Kuninori Morimoto bb9c5687e8 spi: sh-hspi: modify write/read method
Current sh-hspi had wrong write/read method which was not linux standard.
If spi_transfer requests tx[2], rx[2] len=2,
then, driver should run tx[0], rx[0], tx[1], rx[1].
But current sh-hspi runs tx[0], tx[1], rx[0], rx[1].
This patch fixes it up.

Kuninori Morimoto 49e599b859 spi: sh-hspi: control spi clock more correctly
Current sh-hspi had used platform-specific speed.
This patch remove it, and use spi_transfer specific speed.
It removes unnecessary flags from struct sh_hspi_info,
but struct sh_hspi_info is still exist, since sh-hspi needs
platform info in the future.

Kuninori Morimoto d1c8bbd793 spi: Add SuperH HSPI prototype driver
This patch adds SuperH HSPI driver.
It is still prototype driver, but has enough function at this point.
