[PATCH v8 5/5] arm64: boot: dts: qcom: sm8150: Enable dynamic TX FIFO resize logic

From: Wesley Cheng
Date: Wed May 19 2021 - 03:44:26 EST


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.
