    Pull ARM SoC driver updates from Arnd Bergmann:
    "As usual, the drivers/tee and drivers/reset subsystems get merged
    here, with the expected set of smaller updates and some new hardware
    support. The tee subsystem now supports device drivers to be attached
    to a tee, the first example here is a random number driver with its
    implementation in the secure world.

    Three new power domain drivers get added for specific chip families:
    - Broadcom BCM283x chips (used in Raspberry Pi)
    - Qualcomm Snapdragon phone chips
    - Xilinx ZynqMP FPGA SoCs

    One new driver is added to talk to the BPMP firmware on NVIDIA
    Tegra210

    Existing drivers are extended for new SoC variants from NXP, NVIDIA,
    Amlogic and Qualcomm"

    Currently for ACPI-based FW we fail the probe for an unrecognised child
    HID.

    However, there is FW in the field with LPC child devices having fake HIDs,
    namely "IPI0002", which was an IPMI device invented to support the
    initial out-of-tree LPC host driver, different from the final mainline
    version.

    To provide compatibility support for these dodgy FWs, just discard the
    unrecognised HIDs instead of failing the probe altogether.

    Commit 84badc5ec5fc ("ARM: dts: omap4: Move l4 child devices to probe
    them with ti-sysc") started producing a warning for pwm-omap-dmtimer:

    WARNING: CPU: 0 PID: 77 at drivers/bus/omap_l3_noc.c:147
    l3_interrupt_handler+0x2f8/0x388
    44000000.ocp:L3 Custom Error: MASTER MPU TARGET L4PER2 (Idle):

    pwm_omap_dmtimer_start
    pwm_omap_dmtimer_enable
    pwm_apply_state
    pwm_vibrator_start
    pwm_vibrator_play_work

    This is because the timer that pwm-omap-dmtimer is using is now being
    probed with ti-sysc interconnect target module instead of omap_device
    and the ti-sysc quirk for SYSC_QUIRK_LEGACY_IDLE is not fully
    compatible with what omap_device has been doing.

    We could fix this by reverting the timer changes and have the timer
    probe again with omap_device. Or we could add more quirk handling to
    ti-sysc driver. But as these options don't work nicely as longer term
    solutions, let's just make timers probe with ti-sysc without any
    quirks.

    To do this, all we need to do is remove quirks for timers for ti-sysc,
    and drop the bogus pm_runtime_irq_safe() flag for timer-ti-dm.

    We should not use pm_runtime_irq_safe() anyways for drivers as it will
    take a permanent use count on the parent device blocking the parent
    devices from idling and has been forcing ti-sysc driver to use a
    quirk flag.

    Note that we will move the timer data to DEBUG section later on in
    clean-up patches.

    Allocatable devices can be acquired by drivers on the fsl-mc bus using
    the fsl_mc_portal_allocate or fsl_mc_object_allocate functions. Add a
    device link between the consumer device and the supplier device so that
    proper resource management is achieved.
    Also, adding a link between these devices ensures that a proper unbind
    order is respected (ie before the supplier device is unbound from its
    respective driver all consumer devices will be notified and unbound
    first).

  • c7995bcb3   bus: imx-weim: guard against timing configuration conflicts ... Browse Code »

    When specifying weim child devices, there is a risk that more than
    one timing setting is specified for the same chip select.

    The driver cannot support such a configuration.

    In case of conflict, this patch will print a warning to the log,
    and will ignore the child node in question.

    In this example, node acme@1 will be ignored, as it tries to modify
    timing settings for CS0:

    &weim {
    acme@0 {
    compatible = "acme,whatever";
    reg = ;
    fsl,weim-cs-timing = ;
    };
    acme@1 {
    compatible = "acme,whatnot";
    reg = ;
    fsl,weim-cs-timing = ;
    };
    };

    However in this example, the driver will be happy:

    &weim {
    acme@0 {
    compatible = "acme,whatever";
    reg = ;
    fsl,weim-cs-timing = ;
    };
    acme@1 {
    compatible = "acme,whatnot";
    reg = ;
    fsl,weim-cs-timing = ;
    };
    };

    Ensure that timing values for the child node are applied to
    all chip selects in the child's address ranges.

    Note that this does not support multiple timing settings per
    child; this can be added in the future if required.

    Example:
    &weim {
    acme@0 {

    With ti-sysc, we need to now have the device tree properties for
    ti,no-reset-on-init and ti,no-idle-on-init at the module level instead
    of the child device level.

    Let's check for these properties at the child device level to enable
    quirks, and warn about moving the properties to the module level.

    Otherwise am335x-evm based boards tagging gpio1 with ti,no-reset-on-init
    will have their DDR power disabled if wired up in such a tricky way.

    Note that this should not be an issue for earlier kernels as we don't
    rely on this until the dts files have been updated to probe with ti-sysc
    interconnect target driver.

    "The most noteworthy SoC driver changes this time include:

    - The TEE subsystem gains an in-kernel interface to access the TEE
    from device drivers.

    - The reset controller subsystem gains a driver for the Qualcomm
    Snapdragon 845 Power Domain Controller.

    - The Xilinx Zynq platform now has a firmware interface for its
    platform management unit. This contains a firmware "ioctl"
    interface that was a little controversial at first, but the version
    we merged solved that by not exposing arbitrary firmware calls to
    user space.

    - The Amlogic Meson platform gains a "canvas" driver that is used for
    video processing and shared between different high-level drivers.

    The rest is more of the usual, mostly related to SoC specific power
    management support and core drivers in drivers/soc:

    - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
    features related to power and reset control.

    - The Mediatek mt8183 and mt6765 SoC platforms gain support for their
    respective power management chips.

    - A new driver for NXP i.MX8, which need a firmware interface for
    power management.

    - The SCPI firmware interface now contains support estimating power
    usage of performance states

    - The NVIDIA Tegra "pmc" driver gains a few new features, in
    particular a pinctrl interface for configuring the pads.

    - Lots of small changes for Qualcomm, in particular the "smem" device
    driver.

    - Some cleanups for the TI OMAP series related to their sysc

    "A bit bigger than normal as I've been busy this cycle.

    There's a few things with dependencies and a few things subsystem
    maintainers didn't pick up, so I'm taking them thru my tree.

    The fixes from Johan didn't get into linux-next, but they've been
    waiting for some time now and they are what's left of what subsystem
    maintainers didn't pick up.

    Summary:

    - Sync dtc with upstream version v1.4.7-14-gc86da84d30e4

    - Work to get rid of direct accesses to struct device_node name and
    type pointers in preparation for removing them. New helpers for
    parsing DT cpu nodes and conversions to use the helpers. printk
    conversions to %pOFn for printing DT node names. Most went thru
    subystem trees, so this is the remainder.

    - Fixes to DT child node lookups to actually be restricted to child
    nodes instead of treewide.

    - Refactoring of dtb targets out of arch code. This makes the support
    more uniform and enables building all dtbs on c6x, microblaze, and
    powerpc.

    - Various DT binding updates for Renesas r8a7744 SoC

    - Vendor prefixes for Facebook, OLPC

    - Restructuring of some ARM binding docs moving some peripheral
    bindings out of board/SoC binding files

    Pull IOMMU updates from Joerg Roedel:

    - Debugfs support for the Intel VT-d driver.

    When enabled, it now also exposes some of its internal data
    structures to user-space for debugging purposes.

    - ARM-SMMU driver now uses the generic deferred flushing and fast-path
    iova allocation code.

    This is expected to be a major performance improvement, as this
    allocation path scales a lot better.

    - Support for r8a7744 in the Renesas iommu driver

    Pull GPIO updates from Linus Walleij:
    "This is the bulk of GPIO changes for the v4.20 series:

    Core changes:

    - A patch series from Hans Verkuil to make it possible to
    enable/disable IRQs on a GPIO line at runtime and drive GPIO lines
    as output without having to put/get them from scratch.

    The irqchip callbacks have been improved so that they can use only
    the fastpatch callbacks to enable/disable irqs like any normal
    irqchip, especially the gpiod_lock_as_irq() has been improved to be
    callable in fastpath context.

    A bunch of rework had to be done to achieve this but it is a big
    win since I never liked to restrict this to slowpath. The only call
    requireing slowpath was try_module_get() and this is kept at the
    .request_resources() slowpath callback. In the GPIO CEC driver this
    is a big win sine a single line is used for both outgoing and
    incoming traffic, and this needs to use IRQs for incoming traffic
    while actively driving the line for outgoing traffic.

    - Janusz Krzysztofik improved the GPIO array API to pass a "cookie"
    (struct gpio_array) and a bitmap for setting or getting multiple
    GPIO lines at once.

    This improvement orginated in a specific need to speed up an OMAP1
    driver and has led to a much better API and real performance gains
    when the state of the array can be used to bypass a lot of checks
    and code when we want things to go really fast.

    The previous code would minimize the number of calls down to the
    driver callbacks assuming the CPU speed was orders of magnitude
    faster than the I/O latency, but this assumption was wrong on
    several platforms: what we needed to do was to profile and improve
    the speed on the hot path of the array functions and this change is
    now completed.

    - Clean out the painful and hard to grasp BNF experiments from the
    device tree bindings. Future approaches are looking into using JSON
    schema for this purpose. (Rob Herring is floating a patch series.)

    New drivers:

    - The RCAR driver now supports r8a774a1 (RZ/G2M).

    - Synopsys GPIO via CREGs driver.

    Major improvements:

    - Modernization of the EP93xx driver to use irqdomain and other
    contemporary concepts.

    - The ingenic driver has been merged into the Ingenic pin control
    driver and removed from the GPIO subsystem.

    - Debounce support in the ftgpio010 driver"

    TI sysc driver changes for v4.20 merge window

    This series gets rid of the SYSC_QUIRK_RESOURCE_PROVIDER to make device
    detection happen mostly only if #define DEBUG is set. Few core devices still
    need to be detected to set legacy quirks.

    We also add support for booting am335x, am437x and dra7 SoCs with L4 devices
    defined in device tree instead of legacy platform data.

    And finally we simplify suspend with just SET_NOIRQ_SYSTEM_SLEEP_PM_OPS
    and dropping the custom functions that were attempting to work around
    issues that really turned out to be child device driver related issues.

    Apologies for a late pull request, debugging the suspend issues took a while
    and I did not want to send these changes until that got sorted out.

    As Grygorii Strashko pointed out, the runtime PM use count of the
    children can be whatever at suspend and we should not use it. So
    let's just suspend ti-sysc at noirq level and get rid of some code.

    Let's also remove the PM_SLEEP ifdef and use __maybe_unused as the
    PM code already deals with the ifdefs.
