Subject: [PATCH v5 0/2] Add new UniPhier PCIe host driver
Date: Fri, 7 Dec 2018 09:53:10 +0900 [thread overview]
Message-ID: <1544143992-16385-1-git-send-email-hayashi.kunihiko@socionext.com> (raw)
This series adds PCIe host controller driver for Socionext UniPhier SoCs.
This controller is based on the DesignWare PCIe core. This driver
supports LD20 and PXs3 SoCs.
v4: https://www.spinics.net/lists/linux-pci/msg78278.html
About legacy IRQ, it might be necessary to share common view from
keystone driver that have been cleaned up[1].
[1] https://lore.kernel.org/patchwork/patch/989541/
Changes since v4:
- fix an issue of using the wrong value to mask IRQ mask register
Changes since v3:
- dt-bindings: fix INTX numbering of legacy interrupt map
- change interrupts to level ones
- remove .xlate function
- merge uniphier_pcie_ltssm_disable() into uniphier_pcie_ltssm_enable()
- remove an error message on uniphier_pcie_establish_link()
- change the order between irq_domain_add_liniear() and
irq_set_chained_handler_and_data()
- replace dummy_irq_chip with uniphier_pcie_irq_chip and its functions
- add dependency on CONFIG_HAS_IOMEM
- MAINTAINERS: add pcie-uniphier entry
Changes since v2:
- dt-bindings: remove a comment that the node name isn't important
- dt-bindings: remove "intx" interrupt
- dt-bindings: define 'legacy-interrupt-controller' node and its properties
- return an error value when link up fails
- remove devm_request_irq() and a handler for MSI IRQ
- use chained interrupt instead of devm_request_irq() for legacy IRQ
- add unipher_pcie_config_legacy_irq() to get legacy IRQ from
'legacy-interrupt controller' node
- replace 4 statments to handle INTX with for_each_set_bit()
- remove initialization of pp->root_bus_nr
- remove indivisual interrupt enable bit definitions
- rename 'irq_domain' member to 'legacy_irq_domain' in private structure
- use pci_irqd_intx_xlate() for irq_domain_ops.xlate function
Changes since v1:
- follow capitalization conventions in the descriptions
- use C style comments except for the SPDX line
