| * 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"; |
| }; |
