Struct Config

pub struct Config<T>
where
    T: Default + ConfigOps,
{ /* private fields */ }

OPP configurations.

Rust abstraction for the C struct dev_pm_opp_config.

Examples

The following example demonstrates how to set OPP property-name configuration for a Device.

use kernel::device::Device;
use kernel::error::Result;
use kernel::opp::{Config, ConfigOps, ConfigToken};
use kernel::str::CString;
use kernel::types::ARef;
use kernel::macros::vtable;

#[derive(Default)]
struct Driver;

#[vtable]
impl ConfigOps for Driver {}

fn configure(dev: &ARef<Device>) -> Result<ConfigToken> {
    let name = CString::try_from_fmt(fmt!("{}", "slow"))?;

    // The OPP configuration is cleared once the [`ConfigToken`] goes out of scope.
    Config::<Driver>::new()
        .set_prop_name(name)?
        .set(dev)
}

Implementations

impl<T: ConfigOps + Default> Config<T>

pub fn new() -> Self

Creates a new instance of Config.

pub fn set_clk_names(self, names: KVec<CString>) -> Result<Self>

Initializes clock names.

pub fn set_prop_name(self, name: CString) -> Result<Self>

Initializes property name.

pub fn set_regulator_names(self, names: KVec<CString>) -> Result<Self>

Initializes regulator names.

pub fn set_required_dev(self, dev: ARef<Device>, index: u32) -> Result<Self>

Initializes required devices.

pub fn set_supported_hw(self, hw: KVec<u32>) -> Result<Self>

Initializes supported hardware.

pub fn set(self, dev: &Device) -> Result<ConfigToken>

Sets the configuration with the OPP core.

The returned ConfigToken will remove the configuration when dropped.

Trait Implementations

impl<T> Default for Config<T>

where T: Default + Default + ConfigOps,

fn default() -> Config<T>

Returns the “default value” for a type.
