tyr: remove impl Send/Sync for TyrData

2026-04-03T09:57:35+00:00

Now that clk implements Send and Sync, we no longer need to manually implement these traits for TyrData. Thus remove the implementations. The comment also mentions the regulator. However, the regulator had the traits added in commit 9a200cbdb543 ("rust: regulator: implement Send and Sync for Regulator"), which is already in mainline.

drm/tyr: Clarify driver/device type names

2026-03-02T16:35:19+00:00

Currently the `TyrDriver` struct implements both `platform::Driver` and `drm::Driver`. For clarity, split up these two roles: - Introduce `TyrPlatformDriverData` to implement `platform::Driver`, and - Introduce `TyrDrmDriver` to implement `drm::Driver`. Also rename other variables to reflect their roles in the DRM context: - Rename `TyrDevice` to `TyrDrmDevice` - Rename `TyrData` to `TyrDrmDeviceData` - Rename `File` to `TyrDrmFileData` - Rename `DrmFile` to `TyrDrmFile` No functional changes are intended.

drm/tyr: Use vertical style for imports

2026-02-24T07:21:26+00:00

Currently Tyr uses rustfmt style for imports, but the kernel uses a vertical layout that makes it easier to resolve conflicts and rebase. Import guidelines are documented here: https://docs.kernel.org/rust/coding-guidelines.html#imports Change all of Tyr's imports to use the vertical layout. This will ease the introduction of additional Tyr patches upstream. There should be no functional changes in this patch.

drm/tyr: suppress unread field warnings

2026-01-23T20:14:22+00:00

Currently the rust compiler warns that certain fields in the TyrDriver are 'never read'. The fields are needed, but they are not read directly, they are only written into an 'impl PinInit' that is returned by probe. When warnings are compiled as errors, these warnings prevent Tyr from building. Suppress the warnings by adding underscores to the problematic variables. This allows Tyr to build again.

drm/tyr: use read_poll_timeout

2026-01-20T08:51:53+00:00

The L2 power-on sequence and soft reset in Tyr previously relied on fixed sleeps followed by a single register check, since polling helpers were not available in Rust at the time. Now that read_poll_timeout() is available, poll the relevant registers until the hardware reports readiness or a timeout is reached. This avoids unnecessary delays on start-up.
