Add interrupts and interrupt-names protperties for PRU and RTU cores. Signed-off-by: MD Danish Anwar <danishanwar@xxxxxx> --- Changes from v1 to v2: *) Added reference of ti,pruss-intc.yaml schema in the description of interrupts property as suggested by Conor. *) Rebased on latest next-20230809 linux-next. v1: https://lore.kernel.org/all/20230807110836.2612730-1-danishanwar@xxxxxx/ .../bindings/remoteproc/ti,pru-rproc.yaml | 23 +++++++++++++++++++ 1 file changed, 23 insertions(+) diff --git a/Documentation/devicetree/bindings/remoteproc/ti,pru-rproc.yaml b/Documentation/devicetree/bindings/remoteproc/ti,pru-rproc.yaml index cd55d80137f7..fc81ba2ad2da 100644 --- a/Documentation/devicetree/bindings/remoteproc/ti,pru-rproc.yaml +++ b/Documentation/devicetree/bindings/remoteproc/ti,pru-rproc.yaml @@ -66,6 +66,17 @@ properties: Should contain the name of the default firmware image file located on the firmware search path. + interrupts: + maxItems: 1 + description: + Interrupt specifiers enable the virtio/rpmsg communication between MPU + and the PRU/RTU cores.
