1 Qualcomm Universal Peripheral (QUP) Serial Peripheral Interface (SPI)
4 and an input FIFO) for serial peripheral interface (SPI) mini-core.
6 SPI in master mode supports up to 50MHz, up to four chip selects, programmable
10 - compatible: Should contain:
11 "qcom,spi-qup-v1.1.1" for 8660, 8960 and 8064.
12 "qcom,spi-qup-v2.1.1" for 8974 and later
13 "qcom,spi-qup-v2.2.1" for 8974 v2 and later.
15 - reg: Should contain base register location and length
16 - interrupts: Interrupt number used by this controller
18 - clocks: Should contain the core clock and the AHB clock.
19 - clock-names: Should be "core" for the core clock and "iface" for the
22 - #address-cells: Number of cells required to define a chip select
23 address on the SPI bus. Should be set to 1.
24 - #size-cells: Should be zero.
27 - spi-max-frequency: Specifies maximum SPI clock frequency,
28 Units - Hz. Definition as per
29 Documentation/devicetree/bindings/spi/spi-bus.txt
30 - num-cs: total number of chipselects
31 - cs-gpios: should specify GPIOs used for chipselects.
32 The gpios will be referred to as reg = <index> in the SPI child
33 nodes. If unspecified, a single SPI device without a chip
36 - dmas: Two DMA channel specifiers following the convention outlined
38 - dma-names: Names for the dma channels, if present. There must be at
42 SPI slave nodes must be children of the SPI master node and can contain
43 properties described in Documentation/devicetree/bindings/spi/spi-bus.txt
