In hybrid_corexy and hybrid_corexz, the update_limits function is (only) called by the DualCarriage implementation, whenever the carriage changes.
Unfortunately, these limits also keep track of homing status, when they're unhomed they are set to 1 to -1 (invalid range).
As a fix, if the limit was set to "unhomed", we keep it that way, and only update it with the new rail limits if it was already properly homed before.

Check for untracked files in the klippy/extras/ and klippy/kinematics/
directories and report those files in the log. This helps identify
code modifications when inspecting a log.

New printer : Longer LK4X configuration
This configuration is based on the one provided by Longer with some tweaks.

On a USB bus reset the controller address needs to be reset to zero.
Otherwise, the device becomes unresponsive after a USB reset and will
remain unresponsive until a power cycle. This often shows up in the
Linux system logs as "device descriptor read/64, error -32" messages.
Make sure USB_INTE_BUS_RESET_BITS is enabled and clear the USB address
on a bus reset.

There is no need to heavily prioritize the sending of canbus packets
over USB. A single check to flush the incoming canbus packets is
sufficient.
Also, be sure to wake up canserial_notify_tx() even if canhw_send()
blocks.

The canserial code already advertizes a receive window, so the host
should never flood the canserial code. Remove the extra scheduling
checks to simplify the usb_canbus code.

A buffer of only 8 canbus packets is only 64 bytes of data, which
could be exceeded if the usb-to-canbus mcu gets busy doing other work.
Increase the buffer to 32 packets.

The DAINTMSK prevents irqs but does not prevent the status reporting
in the GINTSTS and DAINT fields. Thus, the mask bits should be
checked prior to sending a wakeup notification.

The control bytes for the AHT20 and AHT21 are identical to the AHT10, but I had not been able to test just yet to ensure the sensor code supported the other sensors. I've wrapped up testing and updated the comments/docs to reflect this additional support.

Fixes common MPU-9250 accelerometer issues for RPi Linux MCU and
improves reliability on all other architectures by adjusting the MPU-*
reading algorithm to only read whole Klipper messages' worth of
data from MPU-* and eliminating many unnecessary checks of the MPU FIFO
fill-level that consumed bus bandwidth needed for data transfer. Fixes
intermittent "Lost communication with MCU 'rpi'" due to "Timer too
close" and transposed / corrupted data due to FIFO overrun/data loss
when using MPU-* accelerometers. In addition FIFO overrun checks are
performed by testing the MPU interrupt flag vs. inferring from the FIFO
fill level.
Stress tested for 13hrs with two MPU-6500 attached to one I2C bus on RPi
and one on a PR2040

The stalled_bytes counter refers to the number of bytes that are not
yet eligible for transmission. However, the naming leads to confusion
as it could be interpretted as an inability to transmit data. Rename
to upcoming_bytes to try to avoid that confusion.

This commit adds support for the I2C-based AHT10 ambient temperature sensor. The sensor comes pre-calibrated and has a fairly simple command interface, so the interface class is in-turn relatively simple. So far this has been tested on a BTT GTR 1.0 MCU board (STM32F4), and seems to work fine.

As found on the discord by user Qtin, this board now ships with one of STM32H743 or STM32H723
Example config updated to reflect this. This has been tested on the users board. To note, the H743
bin will flash to the H723 chip, but will not work.
