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.
