Adds support for configuring the omap2-mcspi driver use autosuspend for
runtime power management. This can reduce the latency in starting an
spi transfer by not suspending the device immediately following
completion of a transfer. If another transfer then takes place before
the autosuspend timeout
The various devm_* functions allocate memory that is released when a driver
detaches. This patch uses devm_request_and_ioremap
to request memory in probe function. Since the freeing is not
needed the calls are deleted from remove function.Also use
use devm_kzalloc for the cs memory allocation.
From: Felipe Balbi ba...@ti.com
move probe away from __init section and use
platform_driver_register() instead of
platform_driver_probe().

bus_num was used to reference the mcspi controller instance in a fixed array.
Remove this array and store this information directly inside drvdata structure.
bus_num is now just set if the pdev-id is present or with -1 for dynamic
allocation by SPI core, but
Structure struct spi_imx_data is defined twice.
Remove one of its definition.

Structure struct spi_imx_data is defined twice.
Remove one of its definition.
In order to do so, it is also necessary to move spi_imx_devtype_data
structure after the definition of spi_imx_data.

In my version of drivers/spi/spi-imx.c struct spi_imx_data is only
defined once. I guess you wanted to say forward declaration.
Yes, correct.
...
Does this really work? struct spi_imx_data has a member
Yes, tested it on a mx31pdk board.
