.SH "NAME"
ata_timing_cycle2mode \- find xfer mode for the specified cycle duration
.SH "SYNOPSIS"

.BI "u8 ata_timing_cycle2mode(unsigned\ int\ " "xfer_shift" ", int\ " "cycle" ");"
.SH "ARGUMENTS"
.PP
\fIxfer_shift\fR
.RS 4
ATA_SHIFT_* value for transfer type to examine\&.
.RE
.PP
\fIcycle\fR
.RS 4
cycle duration in ns

.SH "DESCRIPTION"
.PP
Return matching xfer mode for
\fIcycle\fR\&. The returned mode is of the transfer type specified by
\fIxfer_shift\fR\&. If
\fIcycle\fR
is too slow for
\fIxfer_shift\fR, 0xff is returned\&. If
\fIcycle\fR
is faster than the fastest known mode, the fasted mode is returned\&.
.PP
LOCKING: None\&.
.SH "RETURN"
.PP
Matching xfer_mode, 0xff if no match found\&.
