[v3,04/10] platform_data/mlxreg: Add capability bit and mask fields

Commit Message

Vadim Pasternak Jan. 16, 2025, 7:59 a.m. UTC

Some 'capability' registers can be shared between different resources.
Add new fields 'capability_bit' and 'capability_mask' to structs
'mlxreg_core_data' and 'mlxreg_core_item' for getting only relevant
capability bits.
