Subject: [U-Boot] [PATCH v2 10/15] ARM: tegra: Workaround UDC boot issues only if necessary
Date: Tue, 19 Mar 2019 00:24:17 +0100	[thread overview]
Message-ID: <20190318232422.24404-11-thierry.reding@gmail.com> (raw)
In-Reply-To: <20190318232422.24404-1-thierry.reding@gmail.com>

From: Thierry Reding <treding@nvidia.com>

Resetting the USB device controller on boot is only necessary if the SoC
actually has a UDC controller and U-Boot enables support for it. All the
Tegra boards support UDC via the ChipIdea UDC driver, so make the UDC on
boot workaround depend on the ChipIdea UDC driver.

This prevents a crash on Tegra186 which does not have the ChipIdea UDC.
