2024-02-09drm/print: add drm_dbg_printer() for drm device specific printerJani Nikula2-0/+45
We've lacked a device specific debug printer. Add one. Take category into account too. __builtin_return_address(0) is inaccurate here, so don't use it. If necessary, we can later pass __func__ to drm_dbg_printer() by wrapping it inside a macro.

2024-02-09drm/print: make drm_err_printer() device specific by using drm_err()Jani Nikula4-8/+18
With few users for drm_err_printer(), it's still feasible to convert it to be device specific. Use drm_err() under the hood. While at it, make the prefix optional.

2024-02-07drm: xlnx: zynqmp_dpsub: Filter interrupts against maskAnatoliy Klymenko1-1/+8
Filter out status register against the interrupts' mask. Some events are being reported via DP status register, even if corresponding interrupts have been disabled. One instance of such event leads to generation of VBLANK when the driver is in DRM bridge mode, which in turn results in NULL pointer dereferencing. We should avoid processing such events in an interrupt handler context. This problem is less noticeable when the driver operates in DMA mode, as in this case we have DRM CRTC object instantiated and DRM framework simply discards unwanted VBLANKs in drm_handle_vblank().

2024-02-07drm: xlnx: zynqmp_dpsub: Make drm bridge discoverableAnatoliy Klymenko1-0/+1
ZynqMP DPSUB supports 2 input modes: DMA based and live video. In the first mode, the driver implements CRTC and DP encoder DRM bridge to model the complete display pipeline. In this case, DRM bridge is being directly instantiated within the driver, not using any bridge discovery mechanisms. In the live video input mode video signal is generated by FPGA fabric and passed into DPSUB over the connected bus. In this mode driver exposes the DP encoder as a DRM bridge, expecting external CRTC to discover it via drm_of_find_panel_or_bridge() or a similar call. This discovery relies on drm_bridge.of_node being properly set. Assign device OF node to the bridge prior to registering it. This will make said bridge discoverable by an external CRTC driver.
