doc/device-tree-bindings/leds/leds-bcm6328.txt can be found at
dts/upstream/Bindings/leds/leds-bcm6328.yaml.

doc/device-tree-bindings/leds/leds-bcm6358.txt can be found at
dts/upstream/Bindings/leds/leds-bcm6358.txt.

doc/device-tree-bindings/leds/leds-gpio.txt can be found at
dts/upstream/Bindings/leds/leds-gpio.yaml.

doc/device-tree-bindings/leds/leds-lp5562.txt can be found at
dts/upstream/Bindings/leds/leds-lp55xx.yaml.

Only two LED dt-bindings are left in U-Boot: leds-bcm6858.txt and
leds-pwm.txt. The former is partially supported by
dts/upstream/Bindings/leds/leds-bcm63138.yaml but is lacking all
optional properties we have listed in "downstream" dt-binding in U-Boot.
However, there doesn't seem to exist any user of that compatible.
The latter is partially supported by
dts/upstream/Bindings/leds/leds-pwm.yaml but is missing the
u-boot,default-brightness property, which is used by
arch/arm/dts/rk3326-odroid-go2-u-boot.dtsi at the moment. The
default-brightness property is probably not what we want here as it
defaults to max-brightness if missing. I'm assuming we want a different
value for U-Boot (127) and the kernel (255 via max-brightness as a
default), which would prevent us from upstreaming this property, which
doesn't change the status quo, so let it be for now.

<title>led: add TI LP5562 LED driver</title>

<id>f9dc67d18ee258d08fa620248d97e206b1cb849f</id>
<content type='text'>
Driver for the TI LP5562 4 channel LED controller. Supports
independent on/off control of all 4 channels. Supports LED_BLINK on 3
independent channels: blue/green/red. The white channel can blink, but
shares the blue channel blink rate.

Heavily based on patch originally from Doug Zobel [1].

I have modified it so it matches the DT bindings in the linux tree,
and also follows the linux driver implementation more closely. This
should address Tom's concerns, and also matches my goal of making the
U-Boot driver work with our existing .dts which is known to work in
linux.

As our boards only have the R,G,B outputs connected, I have not
actually tested how the white channel behaves, but the R,G,B work
exactly as expected.

Add a simple uclass for LEDs, so that these can be controlled by the device
tree and activated when needed. LEDs are referred to by their label.

This implementation requires a driver for each type of LED (e.g GPIO, I2C).
