phy: phy-can-transceiver: Skip warning if no "max-bitrate"
...
According to the DT bindings, the "max-bitrate" property is optional.
However, when it is not present, a warning is printed.
Fix this by adding a missing check for -EINVAL.

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.

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.

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.
