Some SoC/IP as STM32F469, the snpsid can only be read after clock is enabled, otherwise it will read as 0, and the dwc2_check_core_endianness will assume the core and AHB have opposite endianness, leading to the following error: [ 1.976339] dwc2 50000000.usb: 50000000.usb supply vusb_d not found, using dummy regulator [ 1.986124] dwc2 50000000.usb: Linked as a consumer to regulator.0 [ 1.992711] dwc2 50000000.usb: 50000000.usb supply vusb_a not found, using dummy regulator [ 2.003672] dwc2 50000000.usb: dwc2_core_reset: HANG! AHB Idle timeout GRSTCTL GRSTCTL_AHBIDLE [ 2.015176] dwc2: probe of 50000000.usb failed with error -16 The proposed patch changes the location where dwc2_check_core_endianness is called, allowing the clock peripheral to be enabled first.
