2024-03-19drm: bridge: thc63lvd1024: Print error message when DT parsing failsLaurent Pinchart1-1/+4
Commit 00084f0c01bf ("drm: bridge: thc63lvd1024: Switch to use of_graph_get_remote_node()") simplified the thc63lvd1024 driver by replacing hand-rolled code with a helper function. While doing so, it created an error code path at probe time without any error message, potentially causing probe issues that get annoying to debug. Fix it by adding an error message.

2024-03-18drm/bridge: ite66121: Register HPD interrupt handler only when 'client->irq > 0'Sui Jingfeng1-7/+12
If a specific design doesn't wire IT66121's interrupt signal output pin up to the display controller side, then we should not register the interrupt handler. Such a decision is valid usage, as we can fall back to polling mode. So, don't make the assumption that a specific board always supports HPD. Carry out a sanity check on 'client->irq' before using it, fall back to polling mode if client->irq < 0 is true. Such a design increases the overall flexibility.

This IP block is found in the HDMI subsystem of the i.MX8MP SoC. It has a full timing generator and can switch between different video sources. On the i.MX8MP however the only supported source is the LCDIF. The block just needs to be powered up and told about the polarity of the video sync signals to act in bypass mode.
