+Subject: [PATCH backport 6.1.42 42/85] hwmon: (mlxreg-fan) Add support for new
+ flavour of capability register
+
+FAN platform data is common across the various systems, while fan
+driver should be able to apply only the fan instances relevant
+to specific system.
+
+For example, platform data might contain descriptions for fan1,
+fan2, ..., fan{n}, while some systems equipped with all 'n' fans,
+others with less.
+Also, on some systems fan drawer can be equipped with several
+tachometers and on others only with one.
+
+For detection of the real number of equipped drawers and tachometers
+special capability registers are used.
+These registers used to indicate presence of drawers and tachometers
+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.
