From: Johan Hovold Date: Mon, 13 Jul 2020 10:55:15 +0000 (+0200) Subject: USB: serial: cp210x: add support for TIOCGICOUNT X-Git-Tag: v5.10.7~1952^2~29^2~5 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=de9c7e9f278492cee9f217ffc339a398536c7e51;p=platform%2Fkernel%2Flinux-rpi.git USB: serial: cp210x: add support for TIOCGICOUNT Enable TIOCGICOUNT to allow reading out the (unused) interrupt counters and error statistics. Note that modem-status events are currently left unimplemented as they appear to be buffered on at least CP2102 and therefore cannot be used to implement TIOCMIWAIT.
