Subject: [PATCH v2 1/2] ARM: DTS: tegra: Add USB entries for Tegra30
Date: Thu, 1 Aug 2013 18:00:17 +0300 [thread overview]
Message-ID: <1375369218-11288-2-git-send-email-ttynkkynen@nvidia.com> (raw)
In-Reply-To: <1375369218-11288-1-git-send-email-ttynkkynen@nvidia.com>
Add device tree entries for the 3 USB controllers and PHYs and
enable the third controller on Cardhu and Beaver boards.
Fix VBUS regulator entries on Beaver. The GPIO pins were wrong.
Also, internal pullups need to be enabled on those pins.
Signed-off-by: Tuomas Tynkkynen <ttynkkynen@nvidia.com>
---
v2: Use internal pullups on the VBUS regulator GPIOs.
