Add support for AD4111/AD4112/AD4114/AD4115/AD4116.
The AD411X family encompasses a series of low power, low noise, 24-bit,
sigma-delta analog-to-digital converters that offer a versatile range of
specifications.
This family of ADCs integrates an analog front end suitable for processing
both fully differential and single-ended, bipolar voltage inputs
addressing a wide array of industrial and instrumentation requirements.
- All ADCs have inputs with a precision voltage divider with a division
ratio of 10.
- AD4116 has 5 low level inputs without a voltage divider.
- AD4111 and AD4112 support current inputs (0 mA to 20 mA) using a 50ohm
shunt resistor.

The ADCs supported by this driver feature a sequencer that read in a
loop all the enabled chanels. When setting the individual sampling
frequency for each channel and enabling multiple channels, the effective
of each channel will be lower than the actual set value. Document this
behaviour in a comment.

The previous driver never worked, and never got even compiled because

This is a full (or nearly full) refactoring of the MediaTek DVFSRC
controlled Regulators driver, retaining support for the MT6873, MT8183
and MT8192 SoC, and adding MT8195.
As part of the refactoring, this driver is now probed using its own

and gets probed as a subnode of that.

1394 OHCI hardware triggers PCI interrupts to notify any events to
software. Current driver for the hardware is programmed by the typical
way to utilize top- and bottom- halves, thus it has a timing gap to handle
the notification in softIRQ (tasklet).
This commit adds a tracepoint event for the hardIRQ event. The comparison
of the tracepoint event to tracepoints events in firewire subsystem is

Commit b6846826982b ("thermal: gov_step_wise: Restore passive polling
management") attempted to fix a Step-Wise thermal governor issue
introduced by commit 042a3d80f118 ("thermal: core: Move passive polling
management to the core"), which caused the governor to leave cooling
devices in high states, by partially reverting that commit.
However, this turns out to be insufficient on some systems due to
interactions between the governor code restored by commit b6846826982b
and the passive polling management in the thermal core.
For this reason, revert commit b6846826982b and make the governor set
the target cooling device state to the "lower" one as soon as the zone
temperature falls below the threshold of the trip point corresponding
to the given thermal instance, which means that thermal mitigation is
not necessary any more.
Before this change the "lower" cooling device state would be reached in
steps through the passive polling mechanism which was questionable for
three reasons: (1) cooling device were kept in high states when that was
not necessary (and it could adversely impact performance), (2) it only
worked for thermal zones with nonzero passive_delay_jiffies value, and
(3) passive polling belongs to the core and should not be hijacked by
governors for their internal purposes.

The IOMMU IP in the Allwinner H616 SoC is *almost* compatible to the H6,
but uses a different reset value for the bypass register, and adds some
more registers.
While a driver *can* be written to support both variants (which we in
fact do), the hardware itself is not fully compatible, so we require a
separate compatible string.
Add the new compatible string to the list, but without changing the
behaviour, since the driver already supports both variants.

The Allwinner IOMMU is a strict 32-bit device, with its input addresses,
the page table root pointer as well as both level's page tables and also
the target addresses all required to be below 4GB.
The Allwinner H6 SoC only supports 32-bit worth of physical addresses
anyway, so this isn't a problem so far, but the H616 and later SoCs extend
the PA space beyond 32 bit to accommodate more DRAM.
To make sure we stay within the 32-bit PA range required by the IOMMU,
force the memory for the page tables to come from below 4GB. by using
allocations with the DMA32 flag.
Also reject any attempt to map target addresses beyond 4GB, and print a
warning to give users a hint while this fails.

The Allwinner H6 IOMMU has a bypass register, which allows to circumvent
the page tables for each possible master. The reset value for this
register is 0, which disables the bypass.
The Allwinner H616 IOMMU resets this register to 0x7f, which activates
the bypass for all masters, which is not what we want.
Always clear this register to 0, to enforce the usage of page tables,
and make this driver compatible with the H616 in this respect.

The in-parameter "opp_table" isn't needed by _set_opp_level(). Let's
therefore drop it.
