From mboxrd@z Thu Jan 1 00:00:00 1970 From: davidb@codeaurora.org (David Brown) Date: Wed, 2 Nov 2011 11:36:31 -0700 Subject: [RFC PATCH 34/34] msm_serial: fix clock rate on DMA-based uarts In-Reply-To: <1320258991-22325-1-git-send-email-davidb@codeaurora.org> References: <1320258991-22325-1-git-send-email-davidb@codeaurora.org> Message-ID: <1320258991-22325-35-git-send-email-davidb@codeaurora.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
