Subject: [PATCH v3 10/16] ARM: davinci: da8xx: Add CFGCHIPn syscon platform declaration.
Date: Thu, 24 Mar 2016 18:51:35 -0500 [thread overview]
Message-ID: <1458863503-31121-11-git-send-email-david@lechnology.com> (raw)
In-Reply-To: <1458863503-31121-1-git-send-email-david@lechnology.com>
The CFGCHIPn 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.
Signed-off-by: David Lechner <david@lechnology.com>

v3 changes: This is a new patch. There is one syscon device for all CFGCHIP
registers.
