ata_timing_cycle2mode: find xfer mode for the specified cycle duration
ata_timing_cycle2mode - find xfer mode for the specified cycle duration
u8 ata_timing_cycle2mode(unsigned int
xfer_shift, int cycle);
- ATA_SHIFT_* value for transfer type to examine.
- cycle duration in ns
Return matching xfer mode for cycle. The returned mode is of the transfer type specified by xfer_shift. If cycle is too slow for xfer_shift, 0xff is returned. If cycle is faster than the fastest known mode, the fasted mode is returned.
