AM37xx : after global resume the ohci port disconnect

Other Parts Discussed in Thread: AM3715, SYSCONFIG

Hi,

I am using AM3715 in our platform and the kernel is from TI_Android_GingerBread_2_3_4Sources.

A full speed usb transceiver is connected with 4-pin phy mode, and follows up a GSM module(CINTERION product : PH8)

 

I have notice that TI didn't support ohci suspend/resume function in ohci_omap3.c

So, i add suspend/resume to support global suspend.

(Writing OMAP_USBTLL_SYSCONFIG & OMAP_UHH_SYSCONFIG register value and disable some clocks)

 

But when system try to resume usb port, usb port resume is not work because the port status of port 3 is not connect?

Any suggestion?

P.S. Does TI will release 'formal' suspend/resume function for ohci driver for GingerBread?
