From 1980eb9bd7d733ce089f9b154c08c2c71fb1f2a7 Mon Sep 17 00:00:00 2001 From: Jaedon Shin Date: Thu, 26 Nov 2015 11:56:29 +0900 Subject: [PATCH] ata: ahci_brcmstb: add support for MIPS-based platforms The BCM7xxx ARM-based and MIPS-based platforms share a similar hardware block for AHCI SATA3. This new compatible string, "brcm,bcm7425-ahci", may be used for most MIPS-based platforms of 40nm process technology.
