2017-08-29PCI: endpoint: Add "volatile" to pci_epf_test_regKishon Vijay Abraham I
struct pci_epf_test_reg is the MEMSPACE of pci-epf-test function driver that will be accessed by the "host" for programming the pci-epf-test device. So this structure shouldn't be subjected to compiler optimization in pci_epf_test_cmd_handler() since the values can be changed by code outside the scope of current code at any time.

pci-epc-mem uses a page size equal to *PAGE_SIZE* (usually 4KB) to manage the address space. However certain platforms like TI's K2G have a restriction that this address space should be either divided into 1MB/2MB/4MB or 8MB sizes (Ref: 11.14.4.9.1 Outbound Address Translation in K2G TRM SPRUHY8F January 2016 – Revised May 2017).

2017-08-29i2c: ismt: Don't duplicate the receive length for block readsStephen Douthit
According to Table 15-14 of the C2000 EDS (Intel doc #510524) the rx data pointed to by the descriptor dptr contains the byte count. desc->rxbytes reports all bytes read on the wire, including the "byte count" byte. So if a device sends 4 bytes in response to a block read, on the wire and in the DMA buffer we see: count data1 data2 data3 data4 0x04 0xde 0xad 0xbe 0xef That's what we want to return in data->block to the next level. Instead we were actually prefixing that with desc->rxbytes: bad count count data1 data2 data3 data4 0x05 0x04 0xde 0xad 0xbe 0xef This was discovered while developing a BMC solution relying on the ipmi_ssif.c driver which was trying to interpret the bogus length field as part of the IPMI response.

2017-08-29spi: imx: fix use of native chip-selects with devicetreeGreg Ungerer
The commonly used mechanism of specifying the hardware or native chip-select on an SPI device in devicetree (that is "cs-gpios = <0>") does not result in the native chip-select being configured for use. So external SPI devices that require use of the native chip-select will not work. You can successfully specify native chip-selects if using a platform setup by specifying the cs-gpio as negative offset by 32. And that works correctly. You cannot use the same method in devicetree. The logic in the spi-imx.c driver during probe uses core spi function of_spi_register_master() in spi.c to parse the "cs-gpios" devicetree tag. For valid GPIO values that will be recorded for use, all other entries in the cs_gpios list will be set to -ENOENT. So entries like "<0>" will be set to -ENOENT in the cs_gpios list. When the SPI device registers are setup the code will use the GPIO listed in the cs_gpios list for the desired chip-select. If the cs_gpio is less then 0 then it is intended to be for a native chip-select, and its cs_gpio value is added to 32 to get the chipselect number to use. Problem is that with devicetree this can only ever be -ENOENT (which is -2), and that alone results in an invalid chip-select number. But also doesn't allow selection of the native chip-select at all. To fix, if the cs_gpio specified for this spi device is not a valid GPIO then use the "chip_select" (that is the native chip-select number) for hardware setup.

2017-08-29ASoC: tas2552: Fix fraction overflow in PLL calculationOskar Schirmer
Setting the PLL involves the calculation of a fixed point ratio with 4 decimal digits fraction, referred to as "J.D". The fraction "D" is stored separately from the integer part "J" and is limited to 0..9999. The current algorithm uses integer registers to calculate the fraction part, but failed to compensate for rounding errors, resulting in values larger than 9999 for the fraction part occasionally, e.g. for 44.1kHz audio rate and pll_clkin = 3763400 it would set J to 11 and D to 10002, which will at best result in wrong pitch. The critical part is the "pll_clkin / 10000", which would be ok with real numbers, but using integer arithmetic the rounding decreases the divisor, thus increasing the final quotient. The issue is solved by linear interpolation over the reciprocal function between the two adjacent points with integer divisor, i.e. pll_clkin / 10000 and pll_clkin / 10000 + 1, and doing all rounding to the lower result. As a side effect to the bug fix, the approximation to the desired frequency is much better, for the above mentioned example we get 11.9993, while the true ratio is 11.9993623.

2017-08-29PCI: Wait up to 60 seconds for device to become ready after FLRSinan Kaya
Sporadic reset issues have been observed with an Intel 750 NVMe drive while assigning the physical function to the guest machine. The sequence of events observed is as follows: - perform a Function Level Reset (FLR) - sleep up to 1000ms total - read ~0 from PCI_COMMAND (CRS completion for config read) - warn that the device didn't return from FLR - touch the device before it's ready - device drops config writes when we restore register settings (there's no mechanism for software to learn about CRS completions for writes) - incomplete register restore leaves device in inconsistent state - device probe fails because device is in inconsistent state After reset, an endpoint may respond to config requests with Configuration Request Retry Status (CRS) to indicate that it is not ready to accept new requests. See PCIe r3.1, sec 2.3.1 and 6.6.2. Increase the timeout value from 1 second to 60 seconds to cover the period where device responds with CRS and also report polling progress.

2017-08-29PCI: Always check for non-CRS response before timeoutBjorn Helgaas
While waiting for a device to become ready (i.e., to return a non-CRS completion to a read of its Vendor ID), if we got a valid response to the very last read before timing out, we printed a warning and gave up on the device even though it was actually ready. For a typical 60s timeout, we wait about 65s (it's not exact because of the exponential backoff), but we treated devices that became ready between 33s and 65s as though they failed. Move the Device ID read later so we check whether the device is ready before checking for a timeout. Thanks to Sinan Kaya <okaya@codeaurora.org>, reorder reads so we always check device presence after sleep, since it's pointless to sleep unless we recheck afterwards.

2017-08-29PCI: rockchip: Clean up PHY if driver probe or resume failsShawn Lin
We observed that the clk_pciephy_ref is still enabled when we fail to probe the driver. root@linaro-alip:~# grep pcie /sys/kernel/debug/clk/clk_summary clk_pciephy_ref 1 1 24000000 0 0 clk_pcie_pm 0 0 24000000 0 0 clk_pcie_core_cru 0 0 125000000 0 0 clk_pciephy_ref100m 0 0 100000000 0 0 aclk_pcie 0 0 148500000 0 0 aclk_perf_pcie 0 0 148500000 0 0 pclk_pcie 0 0 37125000 0 0 clk_pcie_core 0 0 0 0 0 clk_pciephy_ref is used by the PHY driver and we need to properly disable it for this case. Add error handling in rockchip_pcie_init_port() and rockchip_pcie_resume_noirq() to fix this issue.

2017-08-29PCI: rockchip: Factor out rockchip_pcie_deinit_phys()Shawn Lin
Factor out rockchip_pcie_deinit_phys() so it can be reused by rockchip_pcie_suspend_noirq() and rockchip_pcie_remove(). No functional change intended. Signed-off-by: Shawn Lin <shawn.lin@rock-chips.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
