Subject[PATCH v2 0/7] Add the iMX8MP PCIe support
Date
Based on the i.MX8MP GPC and blk-ctrl patch-set[1] issued by Lucas and the
following commits.
- one codes refine patch-set[5].
- two Fixes[2],[3].
- one binding commit[4].
- some dts changes in Shawn's git if you want to test PCIe on i.MX8MM EVK.
b4d36c10bf17 arm64: dts: imx8mm-evk: Add the pcie support on imx8mm evk board
aaeba6a8e226 arm64: dts: imx8mm: Add the pcie support
cfc5078432ca arm64: dts: imx8mm: Add the pcie phy support

Sorry about that there may be some conflictions when do the codes merge.
I'm waiting for the ack now, and will re-base them in a proper sequence later.

This series patches add the i.MX8MP PCIe support and tested on i.MX8MM EVK and
i.MX8MP EVk boards. The PCIe NVME works fine on both boards.

- i.MX8MP PCIe PHY has two resets refer to the i.MX8MM PCIe PHY.
Add one more PHY reset for i.MX8MP PCIe PHY accordingly.
- Add the i.MX8MP PCIe PHY support in the i.MX8M PCIe PHY driver.
And share as much as possible codes with i.MX8MM PCIe PHY.
- Add the i.MX8MP PCIe support in binding document, DTS files, and PCIe
driver.

Main changes v1-->v2:
- It's my fault forget including Vinod, re-send v2 after include Vinod
and linux-phy@lists.infradead.org.
- List the basements of this patch-set. The branch, codes changes and so on.
- Clean up some useless register and bit definitions in #3 patch.
