4670ba6c9e doc: usb: ci-hdrc-usb2: add property non-zero-ttctrl-ttha
If this property is not set, the max packet size is 1023 bytes, and if
the total of packet size for pervious transactions are more than 256 bytes,
it can't accept any transactions within this frame. The use case is single
transaction, but higher frame rate.

If this property is set, the max packet size is 188 bytes, it can handle
more transactions than above case, it can accept transactions until it
considers the left room size within frame is less than 188 bytes, software
needs to make sure it does not send more than 90%
maximum_periodic_data_per_frame. The use case is multiple transactions, but
less frame rate.

9d062b9b41 dt-bindings: Consolidate ChipIdea USB ci13xxx bindings
Combine the ChipIdea USB binding into a single document to reduce
duplication and fragmentation. This marks use of the old PHY bindings as
deprecated. Future compatible bindings should use generic PHY binding.
