Re-base to the pci-v6.1-changes of pci/next branch.
Update the cover-letter, and re-send the v12 patch-set.
This series adds the i.MX8MP PCIe support and tested on i.MX8MP
EVK board when one PCIe NVME device is used.
- i.MX8MP PCIe has reversed initial PERST bit value refer to i.MX8MQ/i.MX8MM.
Add the PHY PERST explicitly for i.MX8MP PCIe PHY.
- 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 v11-->v12:
- In the local down kernel(6.0-rc7 plus local codes) PM tests, i.MX8MP
PCIe encounters link failure.
To resolve this failure, the resets of i.MX8MP PCIe PHY should be always
kept 1b'1. Merge the fix into v12 patches here.
Main changes v10-->v11:
Refer to Ahmad's comments do the following changes;
- Correct the spell mistake and refine the commit log.
- Make codes indent by the member name
- Use the dev_err_probe replace the dev_err.
Main changes v9-->v10:
- Refer to Vinod's review comments, drop the array, and use the static data
structure directly in the drvdata definition.
Main changes v8-->v9:
- Split the PHY driver changes into three patches.
- To keep the format consistent, re-define the PHY_CMN_REG75, and remove
two useless BIT definitions.
- Refine the i.MX8MM PCIe PHY driver, let it more reviewable, flexible,
and easy to expand.
- Add the i.MX8MP PCIe PHY support.
- Only PHY related patches in v9, Since the others patches had been merged
by Phillipp/Shawn/Lorenzo [1].
Main changes v7-->v8:
- Add the Reviewed-by tag, no other changes.
Only two patches in v8, Since the others patches had been merged by
Phillipp/Shawn/Lorenzo [1].
