* AHCI SATA Controller SATA nodes are defined to describe on-chip Serial ATA controllers. Each SATA controller should have its own node. Required properties: - compatible : compatible list, contains "calxeda,hb-ahci" or "snps,spear-ahci" - interrupts : <interrupt mapping for SATA IRQ> - reg : <registers mapping> Example: sata@ffe08000 { compatible = "calxeda,hb-ahci"; reg = <0xffe08000 0x1000>; interrupts = <115>; };
