From 66bcb58ba430034e7d58a37bf4f7c6904d6442cf Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Tue, 22 Jan 2013 22:10:25 +0100 Subject: arm: mvebu: enable gpio expander over i2c on Mirabox platform 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.
