acpi_get_and_request_gpiod() does not take a gpio_lookup_flags argument
specifying that the pins direction should be initialized to a specific
value.

This means that in some cases the pins might be left in input mode, causing
the gpiod_set() calls made to enable the clk / regulator to not work.

One example of this problem is the clk-enable GPIO for the ov01a1s sensor
on a Dell Latitude 9420 being left in input mode causing the clk to
never get enabled.

Explicitly set the direction of the pins to output to fix this.

Pull x86 microcode and IFS updates from Borislav Petkov:
 "The IFS (In-Field Scan) stuff goes through tip because the IFS driver
  uses the same structures and similar functionality as the microcode
  loader and it made sense to route it all through this branch so that
  there are no conflicts.

   - Add support for multiple testing sequences to the Intel In-Field
     Scan driver in order to be able to run multiple different test
     patterns. Rework things and remove the BROKEN dependency so that
     the driver can be enabled (Jithu Joseph)

   - Remove the subsys interface usage in the microcode loader because
     it is not really needed

   - A couple of smaller fixes and cleanups"

Pull regulator updates from Mark Brown:
 "Quite a quiet release for regulator, the diffstat is dominated by the
  I2C migration to probe_new() and the newly added MT6357 driver. We've
  just one framework addition and the rest is all new device support,
  fixes and cleanups.

  The framework addition is an API for requesting all regulators defined
  in DT, this isn't great practice but has reasonable applications when
  there is generic code handling devices on buses where the bus
  specification doesn't include power. The immediate application is MDIO
  but I believe there's others, it's another API that'll need an eye
  keeping on it for undesirable usage.

  Summary:

    - An API for requesting all regulators defined in DT

    - Conversion of lots of drivers to the I2C probe_new() API

    - Support for Mediatek MT6357, Qualcomm PM8550, PMR735a and Richtek

Following by the below discussion, there's the potential UAF issue
between regulator and mfd.
https://lore.kernel.org/all/20221128143601.1698148-1-yangyingliang@huawei.com/

From the analysis of Yingliang

CPU A				|CPU B
mt6370_probe()			|
  devm_mfd_add_devices()	|
				|mt6370_regulator_probe()
				|  regulator_register()
				|    //allocate init_data and add it to devres
				|    regulator_of_get_init_data()
i2c_unregister_device()		|
  device_del()			|
    devres_release_all()	|
      // init_data is freed	|
      release_nodes()		|
				|  // using init_data causes UAF
				|  regulator_register()

It's common to use mfd core to create child device for the regulator.
In order to do the DT lookup for init data, the child that registered
the regulator would pass its parent as the parameter. And this causes
init data resource allocated to its parent, not itself. The issue happen
when parent device is going to release and regulator core is still doing
some operation of init data constraint for the regulator of child device.

To fix it, this patch expand 'regulator_register' API to use the
different devices for init data allocation and DT lookup.
