Cover letter [PATCH RESEND 00/12] USB: serial: xr: add support for more device types
[ I apparently missed the last three patches of the series when posting
on March 30th so resending the whole series. ]
This series adds support for another nine models of Maxlinerar/Exar USB UARTs to the xr driver. The various models can be divided into four types:
XR21V141X
XR21B142X
XR21B1411
XR22804with different register layouts and features.
All types can be used in CDC-ACM mode but further features such as hardware and software flow control and in-band line status are available in a second "custom driver" mode.
The fact that hardware flow control is enabled by default in CDC-ACM mode also prevents using the standard CDC-ACM driver in cases where the hardware engineers have failed to properly connect the CTS input.
The currently supported XR21V141X type stands out from the other three by not being able to accept CDC requests without always entering CDC-ACM mode, requiring a different enable/disable sequence and by using a distinct register layout for certain functionality.
Expect for the above, most differences can be handled by simply using different set of register addresses.
Note that this series depends on the recently posted multi-interface-function series.
