Subject: [PATCH v29 14/16] leds: lp5521: Add multicolor framework multicolor brightness support
Date: Mon, 22 Jun 2020 13:59:17 -0500
Message-ID: <20200622185919.2131-15-dmurphy@ti.com> (raw)
In-Reply-To: <20200622185919.2131-1-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.
