As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>. This patch proposes to then include <zephyr/kernel.h> instead of <zephyr/zephyr.h> since it is more clear that you are including the Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a catch-all header that may be confusing. Most applications need to include a bunch of other things to compile, e.g. driver headers or subsystem headers like BT, logging, etc. The idea of a catch-all header in Zephyr is probably not feasible anyway. Reason is that Zephyr is not a library, like it could be for example `libpython`. Zephyr provides many utilities nowadays: a kernel, drivers, subsystems, etc and things will likely grow. A catch-all header would be massive, difficult to keep up-to-date. It is also likely that an application will only build a small subset. Note that subsystem-level headers may use a catch-all approach to make things easier, though. NOTE: This patch is **NOT** removing the header, just removing its usage in-tree. I'd advocate for its deprecation (add a #warning on it), but I understand many people will have concerns. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no> |

.. _led_pwm: LED PWM sample application ########################## Overview ******** This sample allows to test the led-pwm driver. The first "pwm-leds" compatible device instance found in DT is used. For each LEDs attached to this device (child nodes) the same test pattern (described below) is executed. The LED API functions are used to control the LEDs. Test pattern ============ For each PWM LEDs (one after the other): - Turning on - Turning off - Increasing brightness gradually - Blinking on: 0.1 sec, off: 0.1 sec - Blinking on: 1 sec, off: 1 sec - Turning off Building and Running ******************** This sample can be built and executed on all the boards with PWM LEDs connected. The LEDs must be correctly described in the DTS: the compatible property of the device node must match "pwm-leds". And for each LED, a child node must be defined and the PWM configuration must be provided through a "pwms" phandle's node.
