From 91352cfc7d2b1029a2659fadf69cf278aa2f1557 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 25 Jul 2012 14:02:44 -0600 Subject: [PATCH] ARM: dt: tegra trimslice: add vbus-gpio property commit 01ad8063a5db9ac8320f197577a34b423ba64eca upstream. On TrimSlice, Tegra's USB1 port may be routed to either an external micro USB port, or an internal USB->SATA bridge for SSD or HDD. This muxing is controlled by a GPIO. Whilst not strictly a VBUS GPIO, the TrimSlice board files caused this GPIO to be set appropriately to enable the SATA bridge by passing it as the VBUS GPIO to the USB driver. Echo this same configuration in device tree to enable the SATA bridge. An alternative might be to implement a full USB bus mux driver. However, that seems over-complex right now.
