34b4182ce5 ARM: DRA7: hwmod: Add data for eDMA tpcc, tptc0, tptc1
Add hwmod data for the eDMA blocks:
 - TPCC: Third-party channel controller
 - TPTC0: Third-party transfer controller 0
 - TPTC1: Third-party transfer controller 1

The TPCC's clock gating status follows the status of its clock and
power domain. This means that the hwmod code can not directly control
the TPCC enable/disable status.

1c277cae14 This is the pxa changes for v4.6 cycle.
This is a minor cycle with :
  - cleanup fixes from Arnd, mainly build oriented and sparse type ones
  - dma fixes for requestors above 32 (impacting mainly camera driver)
  - some minor cleanup on pxa3xx device-tree side

c60f9e2980 ARM: dts: DRA7: Add TBCLK for PWMSS
tbclk is used by ehrpwm to generate PWM waveform on DRA7 SoC. Add Linux
clock to control ehrpwm tbclk.
The TRM says, tbclk is derived from SYSCLKOUT. SYSCLKOUT is nothing but
ehrpwm functional clock derived from the gateable interface and
functional clock of PWMSS(l4_root_clk_div).
Refer AM57x TRM SPRUHZ6[1], October 2014, Table 29-4 and Section 29.2.2.1,
Table 29-19 and the NOTE at the end of the table.

9b4a300443 KVM: arm/arm64: timer: Add active state caching
Programming the active state in the (re)distributor can be an
expensive operation so it makes some sense to try and reduce
the number of accesses as much as possible. So far, we
program the active state on each VM entry, but there is some
opportunity to do less.

An obvious solution is to cache the active state in memory,
and only program it in the HW when conditions change. But
because the HW can also change things under our feet (the active
state can transition from 1 to 0 when the guest does an EOI),
some precautions have to be taken, which amount to only caching
an "inactive" state, and always programing it otherwise.

With this in place, we observe a reduction of around 700 cycles
on a 2GHz GICv2 platform for a NULL hypercall.

bb0c70bcca arm64: KVM: Add a new vcpu device control group for PMUv3
To configure the virtual PMUv3 overflow interrupt number, we use the
vcpu kvm_device ioctl, encapsulating the KVM_ARM_VCPU_PMU_V3_IRQ
attribute within the KVM_ARM_VCPU_PMU_V3_CTRL group.

After configuring the PMUv3, call the vcpu ioctl with attribute
KVM_ARM_VCPU_PMU_V3_INIT to initialize the PMUv3.

assign a overflow handler. Then when the perf event overflows, set the
corresponding bit of guest PMOVSSET register. If this counter is enabled

changed, inject the interrupt with corresponding level. On VM exit, sync

57c841f131 arm/arm64: KVM: Handle out-of-RAM cache maintenance as a NOP
So far, our handling of cache maintenance by VA has been pretty
simple: Either the access is in the guest RAM and generates a S2
fault, which results in the page being mapped RW, or we go down
the io_mem_abort() path, and nuke the guest.

The first one is fine, but the second one is extremely weird.
Treating the CM as an I/O is wrong, and nothing in the ARM ARM
indicates that we should generate a fault for something that
cannot end-up in the cache anyway (even if the guest maps it,
it will keep on faulting at stage-2 for emulation).

So let's just skip this instruction, and let the guest get away
with it.

4cad67fca3 arm/arm64: KVM: Fix ioctl error handling
Calling return copy_to_user(...) in an ioctl will not
do the right thing if there's a pagefault:
copy_to_user returns the number of bytes not copied
in this case.

Fix up kvm to do
	return copy_to_user(...)) ?  -EFAULT : 0;

everywhere.

Downstream packages like Debian flash-kernel use
/proc/device-tree/model
to determine which dtb file to install.

Hence each dts in the Linux kernel should provide a unique model
identifier.

Commit 8536239e37 ("ARM: dts: Restructure imx6qdl-wandboard.dtsi for new
rev C1 board.")' created new files imx6dl-wandboard-revb1.dts and
imx6q-wandboard-revb1.dts but used the same model identifier as in
imx6dl-wandboard.dts and imx6q-wandboard.dts.

This patch provides unique model identifiers for revision B1 of
the Wandboard Dual and Wandbaord Quad.

The patch leaves imx6dl-wandboard.dts and imx6q-wandboard.dts unchanged
because it is not foreseeable if the same dts will valid for future
board revisions or not. Furthermore we should avoid unnecessary
changes.

4a4d45c78d ARM: dts: vf610: relicense vf???.dtsi under GPLv2/X11
GPLv2-only devicetrees make reuse difficult for software components
licensed under a different license.

The consensus is that a GPL/X11 dual-license should allow all necessary
uses, so relicense the vfxxx.dtsi, vf500.dtsi and vf610.dtsi files to
this combination.

PCIe reset signals are active low, and our GPIO for this is directly
connected to the PCIe reset.  However, as the PCIe driver was not using
the flag, the specification of '0' flags (which means active high) had

All the generic L2 cache handling code is encapsulated by a
check if the L2 cache is enabled. If it's enabled already, the code
is skipped. The write to the L2-Cache controller from non-secure
world causes an imprecise external abort. This is needed in
scenarios where one of the cores runs an other OS, e.g. an RTOS.

For the i.MX6 specific L2 cache handling we missed this check.

b4042a4c01 ARM: imx: select ARM_CPU_SUSPEND only for imx6
i.MX only needs to select ARM_CPU_SUSPEND manually for the
very specific case that CONFIG_PM_SLEEP is disabled and imx6
is used with CONFIG_PM enabled for runtime PM.

If we are building a kernel only for CPUs that are not using
the cpu_suspend() helper, we otherwise get a harmless
build warning:

warning: (ARCH_MXC && SOC_IMX23 && SOC_IMX28 && ARCH_PXA && MACH_MVEBU_V7 && ARCH_OMAP3 && ARCH_OMAP4 && SOC_OMAP5 && SOC_AM33XX && SOC_DRA7XX && ARCH_EXYNOS3 && ARCH_EXYNOS4 && EXYNOS5420_MCPM &&
EXYNOS_CPU_SUSPEND && ARCH_VEXPRESS_TC2_PM && ARM_BIG_LITTLE_CPUIDLE && ARM_HIGHBANK_CPUIDLE && QCOM_PM) selects ARM_CPU_SUSPEND which has unmet direct dependencies (ARCH_SUSPEND_POSSIBLE)

This moves the option to the SOC_IMX6 option that actually
requires it, in effect reverting commit f36b594f37 ("ARM:
mach-imx: Select ARM_CPU_SUSPEND at ARCH_MXC level") that was
meant as a cleanup and unintentionally caused this warning.

ef2b1d777d ARM: prima2: always enable reset controller
The atlas7 clock controller driver registers a reset controller
for itself, which causes a link error when the subsystem is
disabled:

drivers/built-in.o: In function `atlas7_clk_init':
drivers/clk/sirf/clk-atlas7.c:1681: undefined reference to `reset_controller_register'

As the clk driver does not have a Kconfig symbol for itself
but it always built-in when the platform is enabled, we have
to ensure that the reset controller subsystem is also built-in
in this case.

The core clock does not depend on corediv, so enabling corediv
based on the clock is not really correct.  Move the corediv
config option from the clock driver Kconfig to the mvebu Kconfig
so that it can be enabled by the MACH option instead.

This also enables corediv on Armada 375 and 38X, which was
previously missing.

097872945e dts: sun8i-h3: Add APB0 related clocks and resets
APB0 is bearly mentioned in H3 User Manual and it is only setup in the
Allwinners kernel dump for CIR. I have verified experimentally that the
gate for R_PIO exists and works, though. There are probably other gates
there but I don't know their order right now and I don't have access to
their peripherals on my board to test them.

After some experiments and reviewing how this is organized on other
sunxi SoCs, I couldn't actually find any way to disable clocks for R_PIO
and they are working properly without doing anything so I assume they
are connected straight to the 24Mhz oscillator for now.
