menuconfig I2C_SAM0
	bool "SAM0 series I2C SERCOM driver"
	default y
	depends on DT_HAS_ATMEL_SAM0_I2C_ENABLED
	select PINCTRL
	help
	  Enable the SAM0 series SERCOM I2C driver.

config I2C_SAM0_DMA_DRIVEN
	bool "DMA support for SAM0 I2C devices"
	depends on I2C_SAM0
	select DMA
	help
	  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.

config I2C_SAM0_TRANSFER_TIMEOUT
	int "Transfer timeout [ms]"
	default 500
	help
	  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.
