10104 + * there's a native SPI+IRQ+DMA controller driver ... such a driver should
10105 + * be a drop-in replacement for this one, and much faster.
10106 + *
10107 + * remember:
10108 + *
10109 + * - other at91 parts (like at91sam9) have multiple controllers
10110 + * and different pin muxing; this version is at91rm9200 specfic.
10111 + *
10112 + * - at91sam9261 SPI0 pins are directly muxed with MMC/SD pins.
10113 + *
10114 + * - rm9200 spi chipselects drop wrongly, so the native driver
10115 + * will need to use gpios much like this does.
10116 + *
10117 + * - real hardware only allows 8..16 bits per word, while this
10118 + * bitbanger allows 1..32 (incompatible superset).
10119 + *
10120 + * - this disregards clock parameters. with inlined gpio calls,
10121 + * gcc 3.4.4 produces about 1.5 mbit/sec, more than 2x faster
10122 + * than using the subroutined veresion from txrx_word().
10123 + *
10124 + * - suspend/resume and <linux/clk.h> support is missing ...

12890 + * operating states which sacrifice functionality for lower power usage.
12891 + *
12892 + * The constraint value is commonly tested in device driver suspend(), to
12893 + * leave clocks active if they are needed for features like wakeup events.
12894 + * On platforms that support reduced functionality operating states, the
