Move the IS_ENABLED(CONFIG_PCI_MSI) check into dw_pcie_msi_init()
instead of duplicating it in all the drivers.

Now that DWC drivers can setup their own pci_ops for the root and child
buses, convert the HiSilicon histb driver to use the standard pci_ops
for root bus config accesses.

- Remove redundant logging for platform_get_irq() errors (Krzysztof
Wilczyński)
* pci/irq-error:
PCI: Remove dev_err() when handing an error from platform_get_irq()
|
|
There is no need to call the dev_err() function directly to print a
custom message when handling an error from either the platform_get_irq() or
platform_get_irq_byname() functions as both are going to display an
appropriate error message in case of a failure.
This change is as per suggestions from Coccinelle, e.g.,
drivers/pci/controller/dwc/pcie-armada8k.c:252:2-9: line 252 is
redundant because platform_get_irq() already prints an error

Use devm_platform_ioremap_resource_byname() to simplify the code
since it contains platform_get_resource_byname() and
devm_ioremap_resource() respectively.

regulator_get_optional() can fail for a number of reasons besides probe
deferral. It can for example return -ENOMEM if it runs out of memory as
it tries to allocate data structures. Propagating only -EPROBE_DEFER is
problematic because it results in these legitimately fatal errors being
treated as "regulator not specified in DT".
What we really want is to ignore the optional regulators only if they
have not been specified in DT. regulator_get_optional() returns -ENODEV
in this case, so that's the special case that we need to handle. So we
propagate all errors, except -ENODEV, so that real failures will still
cause the driver to fail probe.

The dw_pcie_host_ops structure is only stored in the ops field
of a pcie_port structure, and this field is const, so make the
dw_pcie_host_ops structure const as well.
Done with the help of Coccinelle.

Function dw_pcie_host_init() already initializes the root_bus_nr field
of 'struct pcie_port', so the -1 assignment prior to calling
dw_pcie_host_init() in platform specific driver is not really needed.
Drop it.

Native PCI drivers for root complex devices were originally all in
drivers/pci/host/. Some of these devices can also be operated in endpoint
mode. Drivers for endpoint mode didn't seem to fit in the "host"
directory, so we put both the root complex and endpoint drivers in
per-device directories, e.g., drivers/pci/dwc/, drivers/pci/cadence/, etc.
These per-device directories contain trivial Kconfig and Makefiles and
clutter drivers/pci/. Make a new drivers/pci/controllers/ directory and
collect all the device-specific drivers there.
No functional change intended.
