pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to pm_runtime_put_noidle will result in reference leak in mxs_spi_probe, so we should fix it.

2020-11-11spi: introduce SPI_MODE_X_MASK macroOleksij Rempel
Provide a macro to filter all SPI_MODE_0,1,2,3 mode in one run. The latest SPI framework will parse the devicetree in following call sequence: of_register_spi_device() -> of_spi_parse_dt() So, driver do not need to pars the devicetree and will get prepared flags in the probe. On one hand it is good far most drivers. On other hand some drivers need to filter flags provide by SPI framework and apply know to work flags. This drivers may use SPI_MODE_X_MASK to filter MODE flags and set own, known flags: spi->flags &= ~SPI_MODE_X_MASK; spi->flags |= SPI_MODE_0; Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> Link: https://lore.kernel.org/r/20201027095724.18654-2-o.rempel@pengutronix.de Signed-off-by: Mark Brown <broonie@kernel.org>

2020-10-30spi: atmel: Downgrade to dev_dbg when dma_request_chan() failsTudor Ambarus
The IP's DMA capabilities are described in the SoC dtsi, to spare users duplicating the DMA bindings in their board device tree. Users that don't want to use DMA, have to overwrite the DMA bindings in their board device tree. An example is: commit ddcdaeb88242 ("ARM: dts: at91: sama5d2: Add DMA bindings for the SPI and UART flx4 functions") When the DMA bindings are overwritten, one could see on the console: atmel_spi fc018400.spi: error -ENODEV: No TX DMA channel, DMA is disabled atmel_spi fc018400.spi: Atmel SPI Controller using PIO only Choosing to not use DMA is not a reason to print an error message.

Enabling autosuspend mode causes the controller to not suspend between SPI transfers and the delays disappear.

git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux Pull more parisc updates from Helge Deller: - During this merge window O_NONBLOCK was changed to become 000200000, but we missed that the syscalls timerfd_create(), signalfd4(), eventfd2(), pipe2(), inotify_init1() and userfaultfd() do a strict bit-wise check of the flags parameter. To provide backward compatibility with existing userspace we introduce parisc specific wrappers for those syscalls which filter out the old O_NONBLOCK value and replaces it with the new one. - Prevent HIL bus driver to get stuck when keyboard or mouse isn't attached - Improve error return codes when setting rtc time - Minor documentation fix in pata_ns87415.c * 'parisc-5.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: ata: pata_ns87415.c: Document support on parisc with superio chip parisc: Add wrapper syscalls to fix O_NONBLOCK flag usage hil/parisc: Disable HIL driver when it gets stuck parisc: Improve error return codes when setting rtc time

git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/prandom Pull random32 updates from Willy Tarreau: "Make prandom_u32() less predictable. This is the cleanup of the latest series of prandom_u32 experimentations consisting in using SipHash instead of Tausworthe to produce the randoms used by the network stack. The changes to the files were kept minimal, and the controversial commit that used to take noise from the fast_pool (f227e3ec3b5c) was reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is fed from various sources of activities (networking, scheduling) to perturb the SipHash state using fast, non-trivially predictable data, instead of keeping it fully deterministic. The goal is essentially to make any occasional memory leakage or brute-force attempt useless. The resulting code was verified to be very slightly faster on x86_64 than what is was with the controversial commit above, though this remains barely above measurement noise. It was also tested on i386 and arm, and build- tested only on arm64" Link: https://lore.kernel.org/netdev/20200808152628.GA27941@SDF.ORG/ * tag '20201024-v4-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/prandom: random32: add a selftest for the prandom32 code random32: add noise from network and scheduling activity random32: make prandom_u32() output unpredictable
2020-10-25i2c: core: Restore acpi_walk_dep_device_list() getting called after ↵Hans de Goede
registering the ACPI i2c devs Commit 21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler() before i2c_acpi_register_devices()")'s intention was to only move the acpi_install_address_space_handler() call to the point before where the ACPI declared i2c-children of the adapter where instantiated by i2c_acpi_register_devices(). But i2c_acpi_install_space_handler() had a call to acpi_walk_dep_device_list() hidden (that is I missed it) at the end of it, so as an unwanted side-effect now acpi_walk_dep_device_list() was also being called before i2c_acpi_register_devices(). Move the acpi_walk_dep_device_list() call to the end of i2c_acpi_register_devices(), so that it is once again called *after* the i2c_client-s hanging of the adapter have been created. This fixes the Microsoft Surface Go 2 hanging at boot.
