The delay between deassertion and re-assertion looks good, too. It allows for propagation of the change through the hardware. Those who need longer pauses still can construct individual messages. There's probably no need to change the boolean "cs_change" into a numerical "deassertion pause length" spec.
I'm more worried about board specific requirements to increase the delay there than I am about devices, or about devices that wish to lower the delay. But I do think it's likely to be OK in practice, someone who actually runs into problems can worry about enhancements.
