This enables DMA driven transactions for the I2C peripheral.
|
|
|
|
|
DMA driven mode requires fewer interrupts to handle the
|
|
|
|
|
transaction and ensures that high speed modes are not delayed
|
|
|
|
|
by data reloading.

Timeout in milliseconds used for each I2C transfer.

0 means that the driver should use the K_FOREVER value,
|
|
|
|
|
i.e. it should wait as long as necessary.
