The device-tree overlay for switching from Type-C USB interface to Type-A USB interface on J742S2-EVM and J784S4-EVM is also included in this series. Series is based on linux-next tagged next-20250226. v1 of this series is at: https://patchwork.kernel.org/project/linux-arm-kernel/cover/20250202093636.2699064-1-s-vadapalli@ti.com/ Changes since v1: - s/epf_bus/epf-bus in the first and second patch of this series since node names shouldn't contain underscores.
