[PATCH v3 0/2] gpu: nova, nova-core: rename drivers and directory to follow kebab-case

[Cheng-Yang Chou]

Rename the nova-core and nova-drm drivers to follow kernel naming
conventions before these names become UAPI (e.g. exposed via
driver_override).

Changes in v3:
- Move drm::DriverInfo name/desc update from patch 1 to patch 2
  (Danilo Krummrich)
- Add kbuild composite object rule to nova/Makefile to produce
  nova-drm.ko (Danilo Krummrich)
- Add kbuild composite object rule to nova-core/Makefile to produce
  nova-core.ko (Danilo Krummrich)
- Fix debugfs directory name in nova_core.rs to "nova-core" to match
  module name
- Patch 2 has been reworked, no review tags carried over
- Link to v2:
  https://lore.kernel.org/r/20260316120820.2117081-1-yphbchou0911@gmail.com/

Changes in v2:
- Also fix nova-drm driver description from "Nvidia Graphics" to
  "NVIDIA Graphics and Compute" (John Hubbard)
- Rename drivers/gpu/drm/nova/ directory to drivers/gpu/drm/nova-drm/
  and nova.rs to nova_drm.rs to match the module name (Danilo Krummrich)
- Link to v1:
  https://lore.kernel.org/r/20260310062443.2763230-1-yphbchou0911@gmail.com/

[PATCH v3 1/2] gpu: nova, nova-core: Rename to kebab-case

[Cheng-Yang Chou]

Module names must follow kernel kebab-case convention before they
are exposed as UAPI via driver_override.

Rename the nova-drm module from "Nova" to "nova-drm" and the
nova-core module from "NovaCore" to "nova-core".

Update NOVA_CORE_MODULE_NAME to match the renamed nova-core module.

[PATCH v3 2/2] gpu: nova-drm: Rename nova to nova-drm

[Cheng-Yang Chou]

The .ko filenames must match the module names to ensure consistency
before these names are exposed as UAPI via driver_override.

Update nova/Makefile and nova-core/Makefile so that nova-drm.ko and
nova-core.ko are produced, matching the module names set in patch 1.

Update drm::DriverInfo with the correct driver name and vendor
description. Fix Kconfig help text for both drivers and the debugfs
directory name in nova-core to match the new module names.

Applied, thanks!

  Branch: drm-rust-next
  Tree:   https://gitlab.freedesktop.org/drm/rust/kernel.git

[1/2] gpu: nova, nova-core: Rename to kebab-case
      commit: 4f3491f6ec85
[2/2] gpu: nova: Use module names consistently
      commit: 8bfe9d72cf20

      [ Change commit subject to "gpu: nova: Use module names consistently";
        slightly adjust commit message. - Danilo ]

The patches will appear in the next linux-next integration (typically within 24
hours on weekdays).

The patches are queued up for the upcoming merge window for the next major
kernel release.
