- 16 fast GPIOs individually configurable in input/output
- 8 alternate GPIOs individually configurable in input/output when other
STMFX functions are not used
- Main MCU IDD measurement

NFP shift instruction has something special. If shift direction is left
then shift amount of 1 to 31 is specified as 32 minus the amount to shift.
But no need to do this for indirect shift which has shift amount be 0. Even
after we do this subtraction, shift amount 0 will be turned into 32 which
will eventually be encoded the same as 0 because only low 5 bits are
encoded, but shift amount be 32 will fail the FIELD_PREP check done later
on shift mask (0x1f), due to 32 is out of mask range. Such error has been
observed when compiling nfp/bpf/jit.c using gcc 8.3 + O3.
This issue has started when indirect shift support added after which the
incoming shift amount to __emit_shf could be 0, therefore it is at that
time shift amount adjustment inside __emit_shf should have been tightened.

Pull clk framework updates from Stephen Boyd:
"We have a couple new features and changes in the core clk framework
this time around because we've finally gotten around to fixing some
long standing issues. There's still work to do though, so this pull
request is largely laying down the foundation for all the driver
changes to come in the next merge window.
The first problem we're alleviating is how parents of clks are
specified. With the new method, we should see lots of drivers migrate
away from the current design of string comparisons on the entire clk
tree to a more direct method where they can use clk_hw pointers or
more localized names specified in DT or via clkdev. This should reduce
our reliance on string comparisons for all the topology description
logic that we've been using for years and hopefully speed some things
up while avoiding problems we have with generating clk names.
Beyond that we also got rid of the CLK_IS_BASIC flag because it wasn't
really helping anyone and we introduced big-endian versions of the
basic clk types so that we can get rid of clk_{readl,writel}(). Both
of these are things that driver developers have tried to use over the
years that I typically bat away during code reviews because they're
not useful. It's great to see these two things go away so maintainers
can save time not worrying about these things.
On the driver side we got the usual collection of new SoC support and
non-critical fixes and updates to existing code. The big topics that
stand out are the new driver support for Mediatek MT8183 and MT8516
SoCs, Amlogic Meson8b and G12a SoCs, and the SiFive FU540 SoC. The
other patches in the driver pile are mostly fixes for things that are
being used for the first time or additions for clks that couldn't be
tested before because there wasn't a consumer driver that exercised
them. Details are below and also in the sub-maintainer tags.
Core:
- Remove clk_readl() and introduce BE versions of basic clk types
- Rewrite how clk parents can be specified to allow DT/clkdev lookups
- Removal of the CLK_IS_BASIC clk flag
- Framework documentation updates and fixes
New Drivers:
- Support for STM32F769

- Qualcomm QCS404 Turing clk support
- Mediatek MT8183 clock support
- Mediatek MT8516 clock support

Pull RTC updates from Alexandre Belloni:
"A huge series from me this cycle. I went through many drivers to set
the date and time range supported by the RTC which helps solving HW
limitation when the time comes (as early as next year for some). This
time, I focused on drivers using .set_mms and .set_mmss64, allowing me
to remove those callbacks. About a third of the patches got reviews, I
actually own the RTCs and I tested another third and the remaining one
are unlikely to cause any issues.
Other than that, a single new driver and the usual fixes here and there.
Summary:
Subsystem:
- set_mmss and set_mmss64 rtc_ops removal
- Fix timestamp value for RTC_TIMESTAMP_BEGIN_1900
- Use SPDX identifier for the core
- validate upper bound of tm->tm_year

- Aspeed BMC SoC RTC

- abx80x: use rtc_add_group
- ds3232: nvram support
- pcf85063: add alarm, nvram, offset correction and microcrystal

Previously pciehp debug messages were enabled by the pciehp_debug module
parameter, e.g., by booting with this kernel command line option:
pciehp.pciehp_debug=1
Convert this mechanism to use the generic dynamic debug (dyndbg) feature.
After this commit, pciehp debug messages are enabled by building the kernel
with CONFIG_DYNAMIC_DEBUG=y and booting with this command line option:
dyndbg="file pciehp* +p"
The dyndbg facility is much more flexible: messages can be enabled at boot-
or run-time based on the file name, function name, line number, message
test, etc. See Documentation/admin-guide/dynamic-debug-howto.rst for more
details.

review on the list.
Summary:
- Driver fixes for hns, hfi1, nes, rxe, i40iw, mlx5, cxgb4,
vmw_pvrdma
- Many patches from MatthewW converting radix tree and IDR users to
use xarray
- Introduction of tracepoints to the MAD layer
- Build large SGLs at the start for DMA mapping and get the driver to
split them
- Generally clean SGL handling code throughout the subsystem
- Support for restricting RDMA devices to net namespaces for
containers
- Progress to remove object allocation boilerplate code from drivers
- Change in how the mlx5 driver shows representor ports linked to VFs
- mlx5 uapi feature to access the on chip SW ICM memory
- Add a new driver for 'EFA'. This is HW that supports user space
packet processing through QPs in Amazon's cloud"

For the PWM controller in the Meson G12A SoC, the EE domain and AO domain
have different clock sources. This patch tries to describe them in the
DT compatible data. The two AO PWM controller has different clock source,
but the first AO controller (A & B) can reuse the AXG parents name.

A call to ->request() is always paired by a call to ->free() before a
given device is disposed. So the simplification that usually is possible
when using devm_*() functions cannot be used here. So use plain
kzalloc() and kfree() for improved runtime behaviour and reduced memory
footprint.

After a PWM is disposed by its user the per chip data becomes invalid.
Clear the data in common code instead of the device drivers to get

i.MX7ULP has TPM(Low Power Timer/Pulse Width Modulation Module) inside,
it can support multiple PWM channels, all the channels share same
counter and period setting, but each channel can configure its duty and
polarity independently.
There are several TPM modules in i.MX7ULP, the number of channels in TPM
modules are different, it can be read from each TPM module's PARAM
register.

Holding the spin-lock for all of the code in meson_pwm_apply() can
result in a "BUG: scheduling while atomic". This can happen because
clk_get_rate() (which is called from meson_pwm_calc()) may sleep.
Only hold the spin-lock when modifying registers to solve this.
The reason why we need a spin-lock in the driver is because the
REG_MISC_AB register is shared between the two channels provided by one
PWM controller. The only functions where REG_MISC_AB is modified are
meson_pwm_enable() and meson_pwm_disable() so the register reads/writes
in there need to be protected by the spin-lock.
The original code also used the spin-lock to protect the values in
struct meson_pwm_channel. This could be necessary if two consumers can
use the same PWM channel. However, PWM core doesn't allow this so we
don't need to protect the values in struct meson_pwm_channel with a
lock.

There is an abnormally low about 20ms,when setting duty repeatedly.
Because setting the duty will disable PWM and then enable. Delete

The pre-divider allows configuring longer PWM periods compared to using
the input clock directly. The pre-divider is 7 bit wide, meaning it's
maximum value is 128 (the register value is off-by-one: 0x7f or 127).
Change the loop to also allow for the maximum possible value to be
considered valid.

Replace dev_printk(KERN_DEBUG) with dev_info(), etc to be more consistent
with other logging and avoid checkpatch warnings.
The KERN_DEBUG messages could be converted to dev_dbg(), but that depends
on CONFIG_DYNAMIC_DEBUG and DEBUG, and we want most of these messages to
*always* be in the dmesg log.
