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