15 * The i.MX SSI core has some nasty limitations in AC97 mode. While most
16 * sane processor vendors have a FIFO per AC97 slot, the i.MX has only
17 * one FIFO which combines all valid receive slots. We cannot even select
18 * which slots we want to receive. The WM9712 with which this driver
19 * was developped with always sends GPIO status data in slot 12 which
20 * we receive in our (PCM-) data stream. The only chance we have is to
21 * manually skip this data in the FIQ handler. With sampling rates different
22 * from 48000Hz not every frame has valid receive data, so the ratio
23 * between pcm data and GPIO status data changes. Our FIQ handler is not
24 * able to handle this, hence this driver only works with 48000Hz sampling
25 * rate.
26 * Reading and writing AC97 registers is another challange. The core
27 * provides us status bits when the read register is updated with *another*
28 * value. When we read the same register two times (and the register still
29 * contains the same value) these status bits are not set. We work
30 * around this by not polling these bits but only wait a fixed delay.
