From 4f532403b1e5b379e4027448da715567a2b3ff57 Mon Sep 17 00:00:00 2001 From: Fabrice Gasnier Date: Fri, 14 Oct 2022 16:15:08 +0200 Subject: [PATCH] ARM: dts: stm32: enable USB OTG in dual role mode on stm32mp135f-dk The USB OTG controller provides the USB data available on stm32mp135f-dk, on the Type-C connector. Data role is determined by "usb-role-switch". A STM32G0 provides the USB Type-C and Power Delivery connectivity. It controls dual role power and dual role data through UCSI protocol over I2C. It's wired on I2C1, with an interrupt pin on PI2 GPIO. Its firmware maybe updated over I2C, so use the optional firmware-name to enable firmware update.
