[PATCH v3 3/3] arm: mvebu: enable gpio expander over i2c on Mirabox platform
From: Gregory CLEMENT
Date: Tue Jan 22 2013 - 16:10:45 EST
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.
