Unfortunately currently both Apalis T30 as well as Colibri T30 crash upon starting USB host support. This is due to the following patch not having taken into account that our T30 device trees were defaulting to peripheral only mode instead of otg:
commit ddb9a502d18008e845d5a8fa03ec48630fa77fb7 dm: usb: tegra: Move most of init/uninit into a function
This patch fixes this by defaulting to otg now.
