Any advice on how to figure out where it is locking up? This command works fine to connect two x86 laptops. At 1200 it does take a while for an xterm to show up, though. Try it without the crtscts (actually, use nocrtscts instead of crtscts). That will tell us whether it is hardware flow control causing problems. IIRC, those mac serial ports didn't have all of RTS, CTS, CD and DTR, but I don't recall which one(s) were missing. Also make sure you don't have the xonxoff option. iirc, RTS is missing and on MacOS we typically have an option to use DTR instead. There's also some issues with CTS polarity which is different between the actual serial ports, vs. some internal modems or something around those lines.

[PATCH 2/2] usb/fsl_qe_udc: Check for muram allocation errors
The QE UDC doesn't check for cpm_muram_alloc() return values, this
might cause all sorts of misbehaviour when cpm_muram_alloc() failed
to allocate the muram memory.
While at at, change few dev_dbg() calls to dev_err(), so that the
driver would not die silently.

[PATCH] powerpc/qe: Select QE_USB with USB_GADGET_FSL_QE
Boards should know when QE_USB is used, so that they can configure USB clocks and pins. Another option would be to add 'select QE_USB' into USB_GADGET_FSL_QE, but selects are evil since they don't support dependencies. While at it, also remove 'host' from the symbol description, since the QE_USB code is used to support the gadget driver as well.

[PATCH] usb/fsl_qe_udc: Implement port reset
Without that patch a USB host won't find the QE UDC device if a USB
cable plugged before the QE UDC probe. A user have to re-plug the
USB cable so that the host would reenumerate the device.
To solve the issues the QE UDC should reset the port at bind time.

I know you don't like it, but I ask you to reconsider it. The I2C and SPI cases are similar, and recently we tried to write bindings for some I2C GPIO controllers. This new version is a bit better in that you've generalised thing more. I'd still prefer if we can have an interface where the driver doesn't have to know that it is on an ACPI/OF/EFI/whatnot host, but I can live with this model for now.
