This is a patch series for SPI driver for Sunplus SP7021 SoC.

Sunplus SP7021 is an ARM Cortex A7 (4 cores) based SoC. It integrates
many peripherals (ex: UART, I2C, SPI, SDIO, eMMC, USB, SD card and
etc.) into a single chip. It is designed for industrial control.

The structure of the driver now looks good, but there are some smaller
issues remaining - I don't think I saw anything that Andy and Lukas
didn't already raise.
