Subject: [PATCH v8 5/5] arm64: boot: dts: qcom: sm8150: Enable dynamic TX FIFO resize logic
Date: Wed, 19 May 2021 00:43:58 -0700	[thread overview]
Message-ID: <1621410238-31395-6-git-send-email-wcheng@codeaurora.org> (raw)
In-Reply-To: <1621410238-31395-1-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.
