The Samsung ATNA40YK20 panel is a 14" AMOLED eDP panel. It is similar to the ATNA33XC20 except that it is larger and has a different resolution.

The vmapped pages shall be pinned in memory and previously get/put_pages() were implicitly hard-pinning/unpinning the pages. This will no longer be the case with addition of memory shrinker because pages_use_count > 0 won't determine anymore whether pages are hard-pinned (they will be soft-pinned), while the new pages_pin_count will do the hard-pinning.

Implement a mock scheduler backend and add some basic test to exercise the core scheduler code paths. Mock backend (kind of like a very simple mock GPU) can either process jobs by tests manually advancing the "timeline" job at a time, or alternatively jobs can be configured with a time duration in which case they get completed asynchronously from the unit test code. Core scheduler classes are subclassed to support this mock implementation. The tests added are just a few simple submission patterns.

2025-03-23drm/v3d: Use V3D_SMS registers for power on/off and reset on V3D 7.xMaíra Canal4-0/+94
In addition to the standard reset controller, V3D 7.x requires configuring the V3D_SMS registers for proper power on/off and reset. Add the new registers to `v3d_regs.h` and ensure they are properly configured during device probing, removal, and reset. This change fixes GPU reset issues on the Raspberry Pi 5 (BCM2712). Without exposing these registers, a GPU reset causes the GPU to hang, stopping any further job execution and freezing the desktop GUI. The same issue occurs when unloading and loading the v3d driver.

In order to enforce per-SoC register rules, add per-compatible restrictions. For example, V3D 3.3 (used in brcm,7268-v3d) has a cache controller (GCA), which is not present in other V3D generations. Declaring these differences helps ensure the DTB accurately reflect the hardware design. The example was using an incorrect order for the register names.

2025-03-23drm/v3d: Associate a V3D tech revision to all supported devicesMaíra Canal7-84/+101
The V3D driver currently determines the GPU tech version (33, 41...) by reading a register. This approach has worked so far since this information wasn’t needed before powering on the GPU. V3D 7.1 introduces new registers that must be written to power on the GPU, requiring us to know the V3D version beforehand. To address this, associate each supported SoC with the corresponding VideoCore GPU version as part of the device data. To prevent possible mistakes, add an assertion to verify that the version specified in the device data matches the one reported by the hardware. If there is a mismatch, the kernel will trigger a warning. With the goal of maintaining consistency around the driver, use `enum v3d_gen` to assign values to `v3d->ver` and for comparisons with other V3D generations. Note that all mentions of unsupported or non-existing V3D generations (such as V3D 4.0) were removed by this commit and replaced with supported generations without functional changes.
