Looks like the those pin enable as GPIO pin.
Did you using r32.6.1? This version should have problem or didn’t you add those pin under the gpio@6000d000? Remove the TEGRA_GPIO B an B to try
gpio: gpio@6000d000 {
gpio-init-names = "default";
gpio-init-0 = <&gpio_default>;
gpio_default: default {
gpio-input = <
