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>; | ||
} |

* Samsung I2S controller | ||
|
||
Required SoC Specific Properties: | ||
|
||
- compatible : "samsung,i2s-v5" | ||
- reg: physical base address of the controller and length of memory mapped | ||
region. | ||
- dmas: list of DMA controller phandle and DMA request line ordered pairs. | ||
- dma-names: identifier string for each DMA request line in the dmas property. | ||
These strings correspond 1:1 with the ordered pairs in dmas. | ||

Optional SoC Specific Properties: | ||
|
||
- samsung,supports-6ch: If the I2S Primary sound source has 5.1 Channel | ||
support, this flag is enabled. | ||
- samsung,supports-rstclr: This flag should be set if I2S software reset bit | ||
control is required. When this flag is set I2S software reset bit will be | ||
enabled or disabled based on need. | ||
- samsung,supports-secdai:If I2S block has a secondary FIFO and internal DMA, | ||
then this flag is enabled. | ||
- samsung,idma-addr: Internal DMA register base address of the audio | ||
sub system(used in secondary sound source). | ||
|
||
Required Board Specific Properties: | ||
|
||
