2020-01-13PCI: exynos: Rename Exynos to lowercaseKrzysztof Kozlowski
Fix up inconsistent usage of upper and lowercase letters in "Exynos" name. "EXYNOS" is not an abbreviation but a regular trademarked name. Therefore it should be written with lowercase letters starting with capital letter. The lowercase "Exynos" name is promoted by its manufacturer Samsung Electronics Co., Ltd., in advertisement materials and on website.

2019-09-04PCI: exynos: Propagate errors for optional PHYsThierry Reding
devm_of_phy_get() 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 devres structures. Propagating only -EPROBE_DEFER is problematic because it results in these legitimately fatal errors being treated as "PHY not specified in DT". What we really want is to ignore the optional PHYs only if they have not been specified in DT. devm_of_phy_get() 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.

2018-07-13PCI: exynos: Drop unnecessary root_bus_nr settingShawn Guo
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. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Cc: Jingoo Han <jingoohan1@gmail.com>
2018-06-08PCI: Collect all native drivers under drivers/pci/controller/Shawn Lin
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.
