This controller is a superset of the already supported qca,ar7100-spi. Besides the bit-bang mode in spi-ath79.c, this new controller added a new "shift register" mode, allowing faster spi operations. This mode doesn't need all the bit-bang code in spi-ath79.c and needs a different clock setup, so I decided to write a new driver for it instead of extending current spi-ath79 driver.
