- config MXC_SAHARA_POLL_MODE
- bool "Force driver to POLL for hardware completion."
- depends on MXC_SAHARA
- default n
- ---help---
- When this flag is yes, the driver will not use interrupts to
- determine when the hardware has completed a task, but instead
- will hold onto the CPU and continually poll the hardware until
- it completes.

- depends on MXC_SAHARA_POLL_MODE

- will exit after the given number of iterations.
