Subject: [PATCH v12 13/16] leds: lp5523: Update the lp5523 code to add intensity function
Date: Fri, 11 Oct 2019 08:06:54 -0500 [thread overview]
Message-ID: <20191011130657.4713-14-dmurphy@ti.com> (raw)
In-Reply-To: <20191011130657.4713-1-dmurphy@ti.com>
Add the intensity function call back to support the multicolor
framework. This function allows setting a specific brightness on
a specific channel.
