This can be flashed to e.g. the duet wifi using bossac. It requires a
later version as is currently included in the klipper repo (1.8
vs. 1.2). Comms are currently via UART0 only, USB serial is still TBD

Don't pass pin_type to lookup_pin() - instead, if a pin can be
inverted or can have a pullup, then the caller must explicitly specify
that when calling lookup_pin(). This simplifies the code for the
cases where it is not valid to invert or pullup.
Explicitly pass the pin_type to setup_pin() and have ppins.setup_pin()
apply default pullup and invert flags.

Add mcu support for periodically polling for a button press. Add host
code support for registering buttons and invoking callbacks for them.

Add a fully functional STM32F1 port, currently mostly targeting STM32F103
microcontrollers. This requires an 8 MHz XTAL. The maximum possible step rate
is around 282K steps per second.
This uses stm32flash to burn the firmware. The bootloader needs to be started
by setting BOOT0 to 1 and resetting the MCU. There is no automatic bootloader,
unlike on Arduino.

Most callers did a lookup of the pins module via
printer.lookup_object("pins"). Use that as the standard method and
remove these less frequently used methods.

Add get_reactor(), lookup_object(), lookup_module_objects(), and
set_rollover_info() to the main Printer class so that callers do not
need to peek into the class' members. Similarly, add get_printer()
and get_name() methods to the ConfigWrapper class.

Change the update_command() call to use a new PinResolver class. In
that new class, verify that the same pin isn't referenced in two
different parts of the config using different aliases for the pin.

It's common for multiple steppers to use the same stepper enable
line. Detect this and only create a single digital_out oid on the
micro-controller.
Also, prohibit any other pin from being used multiple times in the
config file.

Always set the pin_params['type'] field on a pin lookup. Rename
parse_pin_desc() to lookup_pin() to make the change more clear.

The atmega168 and atmega328 need to define PE0 and PE1 in order to
support the 2 extra analog pins.
Also, support the arduino mappings for the atmega328.

Add support for reading analog values via the standard Linux IIO
interface. This can be used on Replicape boards to sample analog
input pins.

It's no longer necessary to use the TICKS() hack as the config
commands are now all generated after the mcu speed is known.

Allow multiple chips to provide pin mappings (not just the main mcu
chip). Move the pin parsing from the mcu.py code to pins.py and
support mapping from pin descriptions to their corresponding chips and
parameters.

The atmega328 is basically the same as the atmega168 - it just adds
some additional memory. Allow the chip to be selected during the
build.

Introduce a TICKS() macro during config parsing that will translate
time in seconds to time in clock ticks.

Use map_pins() to obtain the pin mapping - don't export
mcu_to_pins(). The functionality of mcu_to_pins() can be obtained by
calling map_pins() with name=None.
