(e.g. for Renesas MTU3 hardware used for phase counting). Signed-off-by: Biju Das --- v7->v8: * Replaced cascade_enable->cascade_counts_enable * Updated commit header and description * Added external_input_phase_clock_select_available entry for driver- specific enum attribute and created a new entry block for it. * Add a line stating cascade_counts_enable is a boolean attribute. * Added missing 'component_id' suffix. v6->v7: * Replaced long_word_access_ctrl_mode->cascade_enable * Updated Kernel version v5->v6: * No change v5: * New patch --- Documentation/ABI/testing/sysfs-bus-counter | 25 +++++++++++++++++++++ 1 file changed, 25 insertions(+) diff --git a/Documentation/ABI/testing/sysfs-bus-counter b/Documentation/ABI/testing/sysfs-bus-counter index ff83320b4255..2e7a25010c84 100644 --- a/Documentation/ABI/testing/sysfs-bus-counter +++ b/Documentation/ABI/testing/sysfs-bus-counter @@ -60,6 +60,20 @@ Description: counter does not freeze at the boundary points, but counts continuously throughout. +What: /sys/bus/counter/devices/counterX/external_input_phase_clock_select +KernelVersion: 6.3 +Contact: linux-iio@vger.kernel.org +Description: + This attribute selects the external clock pin for phase + counting mode of counter X. + + MTCLKA-MTCLKB: + MTCLKA and MTCLKB pins are selected for the external phase clock. + + MTCLKC-MTCLKD: + MTCLKC and MTCLKD pins are selected for the external phase clock. + +What: /sys/bus/counter/devices/counterX/external_input_phase_clock_select_available What: /sys/bus/counter/devices/counterX/countY/count_mode_available What: /sys/bus/counter/devices/counterX/countY/error_noise_available What: /sys/bus/counter/devices/counterX/countY/function_available @@ -215,6 +229,17 @@ Contact: linux-iio@vger.kernel.org Description: This attribute indicates the number of overflows of count Y. +What: /sys/bus/counter/devices/counterX/cascade_counts_enable +KernelVersion: 6.3 +Contact: linux-iio@vger.kernel.org +Description: + This attribute indicates the cascading of counts on + counter X. + + Valid attribute values are boolean. + +What: /sys/bus/counter/devices/counterX/cascade_counts_enable_component_id +What: /sys/bus/counter/devices/counterX/external_input_phase_clock_select_component_id What: /sys/bus/counter/devices/counterX/countY/capture_component_id What: /sys/bus/counter/devices/counterX/countY/ceiling_component_id What: /sys/bus/counter/devices/counterX/countY/floor_component_id
