Calculate how long an I2C transation will take in microseconds, and use
this as the timeout for mpfs_i2c_sem_waitdone.
The reason for doing this is not to keep an i2c bus reserved for the full
1 second timeout, if e.g. a sensor is not on the bus / is faulty and
non-responsive. Reading the other sensors will be blocked for a relatively
long time (1 second) in this case. This fixes such behavior.
update LIBFDT to LIBC_FDT
update CONFIG_LIBFDT_DTC_VERSION to CONFIG_LIBC_FDT_DTC_VERSION
move dtc source code to fdt/dtc
move version_gen.h from apps/system/fdt to current dir

This patch starts to implement the ability to build Meadow.OS for the Meadow F7 board with the NuttX mainline. It will be followed by more patches, progressively enabling full Meadow.OS functionality. This configuration is a work in progress.
The Meadow.OS source code is needed to build this configuration. Meadow.OS is being open-sourced under the Apache 2.0 license. A prototype of the source code release and integration with NuttX is at https://github.com/WildernessLabs/Meadow.OS/tree/prototype
This is the second revision of this patch, as the first one (https://github.com/apache/nuttx/pull/9997) was causing build issues on NuttX CI and was reverted.
This should only impact the Meadow F7 board configurations.
No testing to be done, as the configuration is under development.
Non-blocking sockets are almost never in the connected state when app try to
get result of connect success through poll, to avoid confusion because of
this error print, so downgrade the print level to warning.

IP_MULTICAST_IF (since Linux 1.2)
Set the local device for a multicast socket. The argument
for setsockopt(2) is an ip_mreqn or (since Linux 3.5)
ip_mreq structure similar to IP_ADD_MEMBERSHIP, or an
in_addr structure. (The kernel determines which structure
is being passed based on the size passed in optlen.) For
getsockopt(2), the argument is an in_addr structure.
refer to https://man7.org/linux/man-pages/man7/ipv6.7.html
IPV6_MULTICAST_IF
Set the device for outgoing multicast packets on the
socket. This is allowed only for SOCK_DGRAM and SOCK_RAW
socket. The argument is a pointer to an interface index
(see netdevice(7)) in an integer.

Move SCU-specific ak09912 sensor into spresense board layer.
Rename a function name to register SCU sensor driver
from ak09912_register to ak09912_scu_register.
This commit adds function pwm_set_polarity() that setups channel
polarity based on input info from application layer.
Signed-off-by: Michal Lenc <michallenc@seznam.cz>
Channel polarity can now be set with PWMIOC_SETCHARACTERISTICS ioctl
command as field cpol was added to pwm_info_s structure. This way the
polarity can be easily set from application layer for each channel
apart and also can be change on at runtime if required (although this is
not likely).
Helper defines were also added to simplify the definition of low and high
polarity level. Architecture level should take care of writing the
polarity to correct MCU registers.

Using the macro places the buffers into .data section which means they
will consume the full buffer size of flash / read only memory as well.
Place the buffers into .bss to avoid this case.
