Subject: [PATCH v15 15/19] leds: lp5521: Add multicolor framework multicolor brightness support
Date: Mon, 28 Oct 2019 13:36:25 -0500 [thread overview]
Message-ID: <20191028183629.11779-16-dmurphy@ti.com> (raw)
In-Reply-To: <20191028183629.11779-1-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.
