Cover letter [PATCH v6 0/2] drm: Add DRM driver for GlandaGPU (VHDL soft-IP GPU)

This is v6 of the GlandaGPU DRM driver series [1][2][3][4][5]. It addresses review feedback from Thomas Zimmermann on v5.

GlandaGPU is a small VHDL soft-IP 2D display controller, currently targeting a Terasic DE10-Standard (Cyclone V SoC). This series has been tested against a QEMU digital twin and on real hardware.

Hardware/VHDL:   https://github.com/stiangglanda/GlandaGPU
QEMU fork:       https://github.com/stiangglanda/qemu-glandagpu
Userspace tests: https://github.com/stiangglanda/GlandaGPU-userspace-tests

Changes since v5:

driver core:
- Replace the custom glanda_crtc_atomic_flush() with drm_crtc_vblank_atomic_flush() (Thomas Zimmermann).

On the QEMU device ID: it's currently a placeholder from the experimental range, since I haven't submitted the QEMU patch to get an official one yet. Is that fine to merge as is, with a follow-up kernel patch once the official ID is assigned?
