Lantiq Synchronous Serial Controller (SSC) SPI master driver
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: "lantiq,ase-spi", "lantiq,falcon-spi", "lantiq,xrx100-spi",
|
||
|
|
"intel,lgm-spi"
|
||
|
|
- #address-cells: see spi-bus.txt
|
||
|
|
- #size-cells: see spi-bus.txt
|
||
|
|
- reg: address and length of the spi master registers
|
||
|
|
- interrupts:
|
||
|
|
For compatible "intel,lgm-ssc" - the common interrupt number for
|
||
|
|
all of tx rx & err interrupts.
|
||
|
|
or
|
||
|
|
For rest of the compatibles, should contain the "spi_rx", "spi_tx" and
|
||
|
|
"spi_err" interrupt.
|
||
|
|
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- clocks: spi clock phandle
|
||
|
|
- num-cs: see spi-bus.txt, set to 8 if unset
|
||
|
|
- base-cs: the number of the first chip select, set to 1 if unset.
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
