### Changed
- DMA channel objects now implement `Peripheral` (#2526)
- In addition to taking by value, peripheral drivers can now mutably borrow DMA channel objects. (#2526)
- DMA channel objects are no longer wrapped in `Channel`. The `Channel` drivers are now managed by DMA enabled peripheral drivers. (#2526)
- The `Dpi` driver and `DpiTransfer` now have a `Mode` type parameter. The driver's asyncness is determined by the asyncness of the `Lcd` used to create it. (#2526)
- `dma::{Channel, ChannelRx, ChannelTx}::set_priority` for GDMA devices (#2403)

## DMA changes
### Accessing channel objects
DMA channels are now available through the `Peripherals` struct, which is returned
by `esp_hal::init()`. The channels themselves have been renamed to match other peripheral singletons.
- ESP32-C2, C3, C6, H2 and S3: `channelX -> DMA_CHX`
- ESP32 and S2: `spiXchannel -> DMA_SPIX`, `i2sXchannel -> DMA_I2SX`
```diff
-let dma = Dma::new(peripherals.DMA);
-let channel = dma.channel2;
+let channel = peripherals.DMA_CH2;
```
### Configuration changes
- `configure_for_async` and `configure` have been removed
