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>

drivers: led_strip: build as static library Instead of putting object files inside libzephyr.a, simply build a separate static library as most other driver types are doing this already. Signed-off-by: Daniel Leung <daniel.leung@intel.com>

drivers: led_strip: add WS2812 I2S-based driver Add a driver implementation that uses the I2S peripheral. Based off this blog post: https://electronut.in/nrf52-i2s-ws2812/ Should help with #33505, #29877 and maybe #47780, as there is no garbage data at the end of transmissions on nRF52832, and no gaps.

drivers: led_strip: add rpi_pico's PIO based ws2812 driver Add driver that based on RPI-PICO's PIO feature for ws2812. This driver can handle WS2812 or compatible LED strips. The single PIO node can handle up to 4 strips. Any pins that can be configured for PIO can be used for strips. I verified the samples/driver/led_ws2812 sample working with WS2812(144 pcs) led strip using following patches. - samples/drivers/led_ws2812/boards/rpi_pico.overlay ``` / { aliases { led-strip = &ws2812; }; }; &pinctrl { ws2812_pio0_default: ws2812_pio0_default { ws2812 { pinmux = <PIO0_P21>; }; }; }; &pio0 { status = "okay"; pio-ws2812 { compatible = "worldsemi,ws2812-rpi_pico-pio"; status = "okay"; pinctrl-0 = <&ws2812_pio0_default>; pinctrl-names = "default"; bit-waveform = <3>, <3>, <4>; ws2812: ws2812 { status = "okay"; output-pin = <21>; chain-length = <144>; color-mapping = <LED_COLOR_ID_GREEN LED_COLOR_ID_RED LED_COLOR_ID_BLUE>; reset-delay = <280>; frequency = <800000>; }; }; }; ``` - samples/drivers/led_ws2812/boards/rpi_pico.conf ``` CONFIG_WS2812_STRIP_RPI_PICO_PIO=y ``` Signed-off-by: TOKITA Hiroshi <tokita.hiroshi@gmail.com>
