- Enable starfive controller runtime PM before probing host bridge (Mayank
Rana)
- Enable runtime power management for host bridges (Krishna chaitanya
chundru)
* pci/pm:
PCI: Enable runtime PM of the host bridge
PCI: starfive: Enable controller runtime PM before probing host bridge
|
|
A PCI controller device, e.g., StarFive, is parent to PCI host bridge
device. We must enable runtime PM of the controller before enabling runtime
PM of the host bridge, which will happen in pci_host_probe(), to avoid this
warning:
pcie-starfive 940000000.pcie: Enabling runtime PM for inactive device with active children
Fix this issue by enabling StarFive controller device's runtime PM before
calling pci_host_probe() in plda_pcie_host_init().

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return
void") .remove() is (again) the right callback to implement for platform
drivers.
Convert all PCI controller drivers to use .remove(), with the eventual goal
to drop struct platform_driver::remove_new(). As .remove() and .remove_new()
have the same prototypes, conversion is done by just changing the structure
member name in the driver initializer.
