license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>

samples: various servo_motor fixes Though there were issues with this sample before e959386bd2 ("samples: servo_motor: cleanups and changes"), that commit introduced further bugs. This happened because the new pwm-servo alias that commit switched to wasn't provided by any boards, so it wasn't built in CI. Before that, however, the recommendation to use bbc_microbit in the sample documentation was also buggy in a couple of ways: 1. bbc_microbit doesn't have the pwm-0 alias the sample previously required, so it didn't build on that board 2. the documentation's comment to use pin 0 on the edge connector is wrong; PWM channel 0 is wired to GPIO P0.0 on the SoC, which is actually pin 21 on the connector Fix it all up. Tested on bbc_microbit. I verified the pinout and also made sure that the sample correctly generates pulses from 700 to 2300 usec. Signed-off-by: Martí Bolívar <marti.bolivar@nordicsemi.no>

samples: basic: servo_motor: use pwm_dt_spec The sample did not use PWM in a proper way: it relied on a PWM device handle, but channel or flags were hardcoded in the code. This patch changes the sample to use a local binding ("pwm-servo") where the `pwms` property is defined. This allows to make use of pwm_dt_spec facilities, reducing the overall sample complexity and making it more portable without editing the source code. The custom binding also requires to provide the minimum/maximum pulse width so that different servos can be easily plugged in without the need to edit sources.
