Hmm...
$ git grep /sys/bus/iio/devices/iio:deviceX/in_count_quadrature_mode_available
Documentation/ABI/testing/sysfs-bus-iio-counter-104-quad-8:What: /sys/bus/iio/devices/iio:deviceX/in_count_quadrature_mode_available
Documentation/ABI/testing/sysfs-bus-iio-lptimer-stm32:What: /sys/bus/iio/devices/iio:deviceX/in_count_quadrature_mode_available
Documentation/ABI/testing/sysfs-bus-iio-timer-stm32:What: /sys/bus/iio/devices/iio:deviceX/in_count_quadrature_mode_available
Even re-doing the changes from
changeset b299d00420e2 ("IIO: stm32: Remove quadrature related functions from trigger driver")
at Documentation/ABI/testing/sysfs-bus-iio-timer-stm32, there's still
a third duplicate of some of those, as reported by the script:
$ ./scripts/get_abi.pl validate 2>&1|grep quadra
Warning: /sys/bus/iio/devices/iio:deviceX/in_count0_quadrature_mode is defined 2 times: Documentation/ABI/testing/sysfs-bus-iio-timer-stm32:117 Documentation/ABI/testing/sysfs-bus-iio-lptimer-stm32:14
Warning: /sys/bus/iio/devices/iio:deviceX/in_count_quadrature_mode_available is defined 3 times: Documentation/ABI/testing/sysfs-bus-iio-counter-104-quad-8:2 Documentation/ABI/testing/sysfs-bus-iio-timer-stm32:111 Documentation/ABI/testing/sysfs-bus-iio-lptimer-stm32:8
As in_count_quadrature_mode_available is also defined at:
Documentation/ABI/testing/sysfs-bus-iio-counter-104-quad-8:2
The best here seems to have a patch that will also drop the other
duplication of this, probably moving in_count_quadrature_mode_available
to a generic node probably placing it inside
Documentation/ABI/testing/sysfs-bus-iio.
Comments?
Thanks,
Mauro
PS.: the IIO subsystem is the one that currently has more duplicated
ABI entries:
