2016-10-11PCI: iproc: Remove redundant null pointer checkingBjorn Helgaas
The callers never pass a null "pcie" pointer (they check for kzalloc failure), so we don't need to check here. The bus driver should never call the probe function with a null ->dev pointer, so we don't need to check that either. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: iproc: Validate CSR base in BCMA setup codeBjorn Helgaas
Validate iproc_pcie->base for BCMA devices just like we already do for platform devices in iproc_pcie_pltfm_probe(). No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: iproc: 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: iproc: 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: imx6: 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 imx6 driver. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: imx6: 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: imx6: Pass struct imx6_pcie to PHY accessorsBjorn Helgaas
Pass the struct imx6_pcie pointer, not dbi_base address, to PHY accessors. This enables future simplifications. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-10-11PCI: imx6: Remove redundant of_node pointerBjorn Helgaas
"np" and "node" are redundant copies of the of_node pointer. Remove "np" and use "node" instead. Replace the "fsl,max-link-speed" use with "node" as well. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-10-11PCI: hisi: Remove redundant struct hisi_pcie.reg_baseBjorn Helgaas

2016-10-11PCI: hisi: Name private struct pointer "hisi_pcie" consistentlyBjorn Helgaas

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>
