Yes it depends it device support lpm or not.

We have the same problem with hw_port_is_high_speed [1]. Mapping is different

drivers/usb/chipidea/udc.c
static int hw_port_is_high_speed(struct ci13xxx *ci)
{
    return ci->hw_bank.lpm ? hw_read(ci, OP_DEVLC, DEVLC_PSPD) :
        hw_read(ci, OP_PORTSC, PORTSC_HSP);
}
