Struct LinearItem

#[repr(C)]
pub struct LinearItem {
    pub tr1: ChTr1,
    pub tr2: ChTr2,
    pub br1: ChBr1,
    pub sar: u32,
    pub dar: u32,
    pub llr: ChLlr,
}

A linked-list item for linear GPDMA transfers.

Also works for 2D-capable GPDMA channels, but does not use 2D capabilities.

Fields

tr1: ChTr1

Transfer register 1.

tr2: ChTr2

Transfer register 2.

br1: ChBr1

Block register 2.

sar: u32

Source address register.

dar: u32

Destination address register.

llr: ChLlr

Linked-list address register.
