source · pub struct Smhc {
isr: &'static IsrData,
smhc: &'static RegisterBlock,
int: (Interrupt, fn()),
num: u8,
}
Fields§
§isr: &'static IsrData
§smhc: &'static RegisterBlock
§int: (Interrupt, fn())
§num: u8
Implementations§
source§impl Smhc
impl Smhc
sourcepub unsafe fn smhc0(smhc: SMHC0, ccu: &mut Ccu, gpio: &mut GPIO) -> Self
pub unsafe fn smhc0(smhc: SMHC0, ccu: &mut Ccu, gpio: &mut GPIO) -> Self
Initialize SMHC0 for SD cards.
§Safety
- The
SMHC0
register block must not be concurrently written to. - This function should be called only while running on an Allwinner D1.
sourceunsafe fn init(
smhc: &'static RegisterBlock,
int: Interrupt,
isr: fn(),
num: u8,
) -> Self
unsafe fn init( smhc: &'static RegisterBlock, int: Interrupt, isr: fn(), num: u8, ) -> Self
This assumes the GPIO pin mappings and module clock are already configured.
fn reset_fifo(regs: &RegisterBlock)
sourceunsafe fn prepare_dma(&self, descriptor: &Descriptor, byte_cnt: u32)
unsafe fn prepare_dma(&self, descriptor: &Descriptor, byte_cnt: u32)
§Safety
The descriptor chain needs to live at least as long as the DMA transfer. Additionally, their content (e.g., the validity of the buffers they point to) also needs to be verified by the user.
sourcepub fn handle_smhc0_interrupt()
pub fn handle_smhc0_interrupt()
Handle an interrupt for SMHC0
pub async fn register( self, kernel: &'static Kernel, queued: usize, ) -> Result<(), RegistrationError>
async fn run(self, rx: RequestStream<SdmmcService>)
async fn command(&self, params: Command) -> Result<Response, Error>
