Hi, In the m8xxhci.c hci driver for the mpc one can select to use TIMER1 for the SOF generator. A interruopt handler, m8xxhci_timer_interrupt() is registered to handle this interrupt and generate the SOF. Why is it then that the timer is also exported to PA6? Why is it the the USE_TIMER1_FOR_SOF is defined within the USE_UCODE_PATCH which is for external generated SOF-interrupt? Isn't the timer option exactly for the case where you do not have externally generated SOF-interrupt? If we can use a timer for generating the SOF why can't we just use a regular kernel timer instead, and therfore free one timer or baud rate generator?
Thanks, K.D. P.S. sorry for the x-post I am not shure if this belongs to the embedded list or the usb list. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
