tcan4552 and tcan4553 do not have wake or state pins, so they are
currently not compatible with the generic driver. The generic driver
uses tcan4x5x_disable_state() and tcan4x5x_disable_wake() if the gpios
are not defined. These functions use register bits that are not
available in tcan4552/4553.
This patch adds support by introducing version information to reflect if
the chip has wake and state pins. Also the version is now checked.

This is a preparation for adding

On AM62x SoC, MCANs on MCU domain do not have hardware interrupt

Add an hrtimer to MCAN class device. Each MCAN will have its own
hrtimer instantiated if there is no hardware interrupt found in
device tree M_CAN node. The timer will generate a software

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart from
emitting a warning) and this typically results in resource leaks. To improve
here there is a quest to make the remove callback return void. In the first
step of this quest all drivers are converted to .remove_new() which already
returns void. Eventually after all drivers are converted, .remove_new() is
renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Interrupts currently get disabled if the interrupt status shows new
received data. Non-peripheral chips handle receiving in a worker thread,
but peripheral chips are handling the receive process in the threaded
interrupt routine itself without scheduling it for a different worker.
So there is no need to disable interrupts for peripheral chips.

Currently, some CAN drivers support hardware timestamping, some do
not. But userland has no method to query which features are supported
(aside maybe of getting RX messages and observe whether or not
hardware timestamps stay at zero).
The canonical way for a network driver to advertised what kind of
timestamping it supports is to implement ethtool_ops::get_ts_info().
This patch only targets the CAN drivers which *do not* support
hardware timestamping. For each of those CAN drivers, implement the
get_ts_info() using the generic ethtool_op_get_ts_info().
This way, userland can do:
| $ ethtool --show-time-stamping canX
to confirm the device timestamping capacities.
N.B. the drivers which support hardware timestamping will be migrated
in separate patches.

can_rx_offload_queue_timestamp(). This better describes what the
function does, it adds a newly RX'ed skb to the sorted queue by its
timestamp.
