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. Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Wesley Cheng <redacted>
Based on my previous request of always adding this for the Qualcomm platforms that supports it, which is implemented in patch 4, I don't see a need for this patch. Am I missing something? Regards, Bjorn
