Hello, I try to use the third USB controller on a custom board. When writng the PORTSC register system stalls.
What we have done so far:
- use U-Boot rel_imx_4.1.15_1.2.0_ga
- extend ehci.mx to support 3rd controller witch HSIC
- on chip regulator 1P0D and HSIC_1P2 are enabled
- enable_usboh3_clk is called
