The Pine64 H64 board uses an AXP806 PMIC in I2C and self-working mode.
The H64 SoC does not have the usual RSB controller.
This patch adds AXP806 to the list of devices supported in I2C mode.
In theory, all RSB-based PMICs can also be used in I2C mode.

The AXP806 can operate in a standalone "self-working" mode, in which it
is also responsible for power control of the overall system. This mode
is similar to the master mode, but the EN/PWRON pin functions as a power
button, instead of a level-triggered enable switch.
This patch adds code checking for the new "x-powers,self-working-mode"
property, and a separate mfd_cell list that includes the power button
(PEK) sub-device.

The USB completion callback does not disable interrupts while acquiring
the lock. We want to remove the local_irq_disable() invocation from
__usb_hcd_giveback_urb() and therefore it is required for the callback
handler to disable the interrupts while acquiring the lock.
The callback may be invoked either in IRQ or BH context depending on the
USB host controller.
Use the _irqsave() variant of the locking primitives.

Some Arizona CODECs have a small timing window where they will
NAK an I2C transaction if it happens before the boot done bit is
set. This can cause the read of the register containing the boot
done bit to fail until it is set. Since regmap_read_poll_timeout
will abort polling if a read fails it can't be reliably used to
poll the boot done bit over I2C.
Do a partial revert of ef84f885e0 ("mfd: arizona: Refactor
arizona_poll_reg"), removing the regmap_read_poll_timeout but
leaving the refactoring to make the arizona_poll_reg take more
sensible arguments.

There's been quite a bit of work from Linus Walleij on converting from
specfying GPIOs by numbers to descriptors. Sadly the testing turned out
to be less good than we had hoped and so a lot of this had to be
reverted.
We also have the start of updates to use coupled regulators from Maciej

Core changes:
- We have killed off VLA from the core library and all drivers.
The background should be clear for everyone at this point:
https://lwn.net/Articles/749064/
Also I just don't like VLA's, kernel developers hate it when
compilers do things behind their back. It's as simple as that.
I'm sorry that they even slipped in to begin with.
Kudos to Laura Abbott for exorcising them.
- Support GPIO hogs in machines/board files.
New drivers and chip support:
- R-Car r8a77470 (RZ/G1C)
- R-Car r8a77965 (M3-N)
- R-Car r8a77990 (E3)
- PCA953x driver improvements to accomodate more variants.
Improvements and new features:
- Support one interrupt per line on port A in the DesignWare
dwapb driver.
Misc:
- Random cleanups, right header files in the drivers, some
size optimizations etc.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.18 development cycle.
Core changes:
- We have killed off VLA from the core library and all drivers.
The background should be clear for everyone at this point:
https://lwn.net/Articles/749064/
Also I just don't like VLA's, kernel developers hate it when
compilers do things behind their back. It's as simple as that.
I'm sorry that they even slipped in to begin with. Kudos to Laura
Abbott for exorcising them.
- Support GPIO hogs in machines/board files.
New drivers and chip support:
- R-Car r8a77470 (RZ/G1C)
- R-Car r8a77965 (M3-N)
- R-Car r8a77990 (E3)
- PCA953x driver improvements to accomodate more variants.
Improvements and new features:
- Support one interrupt per line on port A in the DesignWare dwapb
driver.
Misc:
- Random cleanups, right header files in the drivers, some size
optimizations etc"

If the feature query fails during this driver's probe, we memset the

Intel Cannon Lake PCH has much higher 216 MHz input clock to LPSS I2C
than Sunrisepoint which uses 120 MHz. Preliminary information was that
both share the same clock rate but actual silicon implements elevated
rate for better support for 3.4 MHz high-speed I2C.
This incorrect input clock rate results too high I2C bus clock in case
ACPI doesn't provide tuned I2C timing parameters since I2C host
controller driver calculates them from input clock rate.
Fix this by using the correct rate. We still share the same 230 ns SDA
hold time value than Sunrisepoint.

The cros_ec_i2c driver is still active after it had suspended or before it
resumes. Besides that, it also tried to transfer data even after the I2C
host had been suspended. This will lead the system to crash.
During the test, we also observe that the EC needs to be resumed earlier
due to some status polling from the EC FW (e.g. battery status). So we
move the PM ops to late stage to make it work normally.

Commit 001dde9400 ("mfd: cros ec: spi: Fix "in progress" error
signaling") pointed out some bad code, but its analysis and conclusion
was not 100% correct.
It *is* correct that we should not propagate result==EC_RES_IN_PROGRESS
for transport errors, because this has a special meaning -- that we
should follow up with EC_CMD_GET_COMMS_STATUS until the EC is no longer
busy. This is definitely the wrong thing for many commands, because
among other problems, EC_CMD_GET_COMMS_STATUS doesn't actually retrieve
any RX data from the EC, so commands that expected some data back will
instead start processing junk.
For such commands, the right answer is to either propagate the error
(and return that error to the caller) or resend the original command
(*not* EC_CMD_GET_COMMS_STATUS).
Unfortunately, commit 001dde9400 forgets a crucial point: that for
some long-running operations, the EC physically cannot respond to
commands any more. For example, with EC_CMD_FLASH_ERASE, the EC may be
re-flashing its own code regions, so it can't respond to SPI interrupts.
Instead, the EC prepares us ahead of time for being busy for a "long"
time, and fills its hardware buffer with EC_SPI_PAST_END. Thus, we
expect to see several "transport" errors (or, messages filled with
EC_SPI_PAST_END). So we should really translate that to a retryable
error (-EAGAIN) and continue sending EC_CMD_GET_COMMS_STATUS until we
get a ready status.
IOW, it is actually important to treat some of these "junk" values as
retryable errors.
Together with commit 001dde9400, this resolves bugs like the
following:
1. EC_CMD_FLASH_ERASE now works again (with commit 001dde9400, we
would abort the first time we saw EC_SPI_PAST_END)
2. Before commit 001dde9400, transport errors (e.g.,
EC_SPI_RX_BAD_DATA) seen in other commands (e.g.,
EC_CMD_RTC_GET_VALUE) used to yield junk data in the RX buffer; they
will now yield -EAGAIN return values, and tools like 'hwclock' will
simply fail instead of retrieving and re-programming undefined time
values

Instead of passing a global GPIO number for the enable GPIO, pass
a descriptor looked up from the device tree node or the board file
decriptor table for the regulator.
There is a single board file passing the GPIOs for LDO1 and LDO2
through platform data, so augment this to pass descriptors
associated with the i2c device as well.
The special GPIO enable DT property for the enable GPIO is
nonstandard but this was accomodated in

The DesignWare GPIO IP can be configured for either 1 interrupt or 1
per GPIO in port A, but the driver currently only supports 1 interrupt.
See the DesignWare DW_apb_gpio Databook description of the
'GPIO_INTR_IO' parameter.
This change allows the driver to work with up to 32 interrupts, it will
get as many interrupts as specified in the DT 'interrupts' property.
It doesn't do anything clever with the different interrupts, it just calls
the same handler used for single interrupt hardware.

When looking up the clock we must use the client->dev as device since that
is the one which is probed via DT.

When AXP806 support was added, POK was incorrectly expanded to PWROK.
However, the datasheet lists them as POK[LSNP], which is the same as
on the AXP288. Furthermore, the registers associated with POK functions
are the same as the PEK on the other AXP PMICs. This suggests that
"POK" means "Power On Key", much like "PEK" means "Power Enable Key",
instead of "Power OK".
This patch changes the "PWROK" prefix to "POK" for these interrupts.

Previously we were open coding the interrupts for the various mfd
cells. This made the code somewhat long due to pretty-formatting.
This patch convert those into one-line declarations with DEFINE_RES_IRQ,
making the code shorter and easier to read.

Replace multi-line entries in the regmap_range arrays with single
line macros: regmap_reg_range(). This will leave the static structure
array entries for regmap_range unaltered. It will significantly reduce
the line count in the DA9062/61 core file.

Now GPIOD has support for both pdata systems and for non-standard DT
bindings the Arizona reset GPIO can be converted to use it. Worth
noting gpiod_set_raw_value_cansleep is used to match the behaviour
of the old GPIOs. This is because the part is fairly widely used and
it is unknown how many DTs are correctly setting active low through
device tree, so to avoid breaking any existing users it is best to
match the previous behaviour.

There are some global registers in Spreadtrum sc27xx PMICs, which will
be accessed by other drivers. So this patch adds one syscon cell to
help to access the PMIC's global registers.
