This adds the vid:pid of the isodebug v1 isolated JTAG/SWD+UART. Only the
second channel is available for use as a serial port.

docs: usb: rename files to .rst and add them to drivers-api

2019-06-20T12:28:36+00:00

While there are a mix of things here, most of the stuff
were written from Kernel developer's PoV. So, add them to
the driver-api book.

A follow up for this patch would be to move documents from
there that are specific to sysadmins, adding them to the
admin-guide.

USB: serial: f81232: clear overrun flag

2019-05-03T07:19:54+00:00

The F81232 will report data and LSR with bulk like following format:
bulk-in data: [LSR(1Byte)+DATA(1Byte)][LSR(1Byte)+DATA(1Byte)]...

LSR will auto clear frame/parity/break error flag when reading by H/W,
but overrrun will only cleared when reading LSR. So this patch add a
worker to read LSR when overrun and flush the worker on close() &
suspend().
