Subject: [PATCH v6 4/4] arm64: boot: dts: qcom: sm8150: Enable dynamic TX FIFO resize logic
Date: Thu, 21 Jan 2021 20:01:40 -0800 [thread overview]
Message-ID: <1611288100-31118-5-git-send-email-wcheng@codeaurora.org> (raw)
In-Reply-To: <1611288100-31118-1-git-send-email-wcheng@codeaurora.org>
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.
