cf2d213e49 Power management updates for 5.3-rc1
- Improve the handling of shared ACPI power resources in the PCI
    bus type layer (Mika Westerberg).
 
  - Make the PCI layer take link delays required by the PCIe spec
    into account as appropriate and avoid polling devices in D3cold
    for PME (Mika Westerberg).
 
  - Fix some corner case issues in ACPI device power management and
    in the PCI bus type layer, optimiza and clean up the handling of
    runtime-suspended PCI devices during system-wide transitions to
    sleep states (Rafael Wysocki).
 
  - Rework hibernation handling in the ACPI core and the PCI bus type
    to resume runtime-suspended devices before hibernation (which
    allows some functional problems to be avoided) and fix some ACPI
    power management issues related to hiberation (Rafael Wysocki).
 
  - Extend the operating performance points (OPP) framework to support
    a wider range of devices (Rajendra Nayak, Stehpen Boyd).
 
  - Fix issues related to genpd_virt_devs and issues with platforms
    using the set_opp() callback in the OPP framework (Viresh Kumar,
    Dmitry Osipenko).
 
  - Add new cpufreq driver for Raspberry Pi (Nicolas Saenz Julienne).
 
  - Add new cpufreq driver for imx8m and imx7d chips (Leonard Crestez).
 
  - Fix and clean up the pcc-cpufreq, brcmstb-avs-cpufreq, s5pv210,
    and armada-37xx cpufreq drivers (David Arcari, Florian Fainelli,
    Paweł Chmiel, YueHaibing).
 
  - Clean up and fix the cpufreq core (Viresh Kumar, Daniel Lezcano).
 
  - Fix minor issue in the ACPI system sleep support code and export
    one function from it (Lenny Szubowicz, Dexuan Cui).
 
  - Clean up assorted pieces of PM code and documentation (Kefeng Wang,
    Andy Shevchenko, Bart Van Assche, Greg Kroah-Hartman, Fuqian Huang,
    Geert Uytterhoeven, Mathieu Malaterre, Rafael Wysocki).
 
  - Update the pm-graph utility to v5.4 (Todd Brandt).

521a503f52 soc: ti: fix irq-ti-sci link error
The irqchip driver depends on the SoC specific driver, but we want
to be able to compile-test it elsewhere:

WARNING: unmet direct dependencies detected for TI_SCI_INTA_MSI_DOMAIN
  Depends on [n]: SOC_TI [=n]
  Selected by [y]:
  - TI_SCI_INTA_IRQCHIP [=y] && TI_SCI_PROTOCOL [=y]

irq-ti-sci-inta.c:(.text+0x204): undefined reference to `ti_sci_inta_msi_create_irq_domain'

Rearrange the Kconfig and Makefile so we build the soc driver whenever
its users are there, regardless of the SOC_TI option.

c884d8ac7f SPDX update for 5.2-rc6
Another round of SPDX updates for 5.2-rc6
 
 Here is what I am guessing is going to be the last "big" SPDX update for
 5.2.  It contains all of the remaining GPLv2 and GPLv2+ updates that
 were "easy" to determine by pattern matching.  The ones after this are
 going to be a bit more difficult and the people on the spdx list will be
 discussing them on a case-by-case basis now.
 
 Another 5000+ files are fixed up, so our overall totals are:
 	Files checked:            64545
 	Files with SPDX:          45529
 
 Compared to the 5.1 kernel which was:
 	Files checked:            63848
 	Files with SPDX:          22576
 This is a huge improvement.
 
 Also, we deleted another 20000 lines of boilerplate license crud, always
 nice to see in a diffstat.

blindly continuing with the initialization. This fixes a NULL pointer

4d28ba1d62 cpufreq: Add imx-cpufreq-dt driver
Right now in upstream imx8m cpufreq support just lists a common subset
of OPPs because the higher ones should only be attempted after checking
speed grading in fuses.

Add a small driver which checks speed grading from nvmem cells before
registering cpufreq-dt.

This driver allows unlocking all frequencies for imx8mm and imx8mq and
could be applied to other chips like imx7d

Pull more power management updates from Rafael Wysocki:
 "These fix a recent regression causing kernels built with CONFIG_PM
  unset to crash on systems that support the Performance and Energy Bias
  Hint (EPB), clean up the cpufreq core and some users of transition
  notifiers and introduce a new power domain flag into the generic power
  domains framework (genpd).

  Specifics:

   - Fix recent regression causing kernels built with CONFIG_PM unset to
     crash on systems that support the Performance and Energy Bias Hint
     (EPB) by avoiding to compile the EPB-related code depending on
     CONFIG_PM when it is unset (Rafael Wysocki).

   - Clean up the transition notifier invocation code in the cpufreq
     core and change some users of cpufreq transition notifiers
     accordingly (Viresh Kumar).

   - Change MAINTAINERS to cover the schedutil governor as part of
     cpufreq (Viresh Kumar).

   - Simplify cpufreq_init_policy() to avoid redundant computations (Yue
     Hu).

   - Add explanatory comment to the cpufreq core (Rafael Wysocki).

   - Introduce a new flag, GENPD_FLAG_RPM_ALWAYS_ON, to the generic
     power domains (genpd) framework along with the first user of it
     (Leonard Crestez)"

49b323157b soc: ti: Add MSI domain bus support for Interrupt Aggregator
With the system coprocessor managing the range allocation of the
inputs to Interrupt Aggregator, it is difficult to represent
the device IRQs from DT.

The suggestion is to use MSI in such cases where devices wants
to allocate and group interrupts dynamically.

Create a MSI domain bus layer that allocates and frees MSIs for
a device.

APIs that are implemented:
- ti_sci_inta_msi_create_irq_domain() that creates a MSI domain
- ti_sci_inta_msi_domain_alloc_irqs() that creates MSIs for the
  specified device and resource.
- ti_sci_inta_msi_domain_free_irqs() frees the irqs attached to the device.
- ti_sci_inta_msi_get_virq() for getting the virq attached to a specific event.

a84014e1db soc: sunxi: Fix missing dependency on REGMAP_MMIO
When enabling ARCH_SUNXI from allnoconfig, SUNXI_SRAM is enabled, but
not REGMAP_MMIO, so the kernel fails to link with an undefined reference
to __devm_regmap_init_mmio_clk. Select REGMAP_MMIO, as suggested in
drivers/base/regmap/Kconfig.

This creates the following dependency loop:

  drivers/of/Kconfig:68:                symbol OF_IRQ depends on IRQ_DOMAIN
  kernel/irq/Kconfig:63:                symbol IRQ_DOMAIN is selected by REGMAP
  drivers/base/regmap/Kconfig:7:        symbol REGMAP default is visible depending on REGMAP_MMIO
  drivers/base/regmap/Kconfig:39:       symbol REGMAP_MMIO is selected by SUNXI_SRAM
  drivers/soc/sunxi/Kconfig:4:          symbol SUNXI_SRAM is selected by USB_MUSB_SUNXI
  drivers/usb/musb/Kconfig:63:          symbol USB_MUSB_SUNXI depends on GENERIC_PHY
  drivers/phy/Kconfig:7:                symbol GENERIC_PHY is selected by PHY_BCM_NS_USB3
  drivers/phy/broadcom/Kconfig:29:      symbol PHY_BCM_NS_USB3 depends on MDIO_BUS
  drivers/net/phy/Kconfig:12:           symbol MDIO_BUS default is visible depending on PHYLIB
  drivers/net/phy/Kconfig:181:          symbol PHYLIB is selected by ARC_EMAC_CORE
  drivers/net/ethernet/arc/Kconfig:18:  symbol ARC_EMAC_CORE is selected by ARC_EMAC
  drivers/net/ethernet/arc/Kconfig:24:  symbol ARC_EMAC depends on OF_IRQ

To fix the circular dependency, make USB_MUSB_SUNXI select GENERIC_PHY
instead of depending on it. This matches the use of GENERIC_PHY by all
but two other drivers.

990d4322cc soc/tegra: Changes for v5.2-rc1
Besides a couple of fixes to better cope with deferred probing, this set
 of patches also implements the acquire/release protocol for resets used
 during powergate operations. This is necessary to allow these resets to
 be temporarily shared with other devices that may also need to control
 these resets.

0065198e67 PM changes for am335x and am437x
This series adds support for am437x RTC-only mode in suspend. In the
 RTC-only mode suspend, everything is shut down except the RTC. This
 makes the power consumption very low for suspend mode.
 
 To support RTC-only mode, we need to export omap_rtc_power_off_program()
 from the rtc driver and improve PM code to save and restore the wkup
 domain context. As RTC-only mode depends on the device being wired
 properly for things like memory, we need to also check for the machine
 type before we allow it. We also need to run DDR3 hardware leveling on
 resume.
 
 Note that there is a trivial merge conflict between the RTC branch
 and these changes where the RTC branch makes tm2bcd() a void function
 and the error handling parts can be just dropped.

This makes the queue manager driver able to probe from the device
tree. It only needs to get a memory resource and two interrupts
and the platform device provides these as resources, so all is
pretty simple.

ecc133c6da soc: ixp4xx: qmgr: Pass resources
Instead of using hardcoded base address implicitly
obtained through <linux/io.h>, pass the physical base
for the QMGR block as a memory resource and remap
it in the driver.

Also pass the two IRQs as resources and obtain them
in the driver.

Use devm_* accessors and simplify the error path in the
process. Drop memory region request as this is done by
the devm_ioremap* functions.
