Subject: [PATCH v1 04/16] mfd: mt6397: add MT6323 RTC support into MT6397 driver
Date: Fri, 23 Mar 2018 17:15:01 +0800	[thread overview]
Message-ID: <90320622cb491b9d3251e2ce9d0501422f47660f.1521794177.git.sean.wang@mediatek.com> (raw)
In-Reply-To: <cover.1521794176.git.sean.wang@mediatek.com>

From: Sean Wang <sean.wang@mediatek.com>

Add compatible string as "mt6323-rtc" that will make the OF core spawn
child devices for the RTC subnode of that MT6323 MFD node.
