* Freescale i.MX AHCI SATA Controller The Freescale i.MX SATA controller mostly conforms to the AHCI interface with some special extensions at integration level. Required properties: - compatible : should be one of the following: - "fsl,imx53-ahci" for i.MX53 SATA controller - "fsl,imx6q-ahci" for i.MX6Q SATA controller - "fsl,imx6qp-ahci" for i.MX6QP SATA controller - interrupts : interrupt mapping for SATA IRQ - reg : registers mapping - clocks : list of clock specifiers, must contain an entry for each required entry in clock-names - clock-names : should include "sata", "sata_ref" and "ahb" entries Optional properties: - fsl,transmit-level-mV : transmit voltage level, in millivolts. - fsl,transmit-boost-mdB : transmit boost level, in milli-decibels - fsl,transmit-atten-16ths : transmit attenuation, in 16ths - fsl,receive-eq-mdB : receive equalisation, in milli-decibels Please refer to the technical documentation or the driver source code for the list of legal values for these options. - fsl,no-spread-spectrum : disable spread-spectrum clocking on the SATA link. Examples: sata@2200000 { compatible = "fsl,imx6q-ahci"; reg = <0x02200000 0x4000>; interrupts = <0 39 IRQ_TYPE_LEVEL_HIGH>; clocks = <&clks IMX6QDL_CLK_SATA>, <&clks IMX6QDL_CLK_SATA_REF_100M>, <&clks IMX6QDL_CLK_AHB>; clock-names = "sata", "sata_ref", "ahb"; };
