Please add a patch that adds the driver and the bindings to the MAINTAINERS file. Feel free to add it CAN NETWORK DRIVERS. regards, Marc
The following series of patches add support for CAN transceivers. 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.
