pci: rockchip: Release resources on failing probe

2023-08-12T01:59:18Z

The PCIe driver for RK3399 is affected by a similar issue that was fixed for RK35xx in the commit e04b67a7f4c1 ("pci: pcie_dw_rockchip: release resources on failing probe"). Resources are not released on failing probe, e.g. regulators may be left enabled and the ep-gpio may be left in a requested state. Change to use regulator_set_enable_if_allowed and disable regulators after failure to keep regulator enable count balanced, ep-gpio is also released on regulator failure. Also add support for the vpcie12v-supply, remove unused include and check return value from dev_read_addr_name. Signed-off-by: Jonas Karlman Reviewed-by: Kever Yang

pci: pcie_dw_rockchip: Disable unused BARs of the root complex

The Root Complex BARs default to claim the full 1 GiB memory region on RK3568, leaving no space for any attached device. Fix this by disable the unused BAR 0 and BAR 1 of the RC.

pci: pcie_dw_rockchip: Speed up link probe

2023-07-28T10:45:03Z

Use a similar pattern and delay values as the linux mainline driver to speed up failing when nothing is connected. Reduce fail speed from around 5+ seconds down to around one second on a Radxa ROCK 3 Model A, where pcie2x1 is probed before pcie3x2 M2 slot. Signed-off-by: Jonas Karlman Reviewed-by: Kever Yang

pci: pcie_dw_rockchip: Use regulator_set_enable_if_allowed

2023-07-28T10:45:03Z

The vpcie3v3 regulator is typically a fixed regulator controlled using gpio. Change to use enable and disable calls on the regulator instead of trying to set a voltage value. Also remove the delay to match linux driver, for a fixed regulator the startup-delay-us prop can be used in case a startup delay is needed. Limited testing on ROCK 3A, ROCK 5B, Quartz64, Odroid-M1 has shown that this delay was not needed. Signed-off-by: Jonas Karlman Reviewed-by: Kever Yang
