Subject: gpio-hog names
Date: Sun, 06 Sep 2026 19:05:09 +0000 [thread overview]
Message-ID: <55267dce42a63e5210c34e49747f564f5cc0b0cf@linux.dev> (raw)
Hi,
Until v7.0, GPIO hogs inherited the DT node name when no line-name
property was specified. This was implemented as a fallback in
of_parse_own_gpio().
Commit d1d564ec4992 ("gpio: move hogs into GPIO core") moved hog parsing
into the GPIO core and removed this fallback.
Consequently, GPIO hogs without a line-name property are now displayed
with a ? in /sys/kernel/debug/gpio.
Is this an intentional change, or should the fallback to the DT node name
be retained?
regards Frank
