2020-02-11spi: add driver for ar934x spi controllerChuanhong Guo
This patch adds driver for SPI controller found in Qualcomm Atheros AR934x/QCA95xx SoCs. 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.
