I2C controller ids are required when programming hardware blocks that send messages to devices connected to an I2C bus, such as when the PMC sends a poweroff message to the PMIC. Add ids to all I2C controllers in Tegra124. Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> --- arch/arm/boot/dts/tegra124.dtsi | 6 ++++++ 1 file changed, 6 insertions(+)
