Date: Fri, 28 Aug 2020 22:58:42 -0700 From: Wesley Cheng <wcheng@...eaurora.org> To: robh+dt@...nel.org, bjorn.andersson@...aro.org, balbi@...nel.org, gregkh@...uxfoundation.org, agross@...nel.org Cc: linux-kernel@...r.kernel.org, linux-arm-msm@...r.kernel.org, devicetree@...r.kernel.org, linux-usb@...r.kernel.org, jackp@...eaurora.org, Wesley Cheng <wcheng@...eaurora.org> Subject: [RFC v5 2/6] arm64: boot: dts: qcom: sm8150: Enable dynamic TX FIFO resize logic Enable the flexible TX FIFO resize logic on SM8150. Using a larger TX FIFO SZ can help account for situations when system latency is greater than the USB bus transmission latency.
