Subject[PATCH 0/4] CAN TRANSCEIVER: Add support for CAN transceivers
Date
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.
