Struct Item 

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

The common fields shared by all linked-list item types (TR1, TR2, BR1, SAR, DAR).

This is the first 5 words of every GPDMA linked-list descriptor. Both LinearItem and TwoDItem embed this as their first field so the #[repr(C)] hardware layout is preserved.

Fields

tr1: ChTr1

Transfer register 1.

tr2: ChTr2

Transfer register 2.

br1: ChBr1

Block register 1.

sar: u32

Source address register.

dar: u32

Destination address register.
