serial: ifx6x60: expanded info available from platform data
Some platform attributes (e.g. max_hz, use_dma) were being intuited from the modem type. These things should be specified by the platform data. Added max_hz, use_dma to ifx_modem_platform_data definition, replaced is_6160 w/ modem_type, and changed clients accordingly Signed-off-by: Russ Gorby <russ.gorby@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
