Modify Tegra30 default USB2 phy_type to UTMI; this matches power-on-reset defaults and is expected to be the common case. The current implementation is likely an incorrect carry-over from Tegra20, where USB2 does default to ULPI. Signed-off-by: Eric Brower <redacted> --- No upstream Tegra30 dts files reference USB2, so this should be a safe change; anyone using an out-of-tree dts with USB2, sparsely populated from the Tegra30 dtsi, may have an issue. v2: modified register base address for USB2 bias pad regs arch/arm/boot/dts/tegra30.dtsi | 21 ++++++++++++++++----- 1 file changed, 16 insertions(+), 5 deletions(-)
