Thanks and regards, Lokesh I've ported the two patches on the top of clk data branch to both of linux-omap tree and Linus's kernel. They all work now. Thanks a lot. And a few more questions, ;-) I read the timer initialization codes in kernel. It looks like the Linux kernel does not use the architected timer of Cortex-A15 MPCore. I tried to use arch_timer_get_cntfrq() to get its rate, but failed(returned frequency is 0). I'm wondering if it is because of lack of initialization or other issues. Another question is about UART on OMAP5432. This is origin from my attempt to porting Xen to OMAP5432. Now Xen has already had a 8250 compatible driver. What I have done is to hook it with Xen's arm initialization codes (for example, hook it with device tree). Xen's original driver is rather simple compared to the Linux omap-serial.c. It enables receive and transmit interrupts in the end of initialization. Once the interrupt is enabled, it would generate nested interrupt of THRE and make the system dead loop in the interrupt handler. I have been digging this problem for nearly a month and haven't got a clue yet. I guess it might be caused by uninitialized architected timer, which then lead me to the previous question. Any idea?

Tero's approach is what is being massaged for upstream as we do not wish to add additional clock data into kernel source tree anymore. -- Regards, Nishanth Menon -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
