tools: gpio: remove uAPI v1 code no longer used by selftests

2021-02-15T10:43:28+00:00

gpio-mockup-chardev helper has been obsoleted and removed, so also remove
the tools/gpio code that it, and nothing else, was using.

tools: gpio: fix %llu warning in gpio-watch.c

2021-01-18T09:05:35+00:00

Some platforms, such as mips64, don't map __u64 to long long unsigned
int so using %llu produces a warning:

gpio-watch.c: In function ‘main’:
gpio-watch.c:89:30: warning: format ‘%llu’ expects argument of type ‘long long unsigned int’, but argument 4 has type ‘__u64’ {aka ‘long unsigned int’} [-Wformat=]

Replace the %llu with PRIu64 and cast the argument to uint64_t.

tools: gpio: add multi-line monitoring to gpio-event-mon

2020-09-30T08:57:27+00:00

Extend gpio-event-mon to support monitoring multiple lines.
This would require multiple lineevent requests to implement using uAPI v1,
but can be performed with a single line request using uAPI v2.
