+description: |
+ The QCA7000 is a serial-to-powerline bridge with a host interface which could
+ be configured either as SPI or UART slave. This configuration is done by
+ the QCA7000 firmware.
+
+ (a) Ethernet over SPI
+
+ In order to use the QCA7000 as SPI device it must be defined as a child of a
+ SPI master in the device tree.
+
+ (b) Ethernet over UART
+
+ In order to use the QCA7000 as UART slave it must be defined as a child of a
+ UART master in the device tree. It is possible to preconfigure the UART
+ settings of the QCA7000 firmware, but it's not possible to change them during
+ runtime

+ description:
+ Set the SPI data transfer of the QCA7000 to legacy mode.
+ In this mode the SPI master must toggle the chip select
+ between each data word. In burst mode these gaps aren't
+ necessary, which is faster. This setting depends on how
+ the QCA7000 is setup via GPIO pin strapping. If the
+ property is missing the driver defaults to burst mode.
