Struct UnregisteredChip 

pub struct UnregisteredChip<'a, T: PwmOps> { /* private fields */ }

A wrapper around ARef<Chip<T>> that ensures that register can only be called once.

Implementations

impl<T: PwmOps> UnregisteredChip<'_, T>

pub fn register(self) -> Result<ARef<Chip<T>>>

Registers a PWM chip with the PWM subsystem.

Transfers its ownership to the devres framework, which ties its lifetime to the parent device. On unbind of the parent device, the devres entry will be dropped, automatically calling pwmchip_remove. This function should be called from the driver’s probe.

Methods from Deref<Target = Chip<T>>

pub fn num_channels(&self) -> u32

Gets the number of PWM channels (hardware PWMs) on this chip.

pub fn is_atomic(&self) -> bool

Returns true if the chip supports atomic operations for configuration.

pub fn device(&self) -> &Device

Returns a reference to the embedded struct device abstraction.

pub fn drvdata(&self) -> &T

Gets the typed driver specific data associated with this chip’s embedded device.

Trait Implementations

impl<T: PwmOps> Deref for UnregisteredChip<'_, T>

type Target = Chip<T>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
