1 * Freescale i.MX6 PCIe interface
3 This PCIe host controller is based on the Synopsis Designware PCIe IP
4 and thus inherits all the common properties defined in designware-pcie.txt.
7 - compatible: "fsl,imx6q-pcie"
8 - reg: base addresse and length of the pcie controller
9 - interrupts: A list of interrupt outputs of the controller. Must contain an
10 entry for each entry in the interrupt-names property.
11 - interrupt-names: Must include the following entries:
12 - "msi": The interrupt that is asserted when an MSI is received
13 - clock-names: Must include the following additional entries:
17 - fsl,tx-deemph-gen1: Gen1 De-emphasis value. Default: 0
18 - fsl,tx-deemph-gen2-3p5db: Gen2 (3.5db) De-emphasis value. Default: 0
19 - fsl,tx-deemph-gen2-6db: Gen2 (6db) De-emphasis value. Default: 20
20 - fsl,tx-swing-full: Gen2 TX SWING FULL value. Default: 127
21 - fsl,tx-swing-low: TX launch amplitude swing_low value. Default: 127
