Expand description
A structure encapsulating a peripheral should implement this trait.
Required Associated Types§
type RegisterType
Required Methods§
Sourcefn get_registers(&self) -> &Self::RegisterType
fn get_registers(&self) -> &Self::RegisterType
How to get a reference to the physical hardware registers (the MMIO struct).
Sourcefn get_clock(&self) -> &C
fn get_clock(&self) -> &C
Which clock feeds this peripheral.
For peripherals with no clock, use
&::kernel::platform::chip::NO_CLOCK_CONTROL
.
Sourcefn before_peripheral_access(&self, _: &C, _: &Self::RegisterType)
fn before_peripheral_access(&self, _: &C, _: &Self::RegisterType)
Called before peripheral access.
Responsible for ensure the peripheral can be safely accessed, e.g. that its clock is powered on.
Sourcefn after_peripheral_access(&self, _: &C, _: &Self::RegisterType)
fn after_peripheral_access(&self, _: &C, _: &Self::RegisterType)
Called after peripheral access.
Currently used primarily for power management to check whether the peripheral can be powered off.
