sata_down_spd_limit — adjust SATA spd limit downward
int sata_down_spd_limit ( | struct ata_link * link, |
u32 spd_limit); |
Adjust SATA spd limit of link downward. Note that this
function only adjusts the limit. The change must be applied
using sata_set_spd.
If spd_limit is non-zero, the speed is limited to equal to or
lower than spd_limit if such speed is supported. If
spd_limit is slower than any supported speed, only the lowest
supported speed is allowed.
LOCKING: Inherited from caller.
