* mpc52xx_lpbfifo_sclpc_irq - IRQ handler for LPB FIFO

- * On transmit, the dma completion irq triggers before the fifo
- * completion triggers. Handle the dma completion here instead of the
- * LPB FIFO Bestcomm task completion irq because everything is not
- * really done until the LPB FIFO completion irq triggers.
- *
- * In other words:
- * For DMA, on receive, the "Fat Lady" is the bestcom completion irq. on
- * transmit, the fifo completion irq is the "Fat Lady". The opera (or in
- * this case the DMA/FIFO operation) is not finished until the "Fat
- * Lady" sings.
- *
* Reasons for entering this routine:
* 1) PIO mode rx and tx completion irq
* 2) DMA interrupt mode tx completion irq
