spi: add driver for J-Core SPI controller 2016-08-08T10:56:32+00:00 Rich Felker dalias@libc.org 2016-08-04T04:30:37+00:00 2cb1b3b3ac0ac86b70eb1ecd65585c0d024fe273 The J-Core "spi2" device is a PIO-based SPI master controller. It differs from "bitbang" devices in that that it's clocked in hardware rather than via soft clock modulation over gpio, and performs byte-at-a-time transfers between the cpu and SPI controller. This driver will be extended to support future versions of the J-Core SPI controller with DMA transfers when they become available.
