The LTC3220/LTC3220-1 is a multi-display LED driver, which contains a
high-efficiency, low-noise charge pump to provide power to up to
18 LED current sources. The LEDs are individually configurable to
64-step linear brightness control, blinking and gradation control via
2-wire I2C interface. The blinking and gradation configuration is
shared across all LED.

LTC3220 has a quick write function which allows changing the
brightness on all LEDS simultaneously when the brightness is changed on

led 1.

For this we made quick write a device property which user can set on
the device tree. We would like to know if this approach is alright?
Another way we might want to know is, is it alright to just make a
virtual led for the quick write function. Changing brightness on the
virtual led will change the brightness for all.
