3 The QCA7000 is a serial-to-powerline bridge with a host interface which could
4 be configured either as SPI or UART slave. This configuration is done by
7 (a) Ethernet over SPI
9 In order to use the QCA7000 as SPI device it must be defined as a child of a
10 SPI master in the device tree.
13 - compatible	    : Should be "qca,qca7000"
14 - reg		    : Should specify the SPI chip select
15 - interrupts	    : The first cell should specify the index of the source
18 - spi-cpha	    : Must be set
19 - spi-cpol	    : Must be set
22 - spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at.
24 		      are invalid. Missing the property will set the SPI
26 - qca,legacy-mode   : Set the SPI data transfer of the QCA7000 to legacy mode.
27 		      In this mode the SPI master must toggle the chip select
