Simon Guinot 525a588db4 drivers: led: add driver for PWM LEDs
This driver supports the PWM driven LEDs. The devices are created from
the DT nodes with a compatible property matching "pwm-leds". For each
child node a LED is created and its "pwms" phandle's node is used to
retrieve the PWM configuration: channel, period and flags. If some of
this properties are missing (it is the case for some PWM controllers),
then reasonable default values are used.

This driver implements the following LED API methods:

- led_on
- led_off
- led_blink
- led_set_brightness

Simon Guinot 21f4fef78b drivers: led: add shell support
This patch introduces the "led" shell command. This allows to run the
LED API functions (and to test the LED drivers) from the Zephyr shell.
The following subcommands are supported:

- on
- off
- get_info
- set_brightness
- set_color
- set_channel
- write_channels

Simon Guinot b37ea90335 drivers: led: add driver for TI LP503x controllers
This patch adds support for the Texas Instruments LP5030 and LP5036
I2C LED controllers. They are respectively providing up to 30 and 36
channels (i.e. 10 or 12 RGB LEDs).

In addition to the channel/color registers this LED controller provides
a per-LED brigthness register. This driver implements both LED-based and
channel-based API methods:

- led_on
- led_off
- led_get_info
- led_set_brightness
- led_set_color
- led_set_channel
- led_write_channels

Ulf Magnusson bd6e04411e 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*/# /'

Henrik Brix Andersen ac9356ade3 drivers: led: ht16k33: add LED driver for Holtek HT16K33 LED driver
The HT16K33 is a memory mapping, multifunction LED controller
driver. The controller supports up to 128 LEDs (up to 16 rows and 8
commons) and matrix key scan circuit of up to 13x3 keys.

This commit add support for the LED driver functionality of the
HT16K33.

Ulf Magnusson bfed59c1d4 drivers: led: Kconfig: Remove redundant 'default n' properties
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though, and is
inconsistent.

This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

Manivannan Sadhasivam 94bba071d6 drivers: led: Add public API for LED drivers
Add support for LED APIs for controlling the LED devices. This
API can be used by the LED devices present on the chip and connected
externally via buses like I2C, SPI etc...

Following APIs are currently supported:

1. led_blink
2. led_set_brightness
3. led_on
4. led_off

Driver support using these APIs will be added in subsequent patches.
