Changes in v7:
- Add RegulatorState::DISABLE_ON_DROP (Alice)
- Remove #[cfg(CONFIG_REGULATOR)] in lib.rs (if this is N we will use
the stubs)
- Add the bound on 'static directly on RegulatorState to avoid
repetition
- Removed the `data` member on the example (Alice)
- Removed the `mut` token from try_into_enabled() and
try_into_disabled() (Miguel & Intel bot)
- Link to v6: https://lore.kernel.org/r/20250627-topics-tyr-regulator-v6-0-1d015219b454@collabora.com
Changes in v6:
- Use ManuallyDrop<T> to avoid running the destructor in
try_into_enabled() and try_into_disabled(). This is the same strategy
that was being used successfully in the pre-typestate version of this
patch
- Link to v5: https://lore.kernel.org/r/20250623-topics-tyr-regulator-v5-0-99069658cb54@collabora.com
Changes in v5:
- Remove TryIntoEnabled and TryIntoDisabled traits (they were only
implemented for a single type anyways)
- Added regulator.rs to VOLTAGE AND CURRENT REGULATOR FRAMEWORK
- Applied the diff from Miguel Ojeda to format the docs
- Link to v4: https://lore.kernel.org/r/20250609-topics-tyr-regulator-v4-1-b4fdcf1385a7@collabora.com
Changes in v4:
- Rewrote the abstraction to use typestates as per the suggestions by
Benno and Alex.
- Introduced the `Dynamic` state.
- Added more examples.
- Fixed some broken docs.
- Link to v3: https://lore.kernel.org/r/20250513-topics-tyr-regulator-v3-1-4cc2704dfec6@collabora.com
Changes in v3:
- Rebased on rust-next
- Added examples to showcase the API
- Fixed some rendering issues in the docs
- Exposed {get|set}_voltage for both Regulator and EnabledRegulator
- Derived Clone, Copy, PartialEq and Eq for Microvolt
- Link to v2: https://lore.kernel.org/r/20250326-topics-tyr-regulator-v2-1-c0ea6a861be6@collabora.com
Resend v2:
- cc Regulator maintainers
Changes from v1:
- Rebased on rust-next
- Split the design into two types as suggested by Alice Ryhl.
- Modify the docs to highlight how users can use kernel::types::Either
or an enum to enable and disable the regulator at runtime.
