Update the device tree to indicate which I2C controller is the DVC controller. AUXDATA needs to be updated too, since the compatible value changed. Signed-off-by: Stephen Warren <redacted> --- It'd be best to apply this to the same tree as the previous patch. If that doesn't happen, the DVC I2C driver won't be instantiated due to the compatible value not being supported. In practice, this isn't an issue though, since nothing uses the DVC I2C controller yet. This relies on 0d4f747 "arm/tegra: convert tegra20 to GIC devicetree binding" for context. arch/arm/boot/dts/tegra20.dtsi | 2 +- arch/arm/mach-tegra/board-dt.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-)
