Subject: [RFC v4 2/3] arm64: boot: dts: qcom: sm8150: Enable dynamic TX FIFO resize logic
Date: Tue, 23 Jun 2020 19:28:47 -0700 [thread overview]
Message-ID: <20200624022848.7765-3-wcheng@codeaurora.org> (raw)
In-Reply-To: <20200624022848.7765-1-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.
