I verified that this matches what's in downstream.

I'm not able to test this yet since we're still on an old version of the
PCIe switch firmware and I need to get that upgraded first.

Note that your patch won't apply to linux-next since the v3 of my pcie3a
patch is what was actually merged into the qcom tree. Can you resend? You
can move the tlmm node to the bottom and add the PINCTRL comment.

I have some i2c and SPI changes that I'll be posting soon where I already
made that change but I'll hold off for you to post a new version and base
on top of yours.
