$ref: /schemas/types.yaml#/definitions/phandle
description:
A phandle to a syscon device (see ../mfd/syscon.txt) used to access
core corecfg registers. Offsets of registers in this syscon are
determined based on the main compatible string for the device.
clock-output-names:

description:
Name of the card clock which will be exposed by this device.
'#clock-cells':
enum: [0, 1]
description:
With this property in place we will export one or two clocks
representing the Card Clock. These clocks are expected to be
consumed by our PHY.
xlnx,fails-without-test-cd:
$ref: /schemas/types.yaml#/definitions/flag
description:
When present, the controller doesn't work when the CD line is not
connected properly, and the line is not connected properly.
Test mode can be used to force the controller to function.
xlnx,int-clock-stable-broken:
$ref: /schemas/types.yaml#/definitions/flag
description:
When present, the controller always reports that the internal clock
is stable even when it is not.
xlnx,mio-bank:
$ref: /schemas/types.yaml#/definitions/uint32
enum: [0, 1, 2]
default: 0
description:
The MIO bank number in which the command and data lines are configured.
