NAME

       struct_hsi_client - HSI client attached to an HSI port

SYNOPSIS

       struct hsi_client {
	 struct device device;
	 struct hsi_config tx_cfg;
	 struct hsi_config rx_cfg;
       };

MEMBERS

       device
	   Driver model representation of the device

       tx_cfg
	   HSI TX configuration

       rx_cfg
	   HSI RX configuration

E_HANDLER
       Callback for handling port events (RX Wake High/Low)

PCLAIMED

       Keeps tracks if the clients claimed its associated HSI port

NB

       Notifier block for port events
