Updates the ADS1115 documentation with information about the two new
commands for triggering conversion and reading the result.
Signed-off-by: Matteo Golin <matteo.golin@gmail.com>
Since the ADS1115 has a relative slow conversion rate, this additional
ioctl command makes it possible to trigger a conversion before reading
the reading the conversion result, allowing the user to perform other
computation in between instead of waiting for the conversion time to
complete. It improves sampling time.

The tx int handler will call uart_xmitchars() to make a fake interrupt event,
but this is unsafe after enabling interrupts. This PR will add a critical section
to ensure that the txint process will not be interrupted by the IRQ

idr_destroy() would loop over the removed and alloced
RB tree nodes freeing them but not removing them from
the trees. From the perspective of the RB tree those
nodes would remain valid, while in fact, they were free
memory, potentially reallocated for other purposes, or
otherwise overwritten by the allocator with metadata.
This would cause (seemingly random) memory corruption
crashes triggered by the RB tree code trying to access
link fields from the free'd nodes.
Fix that by removing the nodes before freeing them.

This commit adds support for the HX711 ADC in the STM32F401RC-RS485
board and updates the board documentation accordingly.

AVR uses Hardward architecture with separate address space for program
memory (flash) and data memory (RAM). Normal program flow can only
access data memory which means that all variables - including const
variables - have to be copied into RAM to be accessible. (This happens
automatically during startup.)
It is possible to work around this limitation in software but that
can have severe impact on performance and/or API complexity. It is hardly
feasible to change NuttX interfaces in a way that would allow to make use
of this workaround.
On newer AVR families, there is an alternative option enabled by this patch.
These chips map part of their program memory (a 32kB window) into data
memory address space. This patch leverages this feature and adds support
for placing const variables into the mapped window. No copy to RAM is done
for them.
Const variables are therefore loaded directly from flash (not consuming
RAM) while still being available to be used by any NuttX interface.
Linker script of breadxavr board is changed to make use of these changes.
Tested by verifying string addresses - parameters in printf call
in a custom application (and also by running the application and verifying
its output.)
Documentation tested by build.

This patch adds a document that describes why const variables need to be
copied into the RAM in AVR architecture for normal program flow in NuttX.
It then describes options of accessing them directly from the flash without
need to do any copying.
Patch was tested by building the documentation.

Added logic to set hasdma to false. This is needed to enable or not enable interrupts on a per ADC basis. Made other minor formatting changes.
Fixed build issues with non ADC/DMA configurations.
This commit removes the termios dependency of the command to set fix
rate. It makes the MINMEA dependency present in the Kconfig options for
the driver, and it also adds a retry limit to the boot message
verification of 3 times. The documentation has been updated to reflect
the correct signature for the registration function and fix some
formatting.

When using the ILI9342C LCD on the esp32s3-box-3 development board, the
displayed colors are inverted.

Manually converts the byte order of color data from little-endian
to big-endian before transmission.
The current setlogmask call used in coredump_dump_syslog specifies a raw log level
instead of a bitmask, and this causes wrong evaluations later on when that value
is checked against a mask. Therefore the LOG_UPTO macro is added for conversion.
