Subject[PATCH 0/2] spi: add driver for ar934x spi controller
Date
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.
