From mboxrd@z Thu Jan 1 00:00:00 1970 From: bhupesh.sharma@freescale.com (Bhupesh Sharma) Date: Fri, 4 Sep 2015 12:27:45 +0530 Subject: [PATCH v2 03/10] Documentation/dts: Add bindings for QIXIS FPGA controller found on FSL boards In-Reply-To: <1441349872-4560-1-git-send-email-bhupesh.sharma@freescale.com> References: <1441349872-4560-1-git-send-email-bhupesh.sharma@freescale.com> Message-ID: <1441349872-4560-4-git-send-email-bhupesh.sharma@freescale.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This patch adds bindings for QIXIS FPGA controller found on FSL boards. Some Freescale boards like LS2080AQDS/LS2080ARDB have an on-board FPGA/CPLD connected to the IFC controller. The bindings specified in this patch cater to those on-board FPGA/CPLD controllers.
