Subject: [PATCH v28 12/15] leds: lp5523: Update the lp5523 code to add multicolor brightness function
Date: Wed, 17 Jun 2020 10:09:21 -0500 [thread overview]
Message-ID: <20200617150924.12665-13-dmurphy@ti.com> (raw)
In-Reply-To: <20200617150924.12665-1-dmurphy@ti.com>
Add the multicolor brightness call back to support the multicolor
framework. This call back allows setting brightness on grouped channels
in a single function.
