Hi All,
This patch series adds support for endpoint driver for R-Car PCIe controller on
R-Car/RZ-G2x SoC's, this also extends the epf framework to handle multiple windows
supported by the controller for mapping PCI address locally.
Note:
The cadence/rockchip/designware endpoint drivers are build tested only.
Changes for v9 (Re-spun this series as there were minimal changes requested):
* Rebased patches on top of v5.7.rc1
* Replaced mdelay(1) with usleep_range(1000, 1001) in rcar_pcie_ep_assert_intx()
* Added a check for max_functions read from DT to restrict with
RCAR_EPC_MAX_FUNCTIONS
* Replaced MSICAP0_MMENUM with MSICAP0_MMESE
* Retry ioremap for other windows on failure in pci_epc_mem_alloc_addr()
* Fixed looping for number windows in pci_epc_mem_exit()
* Set maximum to 1 for max-functions in DT binding (I have restored the acks
from Rob and Shimoda-san)
* Sorted the entry in MAINTAINERS
Changes for v8:
* Dropped adding R8A774C0 (0x002d) pci-id in pci_ids.h
* Fixed typo in commit message for patch 2/8
* Reworded commit message for patch 5/8 as suggested by Bjorn
* Split up patch to add pci_epc_mem_init() interface to add page_size argument
as suggested by Bjorn.
Changes for v7:
* Fixed review comments pointed by Shimoda-san
1] Made DT bindings dual licensed, added Shimoda-san as maintainer and fixed
the example as its built with #{address,size}-cells = <1>. I have still
restored the Ack from Rob and Shimoda-san with these changes.
2] Split up the patches so that they can be picked up by respective subsystem
patches 1/4-9/11 are now part of this series.
3] Dropped altering a comment in pci-epc.h
4] Used a local variable align_size in pci_epc_mem_alloc_addr() so that size
variable doesn't get overwritten in the loop.
5] Replaced i-=1 with i--
6] Replaced rcar with R-Car in patch subject and description.
7] Set MACCTLR in init() callback
Changes for v6:
1] Rebased patches on endpoint branch of https://git.kernel.org/pub/
scm/linux/kernel/git/lpieralisi/pci.git/
2] Fixed review comments from Shimoda-san
a] Made sure defconfig changes were in separate patch
b] Created rcar_pcie_host/rcar_pcie_ep structures
c] Added pci-id for R8A774C0
d] Added entry in MAINTAINERS for dt-binding
e] Dropped unnecessary braces
3] Added support for msi.
Changes for v5:
1] Rebased patches on next branch of https://git.kernel.org/pub/scm/
linux/kernel/git/helgaas/pci.git
2] Fixed review comments reported by Kishon while fetching the matching
window in function pci_epc_get_matching_window()
3] Fixed review comments reported by Bjorn
a] Split patch up first patch so that its easier to review and incremental
b] Fixed typos
4] Included Reviewed tag from Rob for the dt-binding patch
5] Fixed issue reported by Nathan for assigning variable to itself
Changes for v4:
1] Fixed dtb_check error reported by Rob
2] Fixed review comments reported by Kishon
a] Dropped pci_epc_find_best_fit_window()
b] Fixed initializing mem ptr in __pci_epc_mem_init()
c] Dropped map_size from pci_epc_mem_window structure
Changes for v3:
1] Fixed review comments from Bjorn and Kishon.
3] Converted to DT schema
Changes for v2:
1] Fixed review comments from Biju for dt-bindings to include an example
for a tested platform.
2] Fixed review comments from Kishon to extend the features of outbound
regions in epf framework.
3] Added support to parse outbound-ranges in OF.
