TCAN1042 has a standby signal that needs to be pulled high for sending/receiving messages[1]. TCAN1043 has a enable signal along with standby signal that needs to be pulled up for sending/receiving messages[2], and other combinations of the two lines can be used to put the transceiver in different states to reduce power consumption. On boards like the AM654-idk and J721e-evm these signals are controlled using gpios. Patch 1 models the transceiver as a phy device tree node with properties for max bit rate supported, gpio properties for indicating gpio pin numbers to which standby and enable signals are connected. Patch 2 adds a generic driver to support CAN transceivers. Patches 3 & 4 add support for implementing the transceiver as a phy of m_can_platform driver.
