2016-10-11PCI: hisi: Remove redundant struct hisi_pcie.reg_baseBjorn Helgaas
Remove the struct hisi_pcie.reg_base member, which is a duplicate of the generic pp.dbi_base member. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: hisi: Name private struct pointer "hisi_pcie" consistentlyBjorn Helgaas
Most struct hisi_pcie pointers are already called "hisi_pcie". Change the rest of them to match. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: hisi: Remove unused platform dataBjorn Helgaas
The hisi driver never uses the platform drvdata pointer, so don't bother setting it. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: hisi: Add local struct device pointersBjorn Helgaas
Use a local "struct device *dev" for brevity and consistency with other drivers. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: exynos: Reorder struct exynos_pcieBjorn Helgaas
Reorder struct exynos_pcie to put generic fields first. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: exynos: Pass device-specific struct to internal functionsBjorn Helgaas
Only interfaces used from outside the driver, e.g., those called by the DesignWare core, need to accept pointers to the generic struct pcie_port. Internal interfaces can accept pointers to the device-specific struct, which makes them more straightforward. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: exynos: Name private struct pointer "exynos_pcie" consistentlyBjorn Helgaas
Most struct exynos_pcie pointers are already called "exynos_pcie". Change the rest of them to match. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: exynos: Uninline register accessorsBjorn Helgaas
The register accessors are not performance critical and are small enough that the compiler can inline them itself if it makes sense. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-10-11PCI: dra7xx: Use generic DesignWare accessorsBjorn Helgaas
The dw_pcie_readl_rc() and dw_pcie_writel_rc() interfaces already add in pp->dbi_base, so use those instead of doing it ourselves in the dra7xx driver. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: dra7xx: Set drvdata at end of probe functionBjorn Helgaas
Set the drvdata pointer at the end of probe function for consistency with other drivers. We don't need the drvdata until after the probe completes, and we don't need it at all if the probe fails. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: dra7xx: Remove redundant struct device pointer from dra7xx_pcieBjorn Helgaas
The DesignWare core already stores the struct device pointer in struct pcie_port. Remove the redundant copy from struct dra7xx_pcie.dev. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-10-11PCI: artpec6: Remove unnecessary artpec6_pcie_link_up()Bjorn Helgaas
Remove artpec6_pcie_link_up(); the generic dw_pcie_link_up() does the same thing, so we don't need a device-specific version. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Jesper Nilsson <jesper.nilsson@axis.com>

2016-10-11PCI: armada: Remove redundant struct armada8k_pcie.baseBjorn Helgaas
The struct armada8k_pcie.base pointer is always a constant offset from struct pcie_port.dbi_base. Encode that offset in the register macros so we don't need to maintain the armada8k_pcie.base pointer. No functional change intended.

2016-10-11PCI: altera: Simplify TLP_CFG_DW1 usageBjorn Helgaas
TLP_CFG_DW1() was only used with altera->root_bus_nr and RP_DEVFN, so encode that directly into the macro so we don't have to clutter the uses with the TLP_REQ_ID() usage. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: altera: Simplify TLB_CFG_DW0 usageBjorn Helgaas
All TLP_CFG_DW0() uses follow the same pattern based on the root bus number, so pull that into the macro itself to declutter the users. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-10-11PCI: altera: Remove redundant platform_get_resource() return value checkBjorn Helgaas
devm_ioremap_resource() fails gracefully when given a NULL resource pointer, so we don't need to check separately for failure from platform_get_resource_byname(). Remove the redundant check. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-10-11PCI: designware: Simplify pcie_host_ops.readl_rc() and .writel_rc() interfacesBjorn Helgaas
The struct pcie_host_ops.readl_rc() and .writel_rc() function pointers allow a driver to override the default DesignWare register accessors. Make the signature of the override functions the same as the default accessors. This makes the default dw_pcie_readl_rc() and the corresponding override more structurally similar: both will compute the final register address with "pp->dbi_base + reg". Previously dw_pcie_readl_rc() computed the address and passed it to the override. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
