Data Fields
ra8_i3c_i2c_complete_fn_t	cb
	Callback or NULL.
void *	ctx
	Callback context.
bool	initialized
	Tracks ra8_i3c_i2c_init / ra8_i3c_i2c_deinit.
bool	bus_held
	True when the previous transaction returned with restart=true and the next call must inject a RESTART instead of a fresh START.

Detailed Description

Per-channel dispatch state shared across the driver's TUs.

Tracks the registered completion callback, its context, the initialization flag, and the held-bus flag used to inject a RESTART instead of a fresh START on a chained transaction. Defined as the s_iic_b_state table in ra8_i3c_i2c.c.

Invariant

bus_held is true only between a restart=true transaction and the next chained call on the same channel.
