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
28 		      between each data word. In burst mode these gaps aren't
31 		      property is missing the driver defaults to burst mode.
