* Clock bindings for Freescale i.MX31 | ||
|
||
Required properties: | ||
- compatible: Should be "fsl,imx31-ccm" | ||
- reg: Address and length of the register set | ||
- interrupts: Should contain CCM interrupt | ||
- #clock-cells: Should be <1> | ||
|
||
The clock consumer should specify the desired clock by having the clock | ||
ID in its "clocks" phandle cell. The following is a full list of i.MX31 | ||
clocks and IDs. | ||

CSR SiRFprimaII pinmux controller | ||
|
||
Required properties: | ||
- compatible : "sirf,prima2-pinctrl" | ||
- reg : Address range of the pinctrl registers | ||
- interrupts : Interrupts used by every GPIO group | ||
- gpio-controller : Indicates this device is a GPIO controller | ||
- interrupt-controller : Marks the device node as an interrupt controller | ||
Optional properties: | ||
- sirf,pullups : if n-th bit of m-th bank is set, set a pullup on GPIO-n of bank m | ||
- sirf,pulldowns : if n-th bit of m-th bank is set, set a pulldown on GPIO-n of bank m | ||
|
||
Please refer to pinctrl-bindings.txt in this directory for details of the common | ||
pinctrl bindings used by client devices. | ||
|
||
SiRFprimaII's pinmux nodes act as a container for an abitrary number of subnodes. | ||
Each of these subnodes represents some desired configuration for a group of pins. | ||
|
||
Required subnode-properties: | ||
- sirf,pins : An array of strings. Each string contains the name of a group. | ||
- sirf,function: A string containing the name of the function to mux to the | ||
group. | ||
|
||
Valid values for group and function names can be found from looking at the | ||
group and function arrays in driver files: | ||
drivers/pinctrl/pinctrl-sirf.c | ||
|
||
For example, pinctrl might have subnodes like the following: | ||
uart2_pins_a: uart2@0 { | ||
uart { | ||
sirf,pins = "uart2grp"; | ||
sirf,function = "uart2"; | ||
}; | ||
}; | ||
uart2_noflow_pins_a: uart2@1 { | ||
uart { | ||
sirf,pins = "uart2_nostreamctrlgrp"; | ||
sirf,function = "uart2_nostreamctrl"; | ||
}; | ||
}; | ||
|
||
For a specific board, if it wants to use uart2 without hardware flow control, | ||
it can add the following to its board-specific .dts file. | ||
uart2: uart@0xb0070000 { | ||
pinctrl-names = "default"; | ||
pinctrl-0 = <&uart2_noflow_pins_a>; | ||
} |
