Detailed Description

Delegates the specified flow to another host for configuration. Only the original owner of the flow, as specified in the RM board configuration resource entries, can delegate an additional host as able to configure the flow. A flow's delegation can be cleared by the original owner of the flow using the clear parameter.

Parameters

hdr	Standard TISCI header
valid_params	Bitfield defining validity of flow delegation parameters. The flow delegation fields are not valid, and will not be used, if their corresponding valid bit is zero. Valid bit usage: 0 - Valid bit for tisci_msg_rm_udmap_flow_delegate_req::delegated_host 1 - Valid bit for tisci_msg_rm_udmap_flow_delegate_req::clear
dev_id	SoC device ID of DMA in which the common flow exists.
flow_index	DMA common flow being delegated for configuration.
delegated_host	The host delegated configuration access to the flow. The host must be a valid host within the SoC. This field is only valid if TISCI_MSG_VALUE_RM_UDMAP_FLOW_DELEGATE_HOST_VALID is set in tisci_msg_rm_udmap_flow_delegate_req::valid_params.
clear	Clears the flow delegation when enabled. Set this parameter to TISCI_MSG_VALUE_RM_UDMAP_FLOW_DELEGATE_CLEAR. This field is only valid if TISCI_MSG_VALUE_RM_UDMAP_FLOW_DELEGATE_CLEAR_VALID is set in tisci_msg_rm_udmap_flow_delegate_req::valid_params.
