GENI based Qualcomm Universal Peripheral (QUP) Serial Peripheral Interface (SPI)
The QUP v3 core is a GENI based AHB slave that provides a common data path
(an output FIFO and an input FIFO) for serial peripheral interface (SPI)
mini-core.
SPI in master mode supports up to 50MHz, up to four chip selects, programmable
data path from 4 bits to 32 bits and numerous protocol variants.
Required properties:
- compatible: Must contain "qcom,geni-spi".
- reg: Must contain SPI register location and length.
- interrupts: Must contain SPI controller interrupts.
- clock-names: Must contain "se".
- clocks: Serial engine core clock needed by the device.
- #address-cells: Must be <1> to define a chip select address on
the SPI bus.
- #size-cells: Must be <0>.
SPI Controller nodes must be child of GENI based Qualcomm Universal
Peripharal. Please refer GENI based QUP wrapper controller node bindings
described in Documentation/devicetree/bindings/soc/qcom/qcom,geni-se.txt.
SPI slave nodes must be children of the SPI master node and conform to SPI bus
binding as described in Documentation/devicetree/bindings/spi/spi-bus.txt.
Example:
spi0: spi@a84000 {
