From mboxrd@z Thu Jan 1 00:00:00 1970 From: stephen.boyd@linaro.org (Stephen Boyd) Date: Sun, 26 Jun 2016 00:28:27 -0700 Subject: [PATCH 10/21] usb: chipidea: msm: Rely on core to override AHBBURST In-Reply-To: <20160626072838.28082-1-stephen.boyd@linaro.org> References: <20160626072838.28082-1-stephen.boyd@linaro.org> Message-ID: <20160626072838.28082-11-stephen.boyd@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The core framework already handles setting this parameter with a platform quirk. Add the appropriate flag so that we always set AHBBURST to 0. Technically DT should be doing this, but we always do it for msm chipidea devices so setting the flag in the driver works just as well.
