Dear all,
DENX Software Engineering develops and brings this driver to mainline on
behalf of us (ARRI*).
Since there was a lot of discussion around this patch series I would
highly appreciate if someone could sum up what needs to be changed in
detail in order to get this driver into the mainline as I am used it
from the other "line-by-line" reviews. I understood that the approach is
not generic enough - please correct me if I am wrong on that point. We
somehow need a commitment that if we change it to another way that the
whole discussion does not start from scratch.
Many thanks
Eric

This series adds support for fast passive parallel (FPP) Altera
FPGA configuration using FTDI FT232H chip in FT245-FIFO mode.
It has been used to configure Arria 10 FPGAs.
Patch 1 adds an FT232H MFD driver with common functions that
can be used for FT232H USB-GPIO/I2C/SPI master adapter drivers.
Currently it is used for FT232H GPIO support (in patch 2) and
for FT245 FIFO transfers in FPP FPGA manager driver in patch 3.
Driver support for FT232H USB-I2C/SPI master adapters can be
added later.
Patch 2 adds a simple GPIO driver supporting four FT232H CBUS GPIOs.
Patch 3 adds an FPGA Manager driver for Altera FPP FPGA configuration
via FT232H FT245-FIFO interface.
