From: David Brown Date: Fri, 7 Sep 2012 21:45:03 +0000 (-0700) Subject: msm_serial: fix clock rate on DMA-based uarts X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7b6031a7bcf3b191cf02caa2be6939df9266db40;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git msm_serial: fix clock rate on DMA-based uarts The driver explicitly requests a clock rate for the UART, but it is off by a factor of four from the dividers that it programs into the UART. Fix this by setting the rate to 1/4 of the current value.
