The timeout when waiting for the PRE safe window is rather short, as normally we would only need to wait a few dozen usecs for the problematic scanline region to pass and we don't want to spin too long in case something goes wrong. This however mixes badly with preemption, as we can easily get scheduled away from the CPU for a longer time than our timeout, in which case we would hit a spurious timeout and wrongly skip the PRE update. Instead of disabling preemption across the wait loop, potentially impacting the overall system latency, use a wait loop with a fixed max number of iterations, so time spent away from the CPU is not accounted against the timeout budget.

imx-drm doesn't mandate a modeset when the framebuffer modifier changes, but currently the tile prefetch and resolve (TPR) configuration of the PRE is only set up on the initial modeset. As the TPR configuration is double buffered, same as all the other PRE states, we can support dynamic reconfiguration of the buffer layout from one frame to another. As switching between (super-)tiled and linear prefetch needs to touch the CTRL register make sure to do the reconfiguration inside the safe window. Signed-off-by:

All Amlogic instances of the Synopsys HDMI controller need a power domain enabled. This is currently missing because the Amlogic HDMI driver directly pokes the power domain controller registers, which it should not do. Instead The HDMI controller should use the power controller.

Re-use the existing support for boot-up logos to draw a monochrome graphical logo in the DRM panic handler. When no suitable graphical logo is available, the code falls back to the ASCII art penguin logo. Note that all graphical boot-up logos are freed during late kernel initialization, hence a copy must be made for later use. Signed-off-by:

When CONFIG_FONTS ("Select compiled-in fonts") is not enabled, the user should not be asked about any fonts. However, when CONFIG_DRM_PANIC is enabled, the user is still asked about the Sparc console 12x22 and Terminus 16x32 fonts. Fix this by moving the "|| DRM_PANIC" to where it belongs.

No implementations of drm_plane_helper_funcs.get_scanout_buffer() fill in the optional drm_scanout_buffer.set_pixel() member. Hence the member may contain non-zero garbage, causing a crash when deferencing it during drm panic. Fix this by pre-initializing the drm_scanout_buffer object before calling drm_plane_helper_funcs.get_scanout_buffer().

With new connector model, tc358767 will not create the connector, when DRM_BRIDGE_ATTACH_NO_CONNECTOR is set and display-controller driver will rely on format negotiation to setup the encoder format. Add the missing bus format negotiation hooks in the drm_bridge_funcs to complete DRM_BRIDGE_ATTACH_NO_CONNECTOR support. Output format, for DPI/DSI to DP, is selected to MEDIA_BUS_FMT_RGB888_1X24 as default, keeping in mind what the older model used to support. Reported-by:
