Subject: [PATCH] ata: Add Qualcomm ARM SoC AHCI SATA host controller driver
|
||||
|
||||
Add support for the Qualcomm AHCI SATA controller that exists on several
|
||||
SoC and specifically the IPQ806x family of chips. The IPQ806x SATA support
|
||||
requires the associated IPQ806x SATA PHY Driver to be enabled as well.
