here we could conceivable do something else useful while waiting
on the spi controller.
But if there's number to prove otherwise..

It's atleast in line with what we do elsewhere (spi-gpio, i2c-gpio,
i2c-mux-gpio, ..)

DI
From: Dries Van Puymbroeck
This patch contains a driver for a gpio controlled multiplexer on an
SPI bus. This can be useful if a board requires more SPI devices,
and thus more chip selects, than the SPI controller on the processor
has available.
The mux device is added in the device tree as a ch

Rather than the deprecated spi_s3c24xx_gpio driver.
Only compile tested. Notice that the board support seems quite broken
as the spi_s3c24xx_gpio platform device name was misspelled and there
is no struct spi_board_info defined, but this atleast didn't make it
any worse.

It was equivalent to spi-gpio, and there's no longer any in-tree users
of it, so get rid of it.

(at 66MHz / 32bits we're talking over 2 million interrupts per
second - E.G. only ~100 instructions between each!)
Maybe it indeed makes more sense to use polling for high bitrates.

Make spi_mpc83xx more robust against odd transfer sizes:
- Error out on transfer length != multiple of bytes per word
- Fix crash on transfer length = 0 (1 word was always sent and

Commit a61f5345 (spi_mpc83xx clockrate fixes) broke clockrate
calculation for low speeds. SPMODE_DIV16 should be set if the
divider is higher than 64, not only if the divider gets clipped
to 1024.
Furthermore, the clipping check was off by a factor 16 as well.
