Subject: [RFC v3 2/3] arm64: boot: dts: qcom: sm8150: Enable dynamic TX FIFO resize logic
Date: Wed, 27 May 2020 18:46:02 -0700 [thread overview]
Message-ID: <1590630363-3934-3-git-send-email-wcheng@codeaurora.org> (raw)
In-Reply-To: <1590630363-3934-1-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.
