), while actual errors are logged with dev_err() and get the error value printed).

This reverts commit 70e0d5550f5cec301ad116703b840a539fe985dc. The overridden mode fixes the panel glitching issue on mt8186 chromebook. However, it causes the internal display not working on mt8173 chromebook. Revert the overridden mode for now to let mt8173 have a functional display.

2024-02-14drm: ci: use clk_ignore_unused for apq8016Dmitry Baryshkov
If the ADV7511 bridge driver is compiled as a module, while DRM_MSM is built-in, the clk_disable_unused congests with the runtime PM handling of the DSI PHY for the clk_prepare_lock(). This causes apq8016 runner to fail without completing any jobs ([1]). Drop the BM_CMDLINE which duplicate the command line from the .baremetal-igt-arm64 clause and enforce the clk_ignore_unused kernelarg instead to make apq8016 runner work.

2024-02-14fbdev/efifb: Remove framebuffer relocation trackingThomas Zimmermann

2024-02-14firmware/sysfb: Update screen_info for relocated EFI framebuffersThomas Zimmermann
On ARM PCI systems, the PCI hierarchy might be reconfigured during boot and the firmware framebuffer might move as a result of that. The values in screen_info will then be invalid. Work around this problem by tracking the framebuffer's initial location before it get relocated; then fix the screen_info state between reloaction and creating the firmware framebuffer's device. This functionality has been lifted from efifb. See the commit message of commit 55d728a40d36 ("efi/fb: Avoid reconfiguration of BAR that covers the framebuffer") for more information.

Test if the firmware framebuffer's parent PCI device, if any, has been enabled. If not, the firmware framebuffer is most likely not working. Hence, do not create a device for the firmware framebuffer on disabled PCI devices. So far, efifb tracked the status of the PCI parent device internally and did not bind if it was disabled.

2024-02-14video: Add helpers for decoding screen_infoThomas Zimmermann
The plain values as stored in struct screen_info need to be decoded before being used. Add helpers that decode the type of video output and the framebuffer I/O aperture. Old or non-x86 systems may not set the type of video directly, but only indicate the presence by storing 0x01 in orig_video_isVGA. The decoding logic in screen_info_video_type() takes this into account. It then follows similar code in vgacon's vgacon_startup() to detect the video type from the given values. A call to screen_info_resources() returns all known resources of the given screen_info. The resources' values have been taken from existing code in vgacon and vga16fb. These drivers can later be converted to use the new interfaces. v2: * return ssize_t from screen_info_resources() * don't call __screen_info_has_lfb() unnecessarily Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240212090736.11464-2-tzimmermann@suse.de
