Currently the mix of genpd_poweron(), genpd_power_on(),
genpd_sync_poweron() and the ->power_on() callback, makes
a bit difficult to follow the path of execution. The similar
applies to the functions dealing with power off.
In a way to improve this understanding, let's do the following renaming:
genpd_power_on() -> _genpd_power_on()
genpd_poweron() -> genpd_power_on()
genpd_sync_poweron() -> genpd_sync_power_on()
genpd_power_off() -> _genpd_power_off()
genpd_poweroff() -> genpd_power_off()
genpd_sync_poweroff() -> genpd_sync_power_off()
genpd_poweroff_unused() -> genpd_power_off_unused()

"swiotlb buffer is full" errors occur after repeated initialisation of a
device - f.e. suspend/resume or ip link set up/down. This is because memory
mapped using dma_map_single() in ravb_ring_format() and ravb_start_xmit()
is not released. Resolve this problem by unmapping descriptors when
freeing rings.

Commit 025bcc1 performed cleanup work on the 'wacom_pl_irq' function, making
it follow the standards used in the rest of the codebase. The change
unintiontionally allowed the function to send input events from reports
that are not marked as being in prox. This can cause problems as the
report values for X, Y, etc. are not guaranteed to be correct. In
particular, occasionally the tablet will send a report with these values
set to zero. If such a report is received it can caus an unexpected jump
in the XY position.
This patch surrounds more of the processing code with a proximity check,
preventing these zeroed reports from overwriting the current state. To
be safe, only the tool type and ABS_MISC events should be reported when
the pen is marked as being out of prox.

In addition to its USB interface, the second-generation Intuos Pro
includes a Bluetooth radio that offers two pairing interfaces: classic
and low-energy. The classic interface functions just like the earlier
Bluetooth-enabled Intuos4 and Graphire4 tablets, appearing as a HID device
that our driver can work with. The low-energy interface is intented to
be used by userspace applications that make use of its paper-to-digital
capabilities.
Despite the USB interface using Wacom's new vendor-defined HID usages,
the Bluetooth interface provides us with useless black-box "blob"
report descriptors like past devices. We thus have to explicitly add
support for the PIDs and reports used.
These devices pack a /lot/ of information into a single Bluetooth
input report. Each report contains up to seven snapshots of the pen
state, four snapshots of the touch state (of five touches each), pad
state, and battery data. Thankfully this isn't too hard for the driver
to report -- it just takes a fair amount of code to extract!

gcc gets confused about the control flow in ktd2692_parse_dt(), causing

We currently don't warn about this, as we raise the warning limit
to 2048 bytes in mainline, but I'd like to lower that limit again
in the future, and this function can easily be changed to be more
efficient and avoid that warning, by making some of its local

The goal of erratum #27704 workaround was to make sure that ASIDs and VMIDs
are unique across all SMMU instances on affected Cavium systems.
Currently, the workaround code partitions ASIDs and VMIDs by increasing
global cavium_smmu_context_count which in turn becomes the base ASID and VMID
value for the given SMMU instance upon the context bank initialization.
For systems with multiple SMMU instances this approach implies the risk
of crossing 8-bit ASID, like for 1-socket CN88xx capable of 4 SMMUv2,
128 context banks each:
SMMU_0 (0-127 ASID RANGE)
SMMU_1 (127-255 ASID RANGE)
SMMU_2 (256-383 ASID RANGE) <--- crossing 8-bit ASID
SMMU_3 (384-511 ASID RANGE) <--- crossing 8-bit ASID
Since now we use 8-bit ASID (SMMU_CBn_TCR2.AS = 0) we effectively misconfigure
ASID[15:8] bits of SMMU_CBn_TTBRm register for SMMU_2/3. Moreover, we still
assume non-zero ASID[15:8] bits upon context invalidation. In the end,
except SMMU_0/1 devices all other devices under other SMMUs will fail on guest
power off/on. Since we try to invalidate TLB with 16-bit ASID but we actually
have 8-bit zero padded 16-bit entry.
This patch adds 16-bit ASID support for stage-1 AArch64 contexts so that
we use ASIDs consistently for all SMMU instances.

It is the time we have the real 16-bit Stream ID user, which is the
ThunderX. Its IO topology uses 1:1 map for Requester ID to Stream ID
translation for each root complex which allows to get full 16-bit
Stream ID. Firmware assigns bus IDs that are greater than 128 (0x80)
to some buses under PEM (external PCIe interface). Eventually SMMU
drops devices on that buses because their Stream ID is out of range:
pci 0006:90:00.0: stream ID 0x9000 out of range for SMMU (0x7fff)
To fix above issue enable the Extended Stream ID optional feature
when available.

With the introduction of the new iommu_{register/get}_instance()
interface in commit e4f10ffe4c9b ("iommu: Make of_iommu_set/get_ops() DT
agnostic") (based on struct fwnode_handle as look-up token, so firmware
agnostic) to register IOMMU instances with the core IOMMU layer there is
no reason to keep the old OF based interface around any longer.
Convert all the IOMMU drivers (and OF IOMMU core code) that rely on the
of_iommu_{set/get}_ops() to the new kernel interface to register/retrieve
IOMMU instances and remove the of_iommu_{set/get}_ops() remaining glue
code in order to complete the interface rework.

smmus that support fewer stream id bits than would fill in a single

smmus that both support the feature and whose first level table can
possibly contain more than a single entry.

The driver reports that it always uses a low-latency mode by returning

Even if this behaviour could not be changed, this may have made some
sense prior to 7a9a65ced11e ("cdc-acm: Fix long standing abuse of
tty->low_latency") which removed the unconditional setting of the
corresponding tty low_latency flag (something which had always been
broken in itself).
Since the driver does not have a low-latency mode, let's drop the flag.

Improvements for Exynos PMU driver for v4.11:
Beside basic function of setting proper configuration for low power modes, the
Exynos PMU (Power Management Unit) driver is also a provider of syscon regmap
for its registers. This regmap is essential to many other drivers wanting to

Exynos pinctrl driver, before getting support for Runtime Power Management,
needs access to this syscon regmap. Let's do it in a DT ABI friendly way.

Apparently each GPIO pad's register are 16 bytes, so multiply the pad_map
by that. The same is done in byt_gpio_reg the only other place where
pad_map is used.

Pad retention control after suspend/resume cycle should be done from pin
controller driver instead of PMU (power management unit) driver to avoid
possible ordering and logical dependencies. Till now it worked fine only
because PMU driver registered its sys_ops after pin controller.
This patch adds infrastructure to handle pad retention during pin control
driver resume.

'enable' parameter has been removed a while ago, so all code for handling
it can be simply removed.

Exynos5433 support has been added in parallel to adding initconst
annotation to most of the init data structures, so add those
annotations also to Exynos5433 structures.

Do not hide pinctrl drivers for Mediatek platforms using
conditionals. Doing so actually leaves the symbols present (but
always disabled) on all other platforms, which is confusing and
inefficient. Better use real dependencies so that the symbols do not
exist at all on platforms where they are not relevant.

This adds support for the pwm_ao_b pin. Unfortunately the registers for
the pwm_ao pins are not documented at all. The source for the pwm_ao_b
pin from this patch is the Khadas VIM GPL kernel source, which sets bit
3 and unsets bits 4 and 31 to enable the PWM LEDs.
