47284e3e0f spi: sun4i: allow transfers to set transmission speed 
Allow transfers to set the transmission speed rather than using the
device max_speed_hz value. The SPI core makes sure that the speed_hz
value is always set on the transfer.

14ac00e033 spi: drop owner assignment from platform_drivers 
A platform_driver does not need to set an owner, it will be populated by the
driver core.

743a46b89a spi: sun6i: Set bits_per_word_mask to only support 8 bits word length 
This controller only supports 8 bits word length.
Set bits_per_word_mask so spi core will reject transfers that attempt to use
an unsupported bits_per_word value.

d31ad46f58 spi: sun6i: Fix define for SUN6I_TFR_CTL_CS_MASK 
Current code in sun6i_spi_set_cs() actually clears CPHA and CPOL bits which is
obvious wrong. The define for SUN6I_TFR_CTL_CS_MASK is wrong. Fix it.

3558fe900e spi: sunxi: Add Allwinner A31 SPI controller driver 
The Allwinner A31 has a new SPI controller IP compared to the older Allwinner
SoCs.

It supports DMA, but the driver only does PIO for now, and DMA will be
supported eventually.
