7 (see Documentation/spi/spi-summary.rst). The driver has the following features
9 - Support for any PXA2xx and compatible SSP.
10 - SSP PIO and SSP DMA data transfers.
11 - External and Internal (SSPFRM) chip selects.
12 - Per slave device (chip) configuration.
13 - Full suspend, freeze, resume support.

109 FIFO overruns (especially in PIO mode transfers). Good default values are::
119 to determine the correct value. An SSP configured for byte-wide transfers would
127 timeouts and must busy-wait any trailing bytes.

184 DMA and PIO I/O Support
185 -----------------------
186 The pxa2xx_spi driver supports both DMA and interrupt driven PIO message
187 transfers.  The driver defaults to PIO mode and DMA transfers must be enabled
190 it automatically and try it first with a possible fallback to PIO. The DMA
197 	always use PIO transfers
201 	use PIO transfers
210 	use PIO transfer
