a=ed25519; pk=j25LRSikYRlv0PpovZSgSrCQwsy7WDzIYum/mydUa3A= The delay_on, delay_off and invert attributes are created by several LED triggers, but only the oneshot variants are documented. Adding a separate ABI file per trigger would make get_abi.py report the same sysfs path as defined more than once, so patch 2 moves these entries to sysfs-class-led and describes each trigger's behaviour there. Patch 1 is a small preparatory fix: the existing inverted entry still mentions the gpio trigger, which no longer creates that attribute. Checked with tools/docs/get_abi.py validate (no new warnings) and scripts/checkpatch.pl (clean). Signed-off-by: Wayne Ho --- Changes in v2: - Capitalize the description after the subject prefix, and reword patch 1's subject to start with a verb (Sashiko) - Add Fixes tag to patch 1 and reference the commit that removed the attribute (Griffin) - Link to v1: https://patch.msgid.link/20261001-docs-leds-abi-trigger-attrs-v1-0-54f0529bf0f6@gmail.com --- Wayne Ho (2): Documentation: ABI: leds: Drop stale gpio trigger reference for inverted Documentation: ABI: leds: Document timer, heartbeat and activity attributes Documentation/ABI/testing/sysfs-class-led | 73 +++++++++++++++++++++- .../ABI/testing/sysfs-class-led-trigger-oneshot | 29 --------- 2 files changed, 70 insertions(+), 32 deletions(-) --- base-commit: 5dd1818b15d98d4a20806cd00b1b40320b06004f change-id: 20261001-docs-leds-abi-trigger-attrs-a20ed96981dd Best regards, -- Wayne Ho
