This driver implements `read`, `write`, `open`, `close` and `ioctl`
interfaces to the SHT4X temperature and humidity sensor on an I2C bus.
The read implementation is that of a character driver for easy
debugging, while `ioctl` provides an interface to the sensor's raw data
collection and heating functionality.

Original documentation link for riscv is broken,
so update to the correct link for all architectures.
Put the link around `reg_off` to avoid the long line warning

This adds field type to canioc_bittiming_s structure that allows
to set/obtain bit timing for both CAN CC and CAN FD.
CANIOC_GET_BITTIMING is now bidirectional: user specifies type field
and gets other fields from the controller.
The commit also updates current CAN FD capable controllers using the
ioctl. The type is not checked for classical CAN only controllers
and nominal bit timing is returned regardless of type value.

This commit moves can_bytes2dlc and can_dlc2bytes from kernel internal
functions to API. These functions are necessary to convert bytes to
dlc for CAN FD frames and has to be accessible from the application
since can_hdr_s does not store message length in bytes but directly in
dlc.

we can use g_cpu_lockset to determine whether we are currently in the scheduling lock,
and all accesses and modifications to g_cpu_lockset, g_cpu_irqlock, g_cpu_irqset
are in the critical section, so we can directly operate on it.

We can use qemu for testing.

If the CAN stack receiving packets fast, but the application layer reading packets slow. Then `conn->readahead` will continue to grow, leading to memory leaks. Finally CAN stack potentially starve out all IOB buffers. To prevent memory leaks, users can restrict can socket buffer length.
