SYNOPSIS

9       int sata_link_hardreset(struct ata_link * link,
10                               const unsigned long * timing,
11                               unsigned long deadline, bool * online,
12                               int (*check_ready) (struct ata_link *));

ARGUMENTS

15       link
16           link to reset
17
18       timing
19           timing parameters { interval, duratinon, timeout } in msec
20
21       deadline
22           deadline jiffies for the operation
23
24       online
25           optional out parameter indicating link onlineness
26
27       check_ready
28           optional callback to check link readiness

DESCRIPTION

31       SATA phy-reset link using DET bits of SControl register. After
32       hardreset, link readiness is waited upon using ata_wait_ready if
33       check_ready is specified. LLDs are allowed to not specify check_ready
34       and wait itself after this function returns. Device classification is
35       LLD's responsibility.
36
37       *online is set to one iff reset succeeded and link is online after
38       reset.
