2016-10-11PCI: rcar: Remove unused rcar_pcie_get_resources() platform_device argBjorn Helgaas1-3/+2
rcar_pcie_get_resources() doesn't use the platform_device pointer passed to it, so remove it. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Acked-by: Simon Horman <horms+renesas@verge.net.au>
2016-10-11PCI: rcar: Remove unused platform dataBjorn Helgaas1-1/+0
The rcar 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> Acked-by: Simon Horman <horms+renesas@verge.net.au>

2016-10-11PCI: mvebu: Use existing of_node pointerBjorn Helgaas1-2/+2
Use the existing "np" pointer instead of looking up dev->of_node again. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: mvebu: Add local struct device pointersBjorn Helgaas1-12/+9

2016-10-11PCI: layerscape: Remove unused ls_add_pcie_port() platform_device argBjorn Helgaas1-3/+2

2016-10-11PCI: layerscape: Move struct pcie_port setup to probe functionBjorn Helgaas1-4/+6
Do the basic pcie_port setup in the probe function for consistency with other drivers. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: layerscape: Pass device-specific struct to internal functionsBjorn Helgaas1-3/+3
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: layerscape: Remove redundant struct ls_pcie.dbiBjorn Helgaas1-13/+11

2016-10-11PCI: keystone: Pass keystone_pcie, not va_app_base, to DBI functionsBjorn Helgaas1-12/+12
Instead of passing ks_pcie->va_app_base to DBI mode functions, pass the struct keystone_pcie. This will allow them to use register accessors. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: keystone: Pass keystone_pcie, not address, to IRQ functionsBjorn Helgaas3-13/+12

2016-10-11PCI: keystone: Use generic DesignWare accessorsBjorn Helgaas1-6/+7
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 keystone driver. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-10-11PCI: iproc: Hard-code PCIe capability offset instead of searchingBjorn Helgaas1-6/+5
We know where the PCIe capability lives in the host bridge's config space; in fact, we already hard-coded the offset of the Link Control 2 register. The hard-coded Link Control 2 offset was 0xdc. Link Control 2 is at offset 0x30 into the PCIe capability, so the capability itself must be at 0xdc - 0x30 = 0xac. Hard-code the PCIe capability offset, which means we don't have to search for it and we can use the standard definitions for registers within the capability. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: iproc: Remove redundant null pointer checkingBjorn Helgaas1-3/+0
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 Helgaas2-1/+6
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 Helgaas2-2/+2
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 Helgaas3-32/+38

2016-10-11PCI: imx6: Remove redundant of_node pointerBjorn Helgaas1-4/+3
"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: Name private struct pointer "hisi_pcie" consistentlyBjorn Helgaas1-13/+13
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: exynos: Uninline register accessorsBjorn Helgaas1-8/+8
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>
