2018-10-20	PCI: dwc: Fix scheduling while atomic issues	Jisheng Zhang
	[ Upstream commit 9024143e700f89d74b8cdaf316a3499d74fc56fe ] When programming the inbound/outbound ATUs, we call usleep_range() after each checking PCIE_ATU_ENABLE bit. Unfortunately, the ATU programming can be executed in atomic context: inbound ATU programming could be called through pci_epc_write_header() =>dw_pcie_ep_write_header() =>dw_pcie_prog_inbound_atu() outbound ATU programming could be called through pci_bus_read_config_dword() =>dw_pcie_rd_conf() =>dw_pcie_prog_outbound_atu() Fix this issue by calling mdelay() instead. Fixes: f8aed6ec624f ("PCI: dwc: designware: Add EP mode support") Fixes: d8bbeb39fbf3 ("PCI: designware: Wait for iATU enable") Signed-off-by: Jisheng Zhang <Jisheng.Zhang@synaptics.com> [lorenzo.pieralisi@arm.com: commit log update] Signed-off-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Gustavo Pimentel <gustavo.pimentel@synopsys.com> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-06-08	PCI: 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.
