From 8034891b81f0f7285c1efa3ae29e46b3f177536e Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Thu, 16 May 2013 18:07:24 +0200 Subject: arm: mvebu: enable the third USB interface on OpenBlocks AX3 Besides the two "classic" USB interfaces with normal USB ports on the front side, the PlatHome OpenBlocks AX3 uses the third USB interface of the Marvell SoC in the mini-PCIe connector. This allows certain mini-PCIe cards to expose parts of their functionality as a USB peripheral. This commit enables this third USB interface in the OpenBlocks AX3 Device Tree, and also adds comments on top of the two other USB interfaces so that the Device Tree makes it clear which USB interface at the SoC level matches which USB interface visible on the board.
