Hi Mark, This series adds support for SPI on Cavium's ThunderX (arm64). The SPI hardware is the same as on MIPS Octeon, the only difference is that the device appears as a PCI device. To avoid copy and paste of the Octeon driver I've moved the common parts into a shared file.
Patches #1-5 prepare the Octeon driver for re-use. Patch #6 adds the ThunderX driver. The series was tested on MIPS (Edge Router PRO and cn71xx) and ThunderX. Feedback welcome! thanks, Jan Jan Glauber (5): spi: octeon: Store system clock freqency in struct octeon_spi spi: octeon: Put register offsets into a struct spi: octeon: Move include file from arch/mips to drivers/spi spi: octeon: Split driver into Octeon specific and common parts spi: octeon: Add thunderx driver Steven J.
