Hello kernelnewbies list, I've run into situations where it would be practical to have the GPIO, I2C and SPI functionality some FTDI chips provide as kernel devices. (The chips are more often used as USB serial adapters; only that feature is supported by the current kernel drivers). The presence of an extensive userspace library (libftdi) and the observation of a project in a similar situation[1] that has not made it into the kernel makes me doubt that implementing that in the kernel is the way to go. I've written up more thoughts on this on [2], including exploration of userspace SPI/GPIO/I2C devices (think FUSE / USBIP / uinput), but it boils down to a simple question: Is support for alternative operation modes in FTDI chips something that is welcome and (easily) feasible in the kernel? Best regards chrysn [1] http://danielthesantos.blogspot.co.at/2013/08/why-mcp2210-driver.html [2] http://christian.amsuess.com/idea-incubator/ftdi-kernel-support/ -- You don't become great by trying to be great.
