Subject: [RESEND PATCH v17 13/17] leds: lp5523: Update the lp5523 code to add multicolor brightness function
Date: Mon, 27 Jan 2020 09:00:28 -0600 [thread overview]
Message-ID: <20200127150032.31350-14-dmurphy@ti.com> (raw)
In-Reply-To: <20200127150032.31350-1-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.
