[PATCH v6 4/4] arm64: boot: dts: qcom: sm8150: Enable dynamic TX FIFO resize logic

From: Wesley Cheng <hidden>
Date: 2021-01-22 04:03:07
Also in: linux-arm-msm, linux-devicetree, lkml
Subsystem: arm/qualcomm mailing list, arm/qualcomm support, the rest · Maintainers: Bjorn Andersson, Konrad Dybcio, Linus Torvalds

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.
