2017-04-28misc: Add host side PCI driver for PCI test function deviceKishon Vijay Abraham I
Add PCI endpoint test driver that can verify base address register, legacy interrupt/MSI interrupt and read/write/copy buffers between host and device. The corresponding pci-epf-test function driver should be used on the EP side. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2017-04-28PCI: dwc: dra7xx: Workaround for errata id i870Kishon Vijay Abraham I
According to errata i870, access to the PCIe slave port that are not 32-bit aligned will result in incorrect mapping to TLP Address and Byte enable fields. Accessing non 32-bit aligned data causes incorrect data in the target buffer if memcpy is used. Implement the workaround for this errata here.

2017-04-28PCI: dwc: dra7xx: Facilitate wrapper and MSI interrupts to be enabled ↵Kishon Vijay Abraham I
independently No functional change. Split dra7xx_pcie_enable_interrupts() into dra7xx_pcie_enable_wrapper_interrupts() and dra7xx_pcie_enable_msi_interrupts() so that wrapper interrupts and MSI interrupts can be enabled independently. This is in preparation for adding EP mode support to dra7xx driver since EP mode doesn't have to enable msi_interrupts.

2017-04-28staging: atomisp: remove #ifdef for runtime PM functionsArnd Bergmann
The runtime power management functions are called from the reset handler even if CONFIG_PM is disabled, leading to a link error: drivers/staging/built-in.o: In function `atomisp_reset': (.text+0x4cd1c): undefined reference to `atomisp_runtime_suspend' drivers/staging/built-in.o: In function `atomisp_reset': (.text+0x4cd3a): undefined reference to `atomisp_mrfld_power_down' drivers/staging/built-in.o: In function `atomisp_reset': (.text+0x4cd58): undefined reference to `atomisp_mrfld_power_up' drivers/staging/built-in.o: In function `atomisp_reset': (.text+0x4cd77): undefined reference to `atomisp_runtime_resume' Removing the #ifdef around the PM functions avoids the problem, and lets us simplify it further. The __maybe_unused annotation is needed to ensure the compiler can silently drop the unused callbacks.

We don't need any of these indirections as we only support one MMU type. Start by getting rid of the init/clear/free ones. The init ordering check we already pushed down in a previous patch.
