112da5cb43 regulator: s2mpa01: Use correct register for buck1 ramp delay
Fix the register for ramp delay of buck1 regulator. Buck1 and buck6
share the field (offset 4) in ramp delay register S2MPA01_REG_RAMP2.

The driver used the same register and field for ramp delay of buck3 and
buck1. This lead to updating of ramp delay of buck3 when setting buck1
and actually the ramp delay of buck1 was never set.

3b9334ac83 mfd: vexpress: Convert custom func API to regmap
Components of the Versatile Express platform (configuration
microcontrollers on motherboard and daughterboards in particular)
talk to each other over a custom configuration bus. They
provide miscellaneous functions (from clock generator control
to energy sensors) which are represented as platform devices
(and Device Tree nodes). The transactions on the bus can
be generated by different "bridges" in the system, some
of which are universal for the whole platform (for the price
of high transfer latencies), others restricted to a subsystem
(but much faster).

Until now drivers for such functions were using custom "func"
API, which is being replaced in this patch by regmap calls.
This required:

* a rework (and move to drivers/bus directory, as suggested
  by Samuel and Arnd) of the config bus core, which is much
  simpler now and uses device model infrastructure (class)
  to keep track of the bridges; non-DT case (soon to be
  retired anyway) is simply covered by a special device
  registration function

* the new config-bus driver also takes over device population,
  so there is no need for special matching table for
  of_platform_populate nor "simple-bus" hack in the arm64
  model dtsi file (relevant bindings documentation has
  been updated); this allows all the vexpress devices
  fit into normal device model, making it possible
  to remove plenty of early inits and other hacks in
  the near future

* adaptation of the syscfg bridge implementation in the
  sysreg driver, again making it much simpler; there is
  a special case of the "energy" function spanning two
  registers, where they should be both defined in the tree
  now, but backward compatibility is maintained in the code

* modification of the relevant drivers:

  * hwmon - just a straight-forward API change
  * power/reset driver - API change
  * regulator - API change plus error handling
    simplification
  * osc clock driver - this one required larger rework
    in order to turn in into a standard platform driver

ed11f1ead5 regulator: tps65090: Make FETs more reliable by adding retries
An issue was discovered with tps65090 where sometimes the FETs
wouldn't actually turn on when requested (they would report
overcurrent).  The most problematic FET was the one used for the LCD
backlight on the Samsung ARM Chromebook (FET1).  Problems were
especially prevalent when the device was plugged in to AC power (when
the backlight voltage was higher).

Mitigate the problem by adding retries on the enables of the FETs,
which works around the problem fairly effectively.

Additionally the GPIO control has two benefits:
 - It is faster than toggling it over I2C bus.
 - It allows disabling the regulator during suspend to RAM; The AP will

Currently the regulator core does not take an additional reference to
the of_node it is passed. This means that the caller must ensure that
the of_node is valid for the duration of the regulator's existance.
It is reasonable for the framework to assume it is passed a valid
of_node but seems onerous for it to assume the caller will keep the node
valid for the life-time of the regulator, especially when
devm_regulator_register is used and there will likely be no code in the
driver called at the point it would be safe to put the of_node.

This patch adds an additional of_node_get when the regulator is
registered and an of_node_put when it is unregistered in the core. This
means individual drivers are free to put their of_node references at the
end of probe letting the regulator core handling it from there. This
simplifies code on the driver side.

3764806440 regulator: core: Add helper to put of_nodes from matches
As of_regulator_match will take an of_node reference to each matched
regulator, it makes sense to provide a helper to put all those
references. This patch does that.

bd0dda744c regulator: core: Add of_node_get to of_regulator_match
Currently, of_regulator_match does not increment the reference count of
the of_nodes it takes new references to. This could cause the node
pointer held to be invalid, by the time it is passed to the regulator
core. This patchs adds an of_node_get when we copy each of_node pointer
into the match structure.

f4fbb3ce34 regulator: s5m8767: Fix carried over ena_gpio assignment
During registration of regulators if external control for regulator was
set in DTS the ena_gpio and ena_gpio_flags fields of regulator_config
were set to proper values.

However the same regulator_config was used in next iterations of loop so
the ena_gpio fields carried over to next regulators.

The issue was not observed as ena_gpio is supported only for Buck9
regulator which is often the last regulator parsed from DTS.
Be sure to clear ena_gpio config fields before registering the
regulator.
