Subject: [PATCH/RFT v2 02/17] ARM: davinci: da8xx: Add CFGCHIP syscon platform declaration.
Date: Mon, 24 Oct 2016 18:46:19 +0200 [thread overview]
Message-ID: <20161024164634.4330-3-ahaslam@baylibre.com> (raw)
In-Reply-To: <20161024164634.4330-1-ahaslam@baylibre.com>
From: David Lechner <david@lechnology.com>
The CFGCHIP registers are used by a number of devices, so using a syscon
device to share them. The first consumer of this will by the phy-da8xx-usb
driver.
