Subject: [PATCH v3 02/10] arm: dt: Tegra20: Modify ULPI reset GPIO properties
Date: Fri, 10 May 2013 19:24:03 +0530 [thread overview]
Message-ID: <1368194051-4925-3-git-send-email-vbyravarasu@nvidia.com> (raw)
In-Reply-To: <1368194051-4925-1-git-send-email-vbyravarasu@nvidia.com>
changes with this patch:
1. All Tegra20 ULPI reset GPIO DT properties are modified to indicate active
low nature of the GPIO.
2. Placed USB PHY DT node immediately below the EHCI controller DT nodes
and corrected reg value in the name of USB PHY DT node.
