Subject: [PATCH 04/69] spi: qup: Fix transaction done signaling
|
|
|
|
Wait to signal done until we get all of the interrupts we are expecting
|
|
to get for a transaction. If we don't wait for the input done flag, we
|
|
can be inbetween transactions when the done flag comes in and this can
|
|
mess up the next transaction.
