rust: platform: use generic device drvdata accessors

2025-07-08T22:04:33+00:00

Take advantage of the generic drvdata accessors of the generic Device type. While at it, use from_result() instead of match. Link: https://lore.kernel.org/r/20250621195118.124245-4-dakr@kernel.org Signed-off-by: Danilo Krummrich

rust: platform: impl TryFrom<&Device> for &platform::Device

2025-04-19T08:20:25+00:00

Implement TryFrom<&device::Device> for &Device. This allows us to get a &platform::Device from a generic &Device in a safe way; the conversion fails if the device' bus type does not match with the platform bus type.

rust: platform: add basic platform device / driver abstractions

2024-12-20T16:21:05+00:00

Implement the basic platform bus abstractions required to write a basic platform driver. This includes the following data structures: The `platform::Driver` trait represents the interface to the driver and provides `platform::Driver::probe` for the driver to implement. The `platform::Device` abstraction represents a `struct platform_device`. In order to provide the platform bus specific parts to a generic `driver::Registration` the `driver::RegistrationOps` trait is implemented by `platform::Adapter`.
