| struct dt_desc_rv_plic |
| Data Fields | ||
|---|---|---|
| dt_clock_t | clock[kDtRvPlicClockCount] | Clock signal connected to each clock port. |
| top_darjeeling_alert_id_t | first_alert |
Alert ID of the first Alert of this instance. This value is undefined if the block is not connected to the Alert Handler. |
| top_earlgrey_alert_id_t | first_alert |
Alert ID of the first Alert of this instance. This value is undefined if the block is not connected to the Alert Handler. |
| dt_instance_id_t | inst_id | Instance ID. |
| uint32_t | reg_addr[kDtRvPlicRegBlockCount] | Base address of each register block. |
| dt_reset_t | reset[kDtRvPlicResetCount] | Reset signal connected to each reset port. |
| #define TRY_GET_DT | ( | dt, | |
| default ) |
Return a pointer to the dt_rv_plic_desc_t structure of the requested dt if it's a valid index.
Otherwise, this macro will return (i.e. exit the function) with the provided default value.
| dt_clock_t dt_rv_plic_clock | ( | dt_rv_plic_t | dt, |
| dt_rv_plic_clock_t | clk ) |
| dt_rv_plic_t dt_rv_plic_from_instance_id | ( | dt_instance_id_t | inst_id | ) |
Get the rv_plic instance from an instance ID.
For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.
| inst_id | Instance ID. |
Note: This function only makes sense if the instance ID has device type rv_plic, otherwise the returned value is unspecified.
