## NAME

sata\_link\_hardreset - reset link via SATA phy reset

## SYNOPSIS

**int sata\_link\_hardreset(struct ata\_link \*** *link***, const unsigned long \*** *timing***, unsigned long** *deadline***, bool \*** *online***, int (\****check\_ready***) (struct ata\_link \*));**

## ARGUMENTS

*link*

link to reset

*timing*

timing parameters { interval, duration, timeout } in msec

*deadline*

deadline jiffies for the operation

*online*

optional out parameter indicating link onlineness

*check\_ready*

## DESCRIPTION

SATA phy-reset *link* using DET bits of SControl register. After hardreset, link readiness is waited upon using **ata\_wait\_ready** if *check\_ready* is specified. LLDs are allowed to not specify *check\_ready* and wait itself after this function returns. Device classification is LLD's responsibility.

\**online* is set to one iff reset succeeded and *link* is online after reset.
