From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sergei Shtylyov Subject: [PATCH] ARM: shmobile: porter: add QSPI DT support Date: Fri, 09 Oct 2015 23:51:05 +0300 Message-ID: <1738678.v21ITp1gYW@wasted.cogentembedded.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7Bit Return-path: Sender: linux-sh-owner@vger.kernel.org To: horms@verge.net.au, linux-sh@vger.kernel.org, devicetree@vger.kernel.org, robh+dt@kernel.org, pawel.moll@arm.com, mark.rutland@arm.com, ijc+devicetree@hellion.org.uk, galak@codeaurora.org Cc: magnus.damm@gmail.com, linux@arm.linux.org.uk, linux-arm-kernel@lists.infradead.org List-Id: devicetree@vger.kernel.org Define the Porter board dependent part of the QSPI device node. Add device nodes for Spansion S25FL512S SPI flash and the MTD partitions on it. This patch is mostly analogous to the commit f59838d44835 (ARM: shmobile: henninger: add QSPI DT support) as there are no differences between the boards in this respect.
