2019-10-15	PCI: endpoint: Cast the page number to phys_addr_t	Alan Mikhak	1	-1/+1
	Modify pci_epc_mem_alloc_addr() to cast the variable 'pageno' from type 'int' to 'phys_addr_t' before shifting left. This cast is needed to avoid treating bit 31 of 'pageno' as the sign bit which would otherwise get sign-extended to produce a negative value. When added to the base address of PCI memory space, the negative value would produce an invalid physical address which falls before the start of the PCI memory space.

2018-01-28	PCI: Add SPDX GPL-2.0 to replace GPL v2 boilerplate	Bjorn Helgaas	1	-12/+1
	Add SPDX GPL-2.0 to all PCI files that specified the GPL version 2 license. Remove the boilerplate GPL version 2 language, relying on the assertion in b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") that the SPDX identifier may be used instead of the full boilerplate text.

2017-08-29	PCI: endpoint: Add support for configurable page size	Kishon Vijay Abraham I	1	-9/+50
	pci-epc-mem uses a page size equal to PAGE_SIZE (usually 4KB) to manage the address space. However certain platforms like TI's K2G have a restriction that this address space should be either divided into 1MB/2MB/4MB or 8MB sizes (Ref: 11.14.4.9.1 Outbound Address Translation in K2G TRM SPRUHY8F January 2016 – Revised May 2017). Add support to handle different page sizes here. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2017-04-11	PCI: endpoint: Add EP core layer to enable EP controller and EP functions	Kishon Vijay Abraham I	1	-0/+143
	Introduce a new EP core layer in order to support endpoint functions in linux kernel. This comprises the EPC library (Endpoint Controller Library) and EPF library (Endpoint Function Library). EPC library implements functions specific to an endpoint controller and EPF library implements functions specific to an endpoint function.
