description: |
|
|
This spi controller support single, dual, or quad mode transfer for
|
|
SPI NOR flash. There should be only one spi slave device following
|
|
generic spi bindings. It's not recommended to use this controller
|
|
for devices other than SPI NOR flash due to limited transfer
|
|
capability of this controller.
