rust: regulator: add __rust_helper to helpers

2025-12-14T10:37:55+00:00

This is needed to inline these helpers into Rust code. Signed-off-by: Alice Ryhl Link: https://patch.msgid.link/20251202-define-rust-helper-v1-35-a2e13cbc17a6@google.com Reviewed-by: Gary Guo Reviewed-by: Boqun Feng Signed-off-by: Mark Brown

rust: regulator: add devm_enable and devm_enable_optional

2025-09-10T20:02:16+00:00

A lot of drivers only care about enabling the regulator for as long as the underlying Device is bound. This can be easily observed due to the extensive use of `devm_regulator_get_enable` and `devm_regulator_get_enable_optional` throughout the kernel. Therefore, make this helper available in Rust. Also add an example noting how it should be the default API unless the driver needs more fine-grained control over the regulator.

rust: regulator: add a bare minimum regulator abstraction

2025-07-15T14:07:40+00:00

Add a bare minimum regulator abstraction to be used by Rust drivers. This abstraction adds a small subset of the regulator API, which is thought to be sufficient for the drivers we have now. Regulators provide the power needed by many hardware blocks and thus are likely to be needed by a lot of drivers. It was tested on rk3588, where it was used to power up the "mali" regulator in order to power up the GPU.
