Subject: [PATCH 15/16] bus: ti-sysc: Tag sdio and wdt with legacy mode for suspend
Date:   Mon, 23 Apr 2018 10:45:48 -0700
Message-Id: <20180423174549.57412-16-tony@atomide.com>
In-Reply-To: <20180423174549.57412-1-tony@atomide.com>
References: <20180423174549.57412-1-tony@atomide.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Looks like these two device drivers don't yet behave properly for suspend
unless configured with the legacy option.
