[RFC v2 01/10] ath10k: high_latency detection

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The setup of high latency chips (USB and SDIO) is
sometimes different than for chips using low latency
interfaces.

The bus type is used to determine if the interface is
a high latency interface.
