Support monitoring and detecting the SD-FEC error events through IRQ and poll file operation. The SD-FEC device can detect one-error or multi-error events. An error triggers an interrupt which creates and run the ONE_SHOT IRQ thread. The ONE_SHOT IRQ thread detects type of error and pass that information to the poll function. The file_operation callback poll(), collects the events and updates the statistics accordingly. The function poll blocks() on waiting queue which can be unblocked by ONE_SHOT IRQ handling thread. Support SD-FEC interrupt set ioctl callback. The SD-FEC can detect two type of errors: coding errors (ECC) and a data interface errors (TLAST). The errors are events which can trigger an IRQ if enabled. The driver can monitor and detect these errors through IRQ. Also the driver updates the statistical data.
