276 	 * Only enable PCIe tunneling if the parent router supports it  in usb4_switch_setup()
299  * @sw: USB4 router
301  * Sets configuration valid bit for the router. Must be called before
302  * any tunnels can be set through the router and after
331  * usb4_switch_read_uid() - Read UID from USB4 router
332  * @sw: USB4 router
335  * Reads 64-bit UID from USB4 router config space.
364  * usb4_switch_drom_read() - Read arbitrary bytes from USB4 router DROM
365  * @sw: USB4 router
370  * Uses USB4 router operations to read router DROM. For devices this

485  * usb4_switch_set_sleep() - Prepare the router to enter sleep
486  * @sw: USB4 router
488  * Sets sleep bit for the router. Returns when the router sleep ready
512  * usb4_switch_nvm_sector_size() - Return router NVM sector size
513  * @sw: USB4 router
515  * If the router supports NVM operations this function returns the NVM
558  * usb4_switch_nvm_read() - Read arbitrary bytes from router NVM
559  * @sw: USB4 router
564  * Reads NVM contents of the router. If NVM is not supported returns
