230  * @sw: USB4 router to setup
239  * This does not set the configuration valid bit of the router. To do
278 	 * Only enable PCIe tunneling if the parent router supports it  in usb4_switch_setup()
301  * @sw: USB4 router
303  * Sets configuration valid bit for the router. Must be called before
304  * any tunnels can be set through the router and after
333  * usb4_switch_read_uid() - Read UID from USB4 router
334  * @sw: USB4 router
337  * Reads 64-bit UID from USB4 router config space.
366  * usb4_switch_drom_read() - Read arbitrary bytes from USB4 router DROM
367  * @sw: USB4 router
372  * Uses USB4 router operations to read router DROM. For devices this

388  * established with the upstream router. Call only for device routers.
406  * @sw: USB4 router
409  * Enables/disables router to wake up from sleep.

487  * usb4_switch_set_sleep() - Prepare the router to enter sleep
488  * @sw: USB4 router
490  * Sets sleep bit for the router. Returns when the router sleep ready
514  * usb4_switch_nvm_sector_size() - Return router NVM sector size
515  * @sw: USB4 router
517  * If the router supports NVM operations this function returns the NVM
560  * usb4_switch_nvm_read() - Read arbitrary bytes from router NVM
561  * @sw: USB4 router
566  * Reads NVM contents of the router. If NVM is not supported returns
578  * @sw: USB4 router
620  * usb4_switch_nvm_write() - Write to the router NVM
621  * @sw: USB4 router
626  * Writes @buf to the router NVM using USB4 router operations. If NVM

647  * function triggers NVM authentication process. The router gets power

662 	 * The router is power cycled once NVM_AUTH is started so it is  in usb4_switch_nvm_authenticate()
677  * @sw: USB4 router
681  * authenticate router operation. If there is status then %0 is returned
685  * Must be called before any other router operation.
