It is not present in spi3 bus pins. Is it a chip select pin? If you remove the default configuration, it will still work as input-pull down because no one is setting different config. Why you need to touch gpg3-5? Best regards, Krzysztof

Add the device tree node for the ir-spi driver which enable the ir led for remote controlling. This patch sets first the GPR3[3] gpio line as a regulator-fixed for enabling an external regulator which powers the IR LED. Removes also the default assignment of the GPG3[5] and GPG3[7] related to the SPI3 line.
