isci: Add support for user parameters in SCIC layer
Add support for the following parameters in SCIC: /** * This field specifies the NOTIFY (ENABLE SPIN UP) primitive * insertion frequency for this phy index. */ u32 notify_enable_spin_up_insertion_frequency; /** * This method specifies the number of transmitted DWORDs within which * to transmit a single ALIGN primitive. This value applies regardless * of what type of device is attached or connection state. A value of * 0 indicates that no ALIGN primitives will be inserted. */ u16 align_insertion_frequency; /** * This method specifies the number of transmitted DWORDs within which * to transmit 2 ALIGN primitives. This applies for SAS connections * only. A minimum value of 3 is required for this field. */ u16 in_connection_align_insertion_frequency; Signed-off-by: Krzysztof Wierzbicki <Krzysztof.Wierzbicki@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
