Detailed Description

Common UDC driver data structure.

Mandatory structure for each UDC controller driver. To be implemented as device's private data (device->data).

Field Documentation

event_ctx

const void* udc_data::event_ctx

Opaque pointer to store higher layer context.

mutex

struct k_mutex udc_data::mutex

Driver access mutex.

priv
