This series adds drivers and FPGA manager support required for FT232H based ARRI FPGA configuration adapters. Patch 1/3 adds FT232H interface driver (for ARRI USB PIDs) implementing commonly used FTDI USB transfer operations and ACBUS/MPSSE GPIO controllers. Depending on USB PIDs it creates platform devices for MPSSE SPI bus with attached SPI slaves or platform devices for ARRI FPP FPGA manager. Patch 2/3 adds MPSSE SPI controller driver which registers an FTDI USB-SPI bus with attached SPI slaves from description in platform data, so existing SPI protocol drivers can be used for these slave devices (in our case altera-ps-spi). Via interface driver in patch 1/3 it is easily possible to add support for other slave devices using custom USB PIDs (e.g. spi-nor flash W25Q32 with m25p80 driver has beed used for testing MPSSE SPI controller driver). Patch 3/3 adds FPGA manager driver for ARRI FPP adapters for FPGA configuration via Altera fast passive parallel interface.
