Declare regmap_irq_chip structures as const as they are only stored
in the regmap_irq_chip field of a rk808 structure. This field is of
type const, so regmap_irq_chip structures having this property can be
made const too.

Many Motorola phones like droid 4 are using a custom PMIC called CPCAP
or 6556002. We can support it's core features quite easily with regmap_spi
and regmap_irq.
The children of cpcap, such as regulators, ADC and USB, can be just regular
device drivers and defined in the dts file. They get probed as we call
of_platform_populate() at the end of our probe, and then the children
can just call dev_get_regmap(dev.parent, NULL) to get the regmap.

The I2C core always reports a MODALIAS of the form i2c:<foo> even if the
device was registered via OF, this means that exporting the OF device ID
table device aliases in the module is not needed. But in order to change
how the core reports modaliases to user-space, it's better to export it.
Before this patch:
$ modinfo drivers/mfd/tps65912-i2c.ko | grep alias
alias: i2c:tps65912

If a driver is only used in DT platforms, there's no need to get the
i2c_device_id as an argument of the probe function. Since this data
can be get from the matching of_device_id.
There's a temporary .probe_new field in struct i2c_driver that can be
used as probe callback for the case when i2c_device_id won't be used.

Use the generic helper to get the matched of_device_id .data, instead of
open coding it.
The driver was checking if matching the OF node with the driver's OF table
was failing, but this doesn't make too much sense since this can't happen
in practice. The fact the probe function was called, means OF registered a
device with a valid compatible string so a of_device_get_match_data() call
will always succeed. So just remove this unneeded check.

In the current boot, clients making use of the AB8500 sysctrl
may be probed before the ab8500-sysctrl driver. This gives them
-EINVAL, but should rather give -EPROBE_DEFER.
Before this, the abx500 clock driver didn't probe properly,
and as a result the codec driver in turn using the clocks did
not probe properly. After this patch, everything probes
properly.
Also add OF compatible-string probing. This driver is all
device tree, so let's just make a drive-by-fix of that as
well.

The AXP806 supports either master/standalone or slave mode.
Slave mode allows sharing the serial bus, even with multiple
AXP806 which all have the same hardware address.
This is done with extra "serial interface address extension",
or AXP806_BUS_ADDR_EXT, and "register address extension", or
AXP806_REG_ADDR_EXT, registers. The former is read-only, with
1 bit customizable at the factory, and 1 bit depending on the
state of an external pin. The latter is writable. Only when
the these device addressing bits (in the upper 4 bits of the
registers) match, will the device respond to operations on
its other registers.
The AXP806_REG_ADDR_EXT was previously configured by Allwinner's
bootloader. Work on U-boot SPL support now allows us to switch
to mainline U-boot, which doesn't do this for us. There might
be other bare minimum bootloaders out there which don't to this
either. It's best to handle this in the kernel.
This patch sets AXP806_REG_ADDR_EXT to 0x10, which is what we
know to be the proper value for a standard AXP806 in slave mode.
Afterwards it will reinitialize the regmap cache, to purge any
invalid stale values.

The R in PEK_DBR stands for rising, so it should be mapped to
AXP288_IRQ_POKP where the last P stands for positive edge.
Likewise PEK_DBF should be mapped to the falling edge, aka the

The axp288 has the following irqs 2 times: VBUS_FALL, VBUS_RISE,
VBUS_OV. On boot / reset the enable flags for both the normal and alt
version of these irqs is set.
Since we were only listing the normal version in the axp288 regmap_irq
struct, we were never disabling the alt versions of these irqs.
Add the alt versions to the axp288 regmap_irq struct, so that these
get properly disabled.
Together with the other axp288 fixes in this series, this fixes the axp288

The interrupt line of the entire family of axp2xx pmics is active-low,
for devicetree enumerated irqs, this is dealt with in the devicetree.
ACPI irq resources have a flag field for this too, I tried using this
on my CUBE iwork8 Air tablet, but it does not contain the right data.
The dstd shows the irq listed as either ActiveLow or ActiveHigh,
depending on the OSID variable, which seems to be set by the
"OS IMAGE ID" in the BIOS/EFI setup screen.
Since the acpi-resource info is no good, simply pass in IRQF_TRIGGER_LOW
on the axp288.

Timers IPs can be used to generate triggers for other IPs like
DAC or ADC.
Each trigger may result of timer internals signals like counter enable,
reset or edge, this configuration could be done through "master_mode"
device attribute.
Since triggers could be used by DAC or ADC their names are defined
in include/ nux/iio/timer/stm32-timer-trigger.h and is_stm32_iio_timer_trigger
function could be used to check if the trigger is valid or not.
"trgo" trigger have a "sampling_frequency" attribute which allow to configure
timer sampling frequency.
version 8:
- change kernel version from 4.10 to 4.11 in ABI documentation
version 7:
- remove all iio_device related code
- move driver into trigger directory
version 5:
- simplify tables of triggers
- only create an IIO device when needed
version 4:
- get triggers configuration from "reg" in DT
- add tables of triggers
- sampling frequency is enable/disable when writing in trigger
sampling_frequency attribute
- no more use of interruptions
version 3:
- change compatible to "st,stm32-timer-trigger"
- fix attributes access right
- use string instead of int for master_mode and slave_mode
- document device attributes in sysfs-bus-iio-timer-stm32
version 2:
- keep only one compatible
- use st,input-triggers-names and st,output-triggers-names
to know which triggers are accepted and/or create by the device

When the axp288_faul_gauge driver was originally merged, it was
merged with a dependency on some other driver providing platform
data for it.
However the battery-data-framework which should provide that data
never got merged, resulting in x86 tablets / laptops with an axp288
having no working battery monitor, as before this commit the driver
would simply return -ENODEV if there is no platform data.
This commit removes the dependency on the platform_data instead
checking that the firmware has initialized the fuel-gauge and
reading the info back from the pmic.
What is missing from the read-back info is the table to map raw adc
values to temperature, so this commit drops the temperature and
temperature limits properties. The min voltage, charge design and
model name info is also missing. Note that none of these are really
important for userspace to have.
All other functionality is preserved and actually made available
by this commit.

The timer type simplifications caused a new gcc warning:
drivers/base/power/domain.c: In function ‘genpd_runtime_suspend’:
drivers/base/power/domain.c:562:14: warning: ‘time_start’ may be used uninitialized in this function [-Wmaybe-uninitialized]
elapsed_ns = ktime_to_ns(ktime_sub(ktime_get(), time_start));
despite the actual use of "time_start" not having changed in any way.
It appears that simply changing the type of ktime_t from a union to a
plain scalar type made gcc check the use.
The variable wasn't actually used uninitialized, but gcc apparently
failed to notice that the conditional around the use was exactly the
same as the conditional around the initialization of that variable.
Add an unnecessary initialization just to shut up the compiler.

ktime is a union because the initial implementation stored the time in
scalar nanoseconds on 64 bit machine and in a endianess optimized timespec
variant for 32bit machines. The Y2038 cleanup removed the timespec variant

become completely pointless.

Even if both drivers are compiled in only one instance can run on a given
system depending on the available GIC version.
So having seperate hotplug states for them is pointless.

When the state names got added a script was used to add the extra argument
to the calls. The script basically converted the state constant to a
string, but the cleanup to convert these strings into meaningful ones did
not happen.
Replace all the useless strings with 'subsys/xxx/yyy:state' strings which
are used in all the other places already.

This is the minimal fixup so we can remove the hotplug notifier mess
completely.
The real rework of this driver to use work queues is still stuck in
review/testing on the SCSI mailing list.
