The patch titled atmel_serial: filter out FP during baud rate detection has been removed from the -mm tree. Its filename was atmel_serial-filter-out-fp-during-baud-rate-detection.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: atmel_serial: filter out FP during baud rate detection From: Haavard Skinnemoen <haavard.skinnemoen@xxxxxxxxx> I made a change to u-boot that used the FP (Fractional Part) field of BRGR to achieve more accurate baud rate generation. Unfortunately, the atmel_serial driver looks at the whole BRGR register when trying to detect the baud rate that the port is currently running at, so setting FP to a nonzero value breaks the baud rate detection. I'll sit on the u-boot patch for a while longer, but this is clearly a bug in the atmel_serial driver which should be fixed.
