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.

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.

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 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.

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.

These former inlines turn out to be unused in the kernel.
If they are needed in the future, they can be resurrected
by reverting or studying this commit.

These inline functions immediately exploit the static ioremaps
for the queue manager memory region. This does not work with
multiplatform where everything need to be dynamically remapped,
so get rid of these inlines and create new exports for those
used by other drivers.

Drop the memory request region business, this will

Instead of registering everything related to the QMGR
unconditionally in the module_init() call (which will
never work with multiplatform) create a platform device
and probe the QMGR like any other device.
Put the device second in the list of devices added for
the platform so it is there when the dependent network
and crypto drivers probe later on.
This probe() path will not be taken unconditionally on
device tree boots, so remove the DT guard.

This moves the IXP4xx Queue Manager and Network Processing
Engine headers out of the <mack/*> include path as that is
incompatible with multiplatform.
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
The Network Processing Engine and Queue Manager are
versatile firmware components used by several IXP4xx
drivers.
Drivers are relying on getting access to these components
using <mach/*> headers which does not work with
multiplatform. We need to find a better place for the
drivers to live.
Let's first move them to drivers/soc and the start to
refactor a bit by passing resources and moving headers.
This patch introduce static IRQ assignments but that
will be fixed by later patches in this series.

Commit 8df127456f ("soc/tegra: pmc: Enable XUSB partitions on boot")
was added as a workaround to ensure that the XUSB powergates or domains
were turned on early during boot because as this time the Tegra XHCI
driver did not handle the power domains at all. Now that the Tegra XHCI
driver has been updated to properly managed the power domains, the
workaround to enable the XUSB power domain early has been removed. This
also means that we can now move the initialisation of the powergates
into the PMC driver probe. Therefore, move the powergate initialisation
into the PMC driver probe and return any errors detected. To handle any
errors, functions to cleanup and remove any power-domains registered
with the generic power-domain framework have been added.
Finally the initialisation of the 'powergates_available' bitmask is kept
in the PMC early init function to allow the legacy PMC powergate APIs to
be called during early boot for enabling secondary CPUs on 32-bit Tegra
devices.
