    Subject[PATCH v6 2/2] platform/mellanox/mlxbf-bootctl: Add the ABI definitions
    Date
    This commit adds the ABI definitions exposed to userspace for
    the platform/mellanox/mlxbf-bootctl driver.

    Reviewed-by: Vadim Pasternak <vadimp@mellanox.com>

    v5->v6:
    Fixes for comments from Mark:
    - Changed to use device attributes (DEVICE_ATTR_xx) instead of
    driver attributes (DRIVER_ATTR_xx) for the exported sysfs
    attributes.
