docs: ABI: sysfs-class-led-trigger-pattern: remove hw_pattern duplication
The ABI files are supposed to be unique. Yet, in the specific case of hw_pattern, there are some duplicated entries as warned by scripts/get_abi.pl: Warning: /sys/class/leds/<led>/hw_pattern is defined 3 times: Documentation/ABI/testing/sysfs-class-led-trigger-pattern:14 Documentation/ABI/testing/sysfs-class-led-driver-sc27xx:0 Documentation/ABI/testing/sysfs-class-led-driver-el15203000:0 Drop the duplication from the ABI files, moving the specific definitions to files inside Documentation/leds.

Description:

Specify a hardware pattern for the SC27XX LED. For the SC27XX

LED controller, it only supports 4 stages to make a single

hardware pattern, which is used to configure the rise time,

high time, fall time and low time for the breathing mode.
|
||||
|
||||
For the breathing mode, the SC27XX LED only expects one brightness
|

for the high stage. To be compatible with the hardware pattern
|
||||
format, we should set brightness as 0 for rise stage, fall
|

stage and low stage.
|
||||
|
||||
- Min stage duration: 125 ms
|

- Max stage duration: 31875 ms
|

|
||||
Since the stage duration step is 125 ms, the duration should be
|
||||
a multiplier of 125, like 125ms, 250ms, 375ms, 500ms ... 31875ms.
|
||||
|

Thus the format of the hardware pattern values should be:

"0 rise_duration brightness high_duration 0 fall_duration 0 low_duration".
