2018-12-18PCI: dwc: Don't hard-code DBI/ATU offsetStephen Warren4-8/+35
The DWC PCIe core contains various separate register spaces: DBI, DBI2, ATU, DMA, etc. The relationship between the addresses of these register spaces is entirely determined by the implementation of the IP block, not by the IP block design itself. Hence, the DWC driver must not make assumptions that one register space can be accessed at a fixed offset from any other register space. To avoid such assumptions, introduce an explicit/separate register pointer for the ATU register space. In particular, the current assumption is not valid for NVIDIA's T194 SoC. The ATU register space is only used on systems that require unrolled ATU access. This property is detected at run-time for host controllers, and when this is detected, this patch provides a default value for atu_base that matches the previous assumption re: register layout. An alternative would be to update all drivers for HW that requires unrolled access to explicitly set atu_base. However, it's hard to tell which drivers would require atu_base to be set. The unrolled property is not detected for endpoint systems, and so any endpoint driver that requires unrolled access must explicitly set the iatu_unroll_enabled flag (none do at present), and so a check is added to require the driver to also set atu_base while at it.

This is similar to imx7d with a few differences: * The PM_Turn_Off bit is exposed through an IOMUX GPR, like all other pcie control bits on 6sx. * The pcie_inbound_axi clk needs to be turned off in suspend. On resume it is restored via resume -> deassert_core_reset -> enable_ref_clk. Most of the resume logic is shared with the initial reset after probe.

On some chips the PCIe and PCIE_PHY blocks are in separate power domains which can be power-gated independently. The PCI driver needs to handle this by keeping both domain active. This is intended for imx6sx where PCIe is in DISPLAY and PCIE_PHY in its own domain. Defining the DISPLAY domain requires a way for PCIe to keep it active or it will break when displays are off. The power-domains on imx6sx are meant to look like this: power-domains = <&pd_disp>, <&pd_pci>; power-domain-names = "pcie", "pcie_phy"; Signed-off-by: Leonard Crestez <leonard.crestez@nxp.com> [lorenzo.pieralisi@arm.com: updated commit log] Signed-off-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com> Reviewed-by: Ulf Hansson <ulf.hansson@linaro.org>

2018-12-13switchtec: Add MRPC DMA mode supportWesley Sheng2-10/+114
MRPC normal mode requires the host to read the MRPC command status and output data from BAR. This results in high latency responses from the Memory Read TLP and potential Completion Timeout (CTO). Add support for MRPC DMA mode, including related macro definitions and data structures and code to: * Retrieve MRPC DMA mode version from adapter firmware * Allocate DMA buffer, register ISR, and enable DMA during init * Check MRPC execution status and get execution results from DMA buffer * Release DMA buffer and disable DMA function when unloading module MRPC DMA mode is a new feature of firmware, and the driver will fall back to MRPC normal mode if there is no support in the legacy firmware. Add a module parameter, "use_dma_mrpc", to select between MRPC DMA mode and MRPC normal mode. Since the driver automatically detects DMA support in the firmware, this parameter is just for debugging and testing. Include <linux/io-64-nonatomic-lo-hi.h> so that readq/writeq is replaced by two readl/writel on systems that do not support it.

The MRPC Input buffer is mostly memory without any side effects, so we can improve the access time by enabling write combining on this region of the BAR. In a few places, we still need to flush the WC buffer. To do this, we simply read from the Outbound Doorbell register because reads to this register are processed by low latency hardware.

2018-12-12switchtec: Remove immediate status check after submitting MRPC commandKelvin Cao1-4/+0
After submitting a Firmware Download MRPC command, Switchtec firmware will delay Management EP BAR MemRd TLP responses by more than 10ms. This is a firmware limitation. Delayed MemRd completions are a problem for systems with a low Completion Timeout (CTO). The current driver checks the MRPC status immediately after submitting an MRPC command, which results in a delayed MemRd completion that may cause a Completion Timeout. Remove the immediate status check and rely on the check after receiving an interrupt or timing out. This is only a software workaround to the READ issue and a proper fix of this should be done in firmware.

2018-12-12PCI / PM: Allow runtime PM without callback functionsJarkko Nikula1-15/+12
a9c8088c7988 ("i2c: i801: Don't restore config registers on runtime PM") nullified the runtime PM suspend/resume callback pointers while keeping the runtime PM enabled. This caused the SMBus PCI device to stay in D0 with /sys/devices/.../power/runtime_status showing "error" when the runtime PM framework attempted to autosuspend the device. This is due to PCI bus runtime PM, which checks for driver runtime PM callbacks and returns -ENOSYS if they are not set. Since i2c-i801.c doesn't need to do anything device-specific for runtime PM, Jean Delvare proposed this be fixed in the PCI core rather than adding dummy runtime PM callback functions in the PCI drivers. Change pci_pm_runtime_suspend()/pci_pm_runtime_resume() so they allow changing the PCI device power state during runtime PM transitions even if the driver supplies no runtime PM callbacks. This fixes the runtime PM regression on i2c-i801.c. It is not obvious why the code previously required the runtime PM callbacks. The test has been there since the code was introduced by 6cbf82148ff2 ("PCI PM: Run-time callbacks for PCI bus type"). On the other hand, a similar change was done to generic runtime PM callbacks in 05aa55dddb9e ("PM / Runtime: Lenient generic runtime pm callbacks").
