      ARM: dts: Configure interconnect target module for omap4 hdmi · 8f661563
      Tony Lindgren authored
      We can now probe devices with device tree only configuration using
      ti-sysc interconnect target module driver. Let's configure the
      module and drop "ti,hwmods" peroperty as this module is a child node
      of dispc and has no dependencies to to legacy platform data.
      
      Note that we must disable smart idle modes for HDMI audio like we've
      done with the legacy platform data. And HDMI needs both hdmi clock
      and dss clock to operate.

      devices are probing with ti-sysc interconnect driver.
      
      The display subsystem (DSS) is in a 16MB interconnect target module
      mapped to l4 and l3 buses. We are only using the l3 port as recommended
      by the TRM. So there is no need to configure l4 ranges like we've done
      for l4 ABE instance for example.
      
      Initially let's just update the top level dss node to probe with ti-sysc
      interconnect target module driver. The child nodes are still children
      of dispc, only the node indentation changes for them now along with
      using the reg range provided by top level dss.
      
      Let's also add add a note about using only the l3 access without l4
      as noted in the TRM.

      bus: ti-sysc: Add support for PRUSS SYSC type · b2745d92
      Suman Anna authored
      The PRU-ICSS present on AM33xx/AM43xx/AM57xx has a very unique
      SYSCFG register. The register follows the OMAP4-style SYSC_TYPE3
      for Master Standby and Slave Idle, but also has two additional
      unique fields - STANDBY_INIT and SUB_MWAIT. The STANDBY_INIT is
      a control bit that is used to initiate a Standby sequence (when
      set) and trigger a MStandby request to the SoC's PRCM module. This
      same bit is also used to enable the OCP master ports (when cleared)
      to allow the PRU cores to access any peripherals or memory beyond
      the PRU subsystem. The SUB_MWAIT is a ready status field for the
      external access.
      
      Add support for this SYSC type. The STANDBY_INIT has to be set
      during suspend, without which it results in a hang in the resume
      sequence on AM33xx/AM43xx boards and requires a board reset to
      come out of the hang. Any PRU applications requiring external
      access are supposed to clear the STANDBY_INIT bit. Note that
      the PRUSS context is lost during a suspend sequence because the
      PRUSS module is reset and/or disabled.

      bus: ti-sysc: Detect EDMA and set quirk flags for tptc · 25bfaaa7
      Tony Lindgren authored
      In order to probe EDMA with ti-sysc interconnect target module and with
      device tree data, we need to properly detect EDMA and set the flags for
      SYSC_QUIRK_SWSUP_SIDLE | SYSC_QUIRK_SWSUP_MSTANDBY for tptc.
      
      We have these flags currently set for am4 and dra7, but not for am335x.
      Let's set them for all the SoCs as the tptc module should behave the
      same for all of them. It's likely that am335x was never tested to idle
      EDMA tptc.

      bus: ti-sysc: Implement display subsystem reset quirk · 7324a7a0
      Tony Lindgren authored
      The display subsystem (DSS) needs the child outputs disabled for reset.
      In order to prepare to probe DSS without legacy platform data, let's
      implement sysc_pre_reset_quirk_dss() similar to what we have for the
      platform data with omap_dss_reset().
      
      Note that we cannot directly use the old omap_dss_reset() without
      platform data callbacks and updating omap_dss_reset() to understand
      struct device. And we will be dropping omap_dss_reset() anyways when
      all the SoCs are probing with device tree, so let's not mess with the
      legacy code at all.

      The RTC modules on am3 and am4 need quirk handling to unlock and lock

      bus: ti-sysc: Implement SoC revision handling · feaa8bae
      Tony Lindgren authored
      We need to know SoC type and features for cases where the same SoC
      may be installed in various versions on the same board and would need
      a separate dts file otherwise for the different variants.
      
      For example, am3703 is pin compatible with omap3630, but has sgx and
      iva accelerators disabled. We must not try to access the sgx or iva
      module registers on am3703, and need to set the unavailable devices
      disabled early.
      
      Let's also detect omap3430 as that is needed for display subsystem
      (DSS) reset later on, and GP vs EMU or HS devices. Further SoC
      specific disabled device detection can be added as needed, such as
      dra71x vs dra76x rtc and usb4.

      bus: ti-sysc: Consider non-existing registers too when matching quirks · 590e15c7
      Tony Lindgren authored
      We are currently setting -1 for non-existing sysconfig related registers
      for quirks, but setting -ENODEV elsewhere. And for matching the quirks,
      we're now just ignoring the non-existing registers. This will cause issues
      with misdetecting DSS registers as the hardware revision numbers can have
      duplicates.
      
      To avoid this, let's standardize on using -ENODEV also for the quirks
      instead of -1. That way we can always just test for a match without adding
      any more complicated logic.

      drm/omap: Prepare DSS for probing without legacy platform data · cef76630
      Tony Lindgren authored
      In order to probe display subsystem (DSS) components with ti-sysc
      interconnect target module without legacy platform data and using
      devicetree, we need to update dss probing a bit.
      
      In the device tree, we will be defining the data also for the interconnect
      target modules as DSS really is a private interconnect. There is some
      information about that in 4460 TRM in "Figure 10-3. DSS Integration" for
      example where it mentions "32-bit interconnect (SLX)".
      
      The changes we need to make are:
      
      1. Parse also device tree subnodes for the compatible property fixup
      
      2. Update the component code to consider device tree subnodes

      Linus Torvalds authored
      Pull new zonefs file system from Damien Le Moal:
       "Zonefs is a very simple file system exposing each zone of a zoned
        block device as a file.
      
        Unlike a regular file system with native zoned block device support
        (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the
        sequential write constraint of zoned block devices to the user. As a
        result, zonefs is not a POSIX compliant file system. Its goal is to
        simplify the implementation of zoned block devices support in
        applications by replacing raw block device file accesses with a richer
        file based API, avoiding relying on direct block device file ioctls
        which may be more obscure to developers.
      
        One example of this approach is the implementation of LSM
        (log-structured merge) tree structures (such as used in RocksDB and
        LevelDB) on zoned block devices by allowing SSTables to be stored in a
        zone file similarly to a regular file system rather than as a range of
        sectors of a zoned device. The introduction of the higher level
        construct "one file is one zone" can help reducing the amount of
        changes needed in the application while at the same time allowing the
        use of zoned block devices with various programming languages other
        than C.
      
        Zonefs IO management implementation uses the new iomap generic code.
        Zonefs has been successfully tested using a functional test suite
        (available with zonefs userland format tool on github) and a prototype
        implementation of LevelDB on top of zonefs"

      Pull x86 fixes from Thomas Gleixner:
       "A set of fixes for X86:
      
         - Ensure that the PIT is set up when the local APIC is disable or
           configured in legacy mode. This is caused by an ordering issue
           introduced in the recent changes which skip PIT initialization when
           the TSC and APIC frequencies are already known.
      
         - Handle malformed SRAT tables during early ACPI parsing which caused
           an infinite loop anda boot hang.
      
         - Fix a long standing race in the affinity setting code which affects
           PCI devices with non-maskable MSI interrupts. The problem is caused
           by the non-atomic writes of the MSI address (destination APIC id)
           and data (vector) fields which the device uses to construct the MSI
           message. The non-atomic writes are mandated by PCI.
      
           If both fields change and the device raises an interrupt after
           writing address and before writing data, then the MSI block
           constructs a inconsistent message which causes interrupts to be
           lost and subsequent malfunction of the device.
      
           The fix is to redirect the interrupt to the new vector on the
           current CPU first and then switch it over to the new target CPU.
           This allows to observe an eventually raised interrupt in the
           transitional stage (old CPU, new vector) to be observed in the APIC
           IRR and retriggered on the new target CPU and the new vector.
      
           The potential spurious interrupts caused by this are harmless and
           can in the worst case expose a buggy driver (all handlers have to
           be able to deal with spurious interrupts as they can and do happen
           for various reasons).
      
         - Add the missing suspend/resume mechanism for the HYPERV hypercall
           page which prevents resume hibernation on HYPERV guests. This
           change got lost before the merge window.
      
         - Mask the IOAPIC before disabling the local APIC to prevent
           potentially stale IOAPIC remote IRR bits which cause stale
           interrupt lines after resume"

      fs: Add VirtualBox guest shared folder (vboxsf) support · 0fd16957
      Hans de Goede authored
      VirtualBox hosts can share folders with guests, this commit adds a
      VFS driver implementing the Linux-guest side of this, allowing folders
      exported by the host to be mounted under Linux.
      
      This driver depends on the guest <-> host IPC functions exported by
      the vboxguest driver.

      Fix up remaining devm_ioremap_nocache() in SGI IOC3 8250 UART driver · b0ef7cda
      Linus Torvalds authored
      This is a merge error on my part - the driver was merged into mainline
      by commit c5951e7c ("Merge tag 'mips_5.6' of git://../mips/linux")
      over a week ago, but nobody apparently noticed that it didn't actually
      build due to still having a reference to the devm_ioremap_nocache()
      function, removed a few days earlier through commit 6a1000bd ("Merge
      tag 'ioremap-5.6' of git://../ioremap").
      
      Apparently this didn't get any build testing anywhere.  Not perhaps all
      that surprising: it's restricted to 64-bit MIPS only, and only with the
      new SGI_MFD_IOC3 support enabled.
      
      I only noticed because the ioremap conflicts in the ARM SoC driver
      update made me check there weren't any others hiding, and I found this
      one.
