[PATCH] SPI: Freescale iMX SPI controller driver (BIS+)
Add the SPI controller driver for Freescale i.MX(S/L/1). Main features summary: > Per chip setup via board specific code and/or protocol driver. > Per transfer setup. > PIO transfers. > DMA transfers. > Managing of NULL tx / rx buffer for rd only / wr only transfers. This patch replace patch-2.6.20-rc4-spi_imx with the following changes: > Few cosmetic changes. > Function map_dma_buffers now return 0 for success and -1 for failure. > Solved a bug inside spi_imx_probe function (wrong error path). > Solved a bug inside setup function (bad undo setup for max_speed_hz). > For read-only transfers, always write zero bytes. This is almost the same as the 'BIS' version sent by Andrea, except for updating the 'DUMMY' byte so that read-only transfers shift out zeroes. That part of the API changed recently, since some half duplex peripheral chips require that semantic.
