Thanx Tabi for your comments. Sorry I was on leave for the last week, so could not reply in time. Shall make the changes you suggested and repost the patch. Regards Poonam On 12/11/07, Timur Tabi [off-list ref] wrote:

If it is, then you need to take the QE's bus-frequency property and divide it by two. See my ucc_uart driver for an example. And PowerPC-specific patches should not be cross-posted to linux-kernel. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
