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?
Looks like Wesley had quickly sent a V9 of the series right after V8, and the DTSI change is dropped. https://lore.kernel.org/linux-usb/1621410561-32762-1-git-send-email-wcheng@codeaurora.org/T/#t (local) Thanks, Jack
