2016-10-11PCI: layerscape: Move struct pcie_port setup to probe functionBjorn Helgaas
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 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: layerscape: Remove redundant struct ls_pcie.dbiBjorn Helgaas
Remove the struct ls_pcie.dbi 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: layerscape: Remove unused platform dataBjorn Helgaas
The layerscape 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: layerscape: 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: keystone: Reorder struct keystone_pcieBjorn Helgaas
Reorder struct keystone_pcie to put generic fields first. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: keystone: Add app register accessorsBjorn Helgaas
Add device-specific register accessors for consistency across host drivers. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-11PCI: keystone: Pass keystone_pcie, not va_app_base, to DBI functionsBjorn Helgaas
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 Helgaas
Instead of passing the application register base to IRQ 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: 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 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 Helgaas
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 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

2016-10-11PCI: imx6: Pass struct imx6_pcie to PHY accessorsBjorn Helgaas

2016-10-11PCI: imx6: Removed unused struct imx6_pcie.mem_baseBjorn Helgaas

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: 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>
