Subject: [PATCH v5 0/10] A bunch of changes to refine i.MX PCIe driver
A bunch of changes to refine i.MX PCIe driver.
- Add ref clock gate for i.MX95 PCIe.
The changes of clock part are here [1], and had been applied by Abel.
[1] https://lkml.org/lkml/2024/10/15/390
- Clean i.MX PCIe driver by removing useless codes.
Patch #3 depends on dts changes. And the dts changes had been applied
by Shawn, there is no dependecy now.
- Make core reset and enable_ref_clk symmetric for i.MX PCIe driver.
- Use dwc common suspend resume method, and enable i.MX8MQ, i.MX8Q and
i.MX95 PCIe PM supports.
v5 changes:
Thanks for Manivannan's review.
- To avoid the DT compatibility on i.MX95, let to fetch i.MX95 PCIe clocks be
optinal in driver.
- Add Fixes tags into #5 and #6 patches.
- Split the clean up codes into #7.
- Update the commit message in #10, and #8
"PCI: imx6: Use dwc common suspend resume method" patches.
v4 changes:
It's my fault that I missing Manivannan in the reviewer list.
I'm sorry about that.
- Rebase to v6.12-rc3, and resolve the dtsi conflictions.
Add Manivannan into reviewer list.
v3 changes:
- Update EP binding refer to comments provided by Krzysztof Kozlowski.
Thanks.
v2 changes:
- Add the reasons why one more clock is added for i.MX95 PCIe in patch #1.
- Add the "Reviewed-by: Frank Li <Frank.Li@....com>" into patch #2, #4, #5,
#6, #8 and #9.
