Somewhere you'll need to allocate an entry in CBMEM for this:

cbmem_id.h:
`#define CBMEM_ID_TYPE_C_PORTS 0x54595043 /* TYPC */`
(and the associated string)

and then allocate cbmem here (pseudocode):
```
static void conn_write_cbmem_entry(struct device *dev)
{
       static uint32_t ports_written;
       struct type_c_port_info *ports;

if (!connector_count)
              return;

if (ports_written == 0) {
              size_t entry_size;

entry_size = sizeof(type_c_port_info) * connector_count;
              ports = cbmem_add(CBMEM_ID_TYPE_C_PORTS); 
              if (!ports) print_error_and_return;
       } else {
              ports = cbmem_find(CBMEM_ID_TYPE_C_PORTS);
              if (!ports) print_error_and_return;
       }

const struct drivers_intel_pmc_mux_conn_config *config = config_of(dev);
       memcpy(&ports[ports_written], config, sizeof(*config));
       ports_written++;
};
```
