PCI: Slot reset fixes

[PATCH 0/2] PCI: Slot reset fixes

Posted by Manivannan Sadhasivam 6 months, 4 weeks ago

Hi,

This series fixes the issues reported for the slot reset feature merged for
v6.16.

This series is on top of dw-rockchip branch where the slot reset patches are
merged. The patches in this series can be squashed into the respective commits
since they are not merged into mainline.

- Mani

Manivannan Sadhasivam (2):
  PCI: Save and restore root port config space in
    pcibios_reset_secondary_bus()
  PCI: Rename host_bridge::reset_slot() to
    host_bridge::reset_root_port()

Hey Mani,

I tested this series with the Rock5B RC <-> Rock5B EP. As expected, bus
resets now work as intended. Feel free to use:

Tested-by: Wilfred Mallawa <wilfred.mallawa@wdc.com>

Cheers,
Wilfred
