description: |

|
PIO pin configuration for RF, RK, RD, TF, TK, & TD signals.
|
|
We expect that the phandles will reference pinctrl nodes.
|
|
These nodes will have a nodelabel that matches the Atmel SoC HAL
|
|
defines and be of the form p<port><pin><periph>_<inst>_<signal>.
|
|
|
|
For example the SSC on SAME7x would be
|
|
pinctrl-0 = <&pd24b_ssc_rf &pa22a_ssc_rk &pa10c_ssc_rd
|
|
&pb0d_ssc_tf &pb1d_ssc_tk &pb5d_ssc_td>;

dmas:

TX & RX dma specifiers. Each specifier will have a phandle
|
|
reference to the dma controller, the channel number, and peripheral
|
|
trigger source.
|
|
|
|
For example dmas for TX, RX would look like
|
|
dmas = <&xdmac 22 DMA_PERID_SSC_TX>, <&xdmac 23 DMA_PERID_SSC_RX>;
|
|
|
|
dma-names:
|
|
required: true
|
|
description: |
|
|
This should be "tx" and "rx" to match the dmas property.
|
|
|
|
For example
|
|
dma-names = "tx", "rx";
