Subject: [PATCH 3/3] arm: mvebu: enable gpio expander over i2c on Mirabox platform
Date: Sun, 6 Jan 2013 18:34:48 +0100 [thread overview]
Message-ID: <1357493688-25061-4-git-send-email-gregory.clement@free-electrons.com> (raw)
In-Reply-To: <1357493688-25061-1-git-send-email-gregory.clement@free-electrons.com>
The Globalscale Mirabox platform can be connected to the JTAG/GPIO box
through the Multi-IO port. The GPIO box use the NXP PCA9505 I/O port
expansion IC to provide 40-bit parallel input/output GPIOs. This patch
enable the use of this expander on the Mirabox.
