(e.g. for Renesas MTU3 hardware used for phase counting). Signed-off-by: Biju Das Reviewed-by: William Breathitt Gray --- v13->v14: * No change. v12->v13: * Updated kernel version from 6.3->6.4 as it is too late. v11->v12: * No change v10->v11: * No change. v9->v10: * Added Rb tag from William Breathitt Gray v8->v9: * Added available blocks for external_input_phase_clock_select_available * Removed the "This attribute" from the external_input_phase_clock_select description, and capitalize the word "counter" from description. * Removed the "This attribute" from the cascade_counts_enable description, and capitalize "counts" and "counter" * Moved these device-level configuration blocks to top of the file. 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 | 32 +++++++++++++++++++++ 1 file changed, 32 insertions(+) diff --git a/Documentation/ABI/testing/sysfs-bus-counter b/Documentation/ABI/testing/sysfs-bus-counter index ff83320b4255..1417c4272c6c 100644 --- a/Documentation/ABI/testing/sysfs-bus-counter +++ b/Documentation/ABI/testing/sysfs-bus-counter @@ -1,3 +1,33 @@ +What: /sys/bus/counter/devices/counterX/cascade_counts_enable +KernelVersion: 6.4 +Contact: linux-iio@vger.kernel.org +Description: + Indicates the cascading of Counts on Counter X. + + Valid attribute values are boolean. + +What: /sys/bus/counter/devices/counterX/external_input_phase_clock_select +KernelVersion: 6.4 +Contact: linux-iio@vger.kernel.org +Description: + 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 +KernelVersion: 6.4 +Contact: linux-iio@vger.kernel.org +Description: + Discrete set of available values for the respective device + configuration are listed in this file. + What: /sys/bus/counter/devices/counterX/countY/count KernelVersion: 5.2 Contact: linux-iio@vger.kernel.org @@ -215,6 +245,8 @@ 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_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
