NAME

       ata_finalize_port_ops - finalize ata_port_operations

SYNOPSIS

       void ata_finalize_port_ops(struct ata_port_operations * ops);

ARGUMENTS

       ops
	   ata_port_operations to finalize

DESCRIPTION

       An ata_port_operations can inherit from another ops and that ops can again inherit from another. This can go on as many times as necessary
       as long as there is no loop in the inheritance chain.

       Ops tables are finalized when the host is started. NULL or unspecified entries are inherited from the closet ancestor which has the method
       and the entry is populated with it. After finalization, the ops table directly points to all the methods and ->inherits is no longer
       necessary and cleared.

       Using ATA_OP_NULL, inheriting ops can force a method to NULL.

LOCKING

       None.

MEMBERS

       name
	   Identifying name for the regulator.

       supply_name
	   Identifying the regulator supply

       id
	   Numerical identifier for the regulator.

       continuous_voltage_range
	   Indicates if the regulator can set any voltage within constrains range.

       n_voltages
	   Number of selectors available for ops.list_voltage.

       ops
	   Regulator operations table.

       irq
	   Interrupt number for the regulator.

       type
	   Indicates if the regulator is a voltage or current regulator.

       owner
	   Module providing the regulator, used for refcounting.

       min_uV
	   Voltage given by the lowest selector (if linear mapping)

       uV_step
	   Voltage increase with each selector (if linear mapping)

       linear_min_sel
	   Minimal selector for starting linear mapping

       ramp_delay
	   Time to settle down after voltage change (unit: uV/us)

       volt_table
	   Voltage mapping table (if table based mapping)

       vsel_reg
	   Register for selector when using regulator_regmap_X_voltage_

       vsel_mask
	   Mask for register bitfield used for selector

       apply_reg
	   Register for initiate voltage change on the output when using regulator_set_voltage_sel_regmap

       apply_bit
	   Register bitfield used for initiate voltage change on the output when using regulator_set_voltage_sel_regmap

       enable_reg
	   Register for control when using regmap enable/disable ops

       enable_mask
	   Mask for control when using regmap enable/disable ops

       enable_is_inverted
	   A flag to indicate set enable_mask bits to disable when using regulator_enable_regmap and friends APIs.

       bypass_reg
	   Register for control when using regmap set_bypass

       bypass_mask
	   Mask for control when using regmap set_bypass

       enable_time
	   Time taken for initial enable of regulator (in uS).

DESCRIPTION

       Each regulator registered with the core is described with a structure of this type and a struct regulator_config. This structure contains
       the non-varying parts of the regulator description.
