1* Freescale i.MX AHCI SATA Controller 2 3The Freescale i.MX SATA controller mostly conforms to the AHCI interface 4with some special extensions at integration level. 5 6Required properties: 7- compatible : should be one of the following: 8 - "fsl,imx53-ahci" for i.MX53 SATA controller 9 - "fsl,imx6q-ahci" for i.MX6Q SATA controller 10 - "fsl,imx6qp-ahci" for i.MX6QP SATA controller 11- interrupts : interrupt mapping for SATA IRQ 12- reg : registers mapping 13- clocks : list of clock specifiers, must contain an entry for each 14 required entry in clock-names 15- clock-names : should include "sata", "sata_ref" and "ahb" entries 16 17Optional properties: 18- fsl,transmit-level-mV : transmit voltage level, in millivolts. 19- fsl,transmit-boost-mdB : transmit boost level, in milli-decibels 20- fsl,transmit-atten-16ths : transmit attenuation, in 16ths 21- fsl,receive-eq-mdB : receive equalisation, in milli-decibels 22 Please refer to the technical documentation or the driver source code 23 for the list of legal values for these options. 24- fsl,no-spread-spectrum : disable spread-spectrum clocking on the SATA 25 link. 26 27Examples: 28 29sata@2200000 { 30 compatible = "fsl,imx6q-ahci"; 31 reg = <0x02200000 0x4000>; 32 interrupts = <0 39 IRQ_TYPE_LEVEL_HIGH>; 33 clocks = <&clks IMX6QDL_CLK_SATA>, 34 <&clks IMX6QDL_CLK_SATA_REF_100M>, 35 <&clks IMX6QDL_CLK_AHB>; 36 clock-names = "sata", "sata_ref", "ahb"; 37}; 38
