fsl_add_outb_message - Add message to the MPC85xx outbound message queue : Master port with outbound message queue : Target of outbound message : Outbound mailbox : Message to add to outbound queue : Length of message
Adds the message to the MPC85xx outbound message queue. Returns %0 on success or %-EINVAL on failure.
fsl_open_inb_mbox - Initialize MPC85xx inbound mailbox : Master port implementing the inbound message unit : Device specific pointer to pass on event : Mailbox to open : Number of entries in the inbound mailbox ring
Initializes buffer ring, request the inbound message interrupt, and enables the inbound message unit. Returns %0 on success and %-EINVAL or %-ENOMEM on failure.
fsl_open_outb_mbox - Initialize MPC85xx outbound mailbox : Master port implementing the outbound message unit : Device specific pointer to pass on event : Mailbox to open : Number of entries in the outbound mailbox ring
Initializes buffer ring, request the outbound message interrupt, and enables the outbound message unit. Returns %0 on success and %-EINVAL or %-ENOMEM on failure.
| int fsl_rio_doorbell_init | ( | struct fsl_rio_dbell * | dbell | ) |
fsl_rio_doorbell_init - MPC85xx doorbell interface init : Master port implementing the inbound doorbell unit
Initializes doorbell unit hardware and inbound DMA buffer ring. Called from fsl_rio_setup(). Returns %0 on success or %-ENOMEM on failure.
fsl_rio_doorbell_send - Send a MPC85xx doorbell message : RapidIO master port info : ID of RapidIO interface : Destination ID of target device : 16-bit info field of RapidIO doorbell message
Sends a MPC85xx doorbell message. Returns %0 on success or %-EINVAL on failure.
| int fsl_rio_port_write_init | ( | struct fsl_rio_pw * | pw | ) |
fsl_rio_port_write_init - MPC85xx port write interface init : Master port implementing the port write unit
Initializes port write unit hardware and DMA buffer ring. Called from fsl_rio_setup(). Returns %0 on success or %-ENOMEM on failure.
