title: AHCI SATA Controller
|
||
|
|
|
||
|
|
description: |
|
||
|
|
SATA nodes are defined to describe on-chip Serial ATA controllers.
|
||
|
|
Each SATA controller should have its own node.
|
||
|
|
|
||
|
|
It is possible, but not required, to represent each port as a sub-node.
|
||
|
|
It allows to enable each port independently when dealing with multiple
|
||
|
|
PHYs.
