Subject: [PATCH v20 14/17] leds: lp5521: Add multicolor framework multicolor brightness support
Date: Thu, 23 Apr 2020 10:55:21 -0500	[thread overview]
Message-ID: <20200423155524.13971-15-dmurphy@ti.com> (raw)
In-Reply-To: <20200423155524.13971-1-dmurphy@ti.com>

Add the multicolor brightness call back to support the multicolor
framework. This function allows setting the brightness across
grouped LED channels in a single call.
