The AXI SPI Engine has support for hardware offloading capabilities. There can be up to 32 offload instances per SPI controller, so the bindings limit the value accordingly. Signed-off-by: David Lechner <dlechner@baylibre.com> --- v2 changes: This is basically a new patch. It partially replaces "dt-bindings: iio: offload: add binding for PWM/DMA triggered buffer". The controller no longer has an offloads object node and the spi-offloads property is now a standard SPI peripheral property. --- .../devicetree/bindings/spi/adi,axi-spi-engine.yaml | 14 ++++++++++++++ 1 file changed, 14 insertions(+)
