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 to support 3rd controller witch HSIC

- on chip regulator 1P0D and HSIC_1P2 are enabled

- enable_usboh3_clk is called


any hints?
