+Subject: [PATCH 1/3] ahci: Annotate PCI ids for mobile Intel chipsets as such
+
+Intel uses different SATA PCI ids for the Desktop and Mobile SKUs of their
+chipsets. For older models the comment describing which chipset the PCI id
+is for, aksi indicates when we're dealing with a mobile SKU. Extend the
+comments for recent chipsets to also indicate mobile SKUs.
+
+The information this commit adds comes from Intel's chipset datasheets.
+
+This commit is a preparation patch for allowing a different default
+sata link powermanagement policy for mobile chipsets.
