On our board we have a GPIO I2C multiplexer. We have used this chip with the TX1 module attached to our board but when we attempt to use it with the TX2 we have observed an issue.
In order to use this multiplexer I configure two pins to be an output. I looked up the port and offset for this particular pin (G7) within the Pinmux Spreadsheet, this yields Port ‘V’ offset 5
Within my dts file I use the macro TEGRA_MAIN_GPIO(PORT, OFFSET) to get the correct address.
I’ve verified this works with other GPIOs but when I try and compile the kernel with
I get this error:
Error: /home/cospan/Projects/nvidia_3.0/Linux_for_Tegra/sources/kernel/kernel-4.4/../../hardware/nvidia/platform/t18x/common/kernel-dts/t18x-common-modules/tegra186-camera-mit-uav-revb.dtsi:40.2-9 syntax error FATAL ERROR: Unable to parse input tree
If I temporarily change the GPIO to a free GPIO things build just fine but I need this pin.
Is there something I’m doing wrong?
Thanks for any help,
