Geert Uytterhoeven bc30c15f27 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.

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.
