kconfig: Clean up header comments and make them consistent Use this short header style in all Kconfig files: # <description> # <copyright> # <license> ... Also change all <description>s from # Kconfig[.extension] - Foo-related options to just # Foo-related options It's clear enough that it's about Kconfig. The <description> cleanup was done with this command, along with some manual cleanup (big letter at the start, etc.) git ls-files '*Kconfig*' | \ xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /' Signed-off-by: Ulf Magnusson <Ulf.Magnusson@nordicsemi.no>

# Top-level configuration file for LED strip drivers.
drivers: led_strip: add public API for addressable LED strips This API covers drivers for strips, or strings, of individually addressable LEDs. Both RGB and grayscale LED strip drivers can be implemented within these APIs. The API only provides for updating the entire strip, since not all strips support updating individual LEDs without affecting the others. Subsequent patches will add individual driver support.

drivers: led_strip: Add driver for software-based WS2812B operation This driver uses a bit-banging based technique of generating a signal for the WS2812B LED strip. Since bit-banging is very timing sensitive, where each CPU cycle counts, the driver uses inline assembly to perform the most critical operataions. This initial version of the driver only supports a Cortex-M0 implementation, and can e.g. be used with the ZIP Halo LED strip for the BBC microbit: https://www.kitronik.co.uk/5625-zip-halo-for-the-bbc-microbit.html Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

kconfig: Global whitespace/consistency cleanup Clean up space errors and use a consistent style throughout the Kconfig files. This makes reading the Kconfig files more distraction-free, helps with grepping, and encourages the same style getting copied around everywhere (meaning another pass hopefully won't be needed). Go for the most common style: - Indent properties with a single tab, including for choices. Properties on choices work exactly the same syntactically as properties on symbols, so not sure how the no-indentation thing happened. - Indent help texts with a tab followed by two spaces - Put a space between 'config' and the symbol name, not a tab. This also helps when grepping for definitions. - Do '# A comment' instead of '#A comment' I tweaked Kconfiglib a bit to find most of the stuff. Some help texts were reflowed to 79 columns with 'gq' in Vim as well, though not all, because I was afraid I'd accidentally mess up formatting.

drivers: led_strip: add LPD880x driver LPD880x (e.g. LPD8803, LPD8806) devices are LED driver ICs which can be controlled via a reduced SPI interface (clock and data only), and support daisy chaining. Add an led_strip driver for these devices. Signed-off-by: Marti Bolivar <marti.bolivar@linaro.org>

drivers: led_strip: add WS2812-ish driver The WS2812 LED driver IC has a one-wire interface which encodes bit values as pulse widths. The ICs themselves are basically shift registers. Roughly speaking, a "short" pulse shifts in a zero bit, a "long" pulse shifts in a one bit, and an inter-pulse gap exceeding a reset time threshold causes a pixel to latch the shifted-in color values. Each chip has an output pin for daisy chaining. Refer to the chip datsheets and comments in Kconfig.ws2812 for more details. To meet timing without hogging the core, this driver generates pulses using SPI. To work, this requires the MOSI line to stay low between SPI frames, and for inter-frame delays to be less than the reset pulse time. There are other ways do it (PWM + DMA on some SoCs, GPIO bit-banging if no other tasks need the core), but this is a reasonably general-purpose implementation.
