2020-03-25libata: Assign OF node to the SCSI deviceLinus Walleij
When we spawn a SCSI device from an ATA device in libata-scsi the SCSI device had no relation to the device tree. The DT binding allows us to define port nodes under a PATA (IDE) or SATA host controller, so we can have proper device nodes for these devices. If OF is enabled, walk the children of the host controller node to see if there is a valid device tree node to assign. The reg is used to match to ID 0 for the master device and ID 1 for the slave device. The corresponding device tree bindings have been accepted by the device tree maintainers.

Fix by removing the the scsi_host_put() calls in ata_scsi_add_hosts() and leave this to ata_devres_release().

And then there also changes to handle RTC, EDMA and PRUSS: - Add module unlock quirk for RTC - Detect EDMA modules - Add support for handling PRUSS * tag 'omap-for-v5.7/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: bus: ti-sysc: Add support for PRUSS SYSC type dt-bindings: bus: ti-sysc: Add support for PRUSS SYSC type bus: ti-sysc: Detect EDMA and set quirk flags for tptc bus: ti-sysc: Fix wrong offset for display subsystem reset quirk bus: ti-sysc: Implement display subsystem reset quirk bus: ti-sysc: Detect display subsystem related devices bus: ti-sysc: Handle module unlock quirk needed for some RTC bus: ti-sysc: Implement SoC revision handling bus: ti-sysc: Don't warn about legacy property for nested ti-sysc devices bus: ti-sysc: Consider non-existing registers too when matching quirks bus: ti-sysc: Improve reset to work with modules with no sysconfig bus: ti-sysc: Rename clk related quirks to pre_reset and post_reset quirks bus: ti-sysc: Fix 1-wire reset quirk drm/omap: Prepare DSS for probing without legacy platform data Link: https://lore.kernel.org/r/pull-1583511417-919838@atomide.com-3 Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2020-03-25cpu/hotplug: Hide cpu_up/down()Qais Yousef
Use separate functions for the device core to bring a CPU up and down. Users outside the device core must use add/remove_cpu() which will take care of extra housekeeping work like keeping sysfs in sync. Make cpu_up/down() static and replace the extra layer of indirection.

2020-03-25firmware: psci: Replace cpu_up/down() with add/remove_cpu()Qais Yousef
The core device API performs extra housekeeping bits that are missing from directly calling cpu_up/down(). See commit a6717c01ddc2 ("powerpc/rtas: use device model APIs and serialization during LPM") for an example description of what might go wrong. This also prepares to make cpu_up/down a private interface of the CPU subsystem.

2020-03-25ACPI: PM: s2idle: Refine active GPEs checkRafael J. Wysocki
The check for any active GPEs added by commit fdde0ff8590b ("ACPI: PM: s2idle: Prevent spurious SCIs from waking up the system") turns out to be insufficiently precise to prevent some systems from resuming prematurely due to a spurious EC wakeup, so refine it by first checking if any GPEs other than the EC GPE are active and skipping all of the SCIs coming from the EC that do not produce any genuine wakeup events after processing.

2020-03-25ACPICA: Allow acpi_any_gpe_status_set() to skip one GPERafael J. Wysocki
The check carried out by acpi_any_gpe_status_set() is not precise enough for the suspend-to-idle implementation in Linux and in some cases it is necessary make it skip one GPE (specifically, the EC GPE) from the check to prevent a race condition leading to a premature system resume from occurring. For this reason, redefine acpi_any_gpe_status_set() to take the number of a GPE to skip as an argument.
