Description

Our current I2C FSM does not support disabling the host mode in a graceful way. We should cover this in case multi-host becomes supported. This issue is an icebox for a TODO in the RTL:

opentitan/hw/ip/i2c/rtl/i2c_fsm.sv

Line 1299 in 902088b

// TODO: It may be worth having a force stop condition to force the host back to

Multi-host is currently not planned for PROD, hence leaving this in the backlog.
