      "message": "[PATCH] libata-hp-prep: add prereset() method and implement ata_std_prereset()\n\nWith hotplug, every reset might be a probing reset and thus something\nsimilar to probe_init() is needed.  prereset() method is called before\na series of resets to a port and is the counterpart of postreset().\nprereset() can tell EH to use different type of reset or skip reset by\nmodifying ehc-\u003ei.action.\n\nThis patch also implements ata_std_prereset().  Most controllers\nshould be able to use this function directly or with some wrapping.\nAfter hotplug, different controllers need different actions to resume\nthe PHY and detect the newly attached device.  Controllers can be\ncategorized as follows.\n\n* Controllers which can wait for the first D2H FIS after hotplug.\n  Note that if the waiting is implemented by polling TF status, there\n  needs to be a way to set BSY on PHY status change.  It can be\n  implemented by hardware or with the help of the driver.\n\n* Controllers which can wait for the first D2H FIS after sending\n  COMRESET.  These controllers need to issue COMRESET to wait for the\n  first FIS.  Note that the received D2H FIS could be the first D2H\n  FIS after POR (power-on-reset) or D2H FIS in response to the\n  COMRESET.  Some controllers use COMRESET as TF status\n  synchronization point and clear TF automatically (sata_sil).\n\n* Controllers which cannot wait for the first D2H FIS reliably.\n  Blindly issuing SRST to spinning-up device often results in command\n  issue failure or timeout, causing extended delay.  For these\n  controllers, ata_std_prereset() explicitly waits ATA_SPINUP_WAIT\n  (currently 8s) to give newly attached device time to spin up, then\n  issues reset.  Note that failing to getting ready in ATA_SPINUP_WAIT\n  is not critical.  libata will retry.  So, the timeout needs to be\n  long enough to spin up most devices.\n\nLLDDs can tell ata_std_prereset() which of above action is needed with\nATA_FLAG_HRST_TO_RESUME and ATA_FLAG_SKIP_D2H_BSY flags.  These flags\nare PHY-specific property and will be moved to ata_link later.\n\nWhile at it, this patch unifies function typedef\u0027s such that they all\nhave named arguments.\n\nSigned-off-by: Tejun Heo \u003chtejun@gmail.com\u003e\n"
