Aswath Govindraju	e4d4371253	phy: phy-can-transceiver: Add support for setting mux ... On some boards, for routing CAN signals from controller to transceiver, muxes might need to be set. Therefore, add support for setting the mux by reading the mux-states property from the device tree node.

Aswath Govindraju	be24d24840	phy: phy-can-transceiver: Make devm_gpiod_get optional ... In some cases the standby/enable gpio can be pulled low/high and would not be connected to a gpio. The current driver implementation will return an error in these cases. Therefore, make devm_gpiod_get optional.

Aswath Govindraju	a4a86d273f	phy: phy-can-transceiver: Add support for generic CAN transceiver driver ... The driver adds support for generic CAN transceivers. Currently the modes supported by this driver are standby and normal modes for TI TCAN1042 and TCAN1043 CAN transceivers. The transceiver is modelled as a phy with pins controlled by gpios, to put the transceiver in various device functional modes. It also gets the phy attribute max_link_rate for the usage of CAN drivers.
