Subject: [PATCH] leds: mlxreg: Add support for new flavour of capability
|
|
register
|
|
X-NVConfidentiality: public
|
|
|
|
LED platform data is common across the various systems, while LED
|
|
driver should be able to apply only the LED instances relevant
|
|
to specific system.
|
|
|
|
For example, platform data might contain descriptions for fan1,
|
|
fan2, ..., fan{n} LEDs, while some systems equipped with all 'n' fan
|
|
LEDs, others with less.
|
|
|
|
For detection of the real number of equipped LEDs special capability
|
|
register is used.
|
|
This register used to indicate presence of LED through the bitmap.
|
|
|
|
For some new big modular systems this register will provide presence
|
|
data by counter.
|
|
|
|
Use slot parameter to distinct whether capability register contains
|
|
bitmask or counter.
