Allow Arduino APIs to switch a pin between GPIO and peripheral functions by re-running the selected device init path when the requested owner changes. This is an interim pinmux handoff mechanism for boards where sketches may move a pin back and forth between serial/GPIO/PWM-style use.

Define `invalid_pin_number` and replace `pin_size_t(-1)`. Signed-off-by: TOKITA Hiroshi <tokita.hiroshi@gmail.com>
In preparation for improvements to allow the use of GPIOs without device tree definitions, the interface will be changed to specify port and pin instead of `gpio_dt_spec`. Signed-off-by: TOKITA Hiroshi <tokita.hiroshi@gmail.com>
Like digital pins, ADCs and PWMs are also defined from connectors. Signed-off-by: TOKITA Hiroshi <tokita.hiroshi@gmail.com>
Add guide for adding new board configuration and configuration reference. Signed-off-by: TOKITA Hiroshi <tokita.hiroshi@gmail.com>
A new configuration method has been adopted, allowing support to be added with less configuration than before. Signed-off-by: TOKITA Hiroshi <tokita.hiroshi@gmail.com>
Replace {0} with {} for port_callback, set dac_channel_cfg::internal
explicitly, and expand the adc_sequence initialization to make default
values explicit and avoid C++ initializer warnings.
