    libata: normalize port_info, port_operations and sht tables · 6bd99b4e
    Tejun Heo 提交于
    Over the time, port info, ops and sht structures developed quite a bit
    of inconsistencies.  This patch updates drivers.
    
    * Enable/disable_pm callbacks added to all ahci ops tables.
    
    * Every driver for SFF controllers now uses ata_sff_port_start()
      instead of ata_port_start() unless the driver has custom
      implementation.
    
    * Every driver for SFF controllers now uses ata_pci_default_filter()
      unless the driver has custom implementation.
    
    * Removed an odd port_info->sht initialization from ata_piix.c.
      Likely a merge byproduct.
    
    * A port which has ATA_FLAG_SATA set doesn't need to set cable_detect
      to ata_cable_sata().  Remove it from via and mv port ops.
    
    * Some drivers had unnecessary .max_sectors initialization which is
      ignored and was missing .slave_destroy callback.  Fixed.
    
    * Removed unnecessary sht initializations port_info's.
    
    * Removed onsolete scsi device suspend/resume callbacks from
      pata_bf54x.
    
    * No reason to set ata_pci_default_filter() and bmdma functions for
      PIO-only drivers.  Remove those callbacks and replace
      ata_bmdma_irq_clear with ata_noop_irq_clear.
    
    * pata_platform sets port_start to ata_dummy_ret0.  port_start can
      just be set to NULL.
    
    * sata_fsl supports NCQ but was missing qc_defer.  Fixed.
    
    * pata_rb600_cf implements dummy port_start.  Removed.
