f6b35db072 First set of new device support, cleanups and features for IIO in the 5.9 cycle
Some new devices, but particularly good this time is the core rework coming
 from Alexandru. Some of this has been in Analog's tree a long time, but other
 parts are motivated by closing down common mistakes in new drivers.
 
 Changes since first try at this pull request:
 * Add missed patch to actually remove iio_priv_to_dev and as a result
   also drop a few ingenic patches that need to be updated to take this
   into account.
 * Fix an ordering issue int he pollfunc attach in the core rework.
 
 New device support
 * qcom pmic7 adc
   - New driver using common qcom-vadc library. Some associated cleanups and
     refactors.
 * invensense icm42600
   - New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
     or spi.  These are all 6 axis IMUs with gyro and accelerometers.
     Driver supports buffered modes using the hardware fifo and interpolation
     for accurate timestamps.
 * sensirion scd30
   - New driver for this carbon dioxide sensor including i2c and serial
     interfaces + bindings.
 
 Features
 * ak8975
   - Add reset gpio support.
 * bma400
   - Support SPI.
 * bmc150
   - Document and add support for bmc156b and bmm150b, tidy up _magn endings.
 * bmi160
   - Regulator and mount matrix support.
 * mxc4005
   - Add ID for mxc6655
 * rockchip-saradc
   - Triggered buffer support.
 
 DT bindings
 * qcom spmi-vadc converted to yaml + pmic7 bindings
 * ak8975 tidy up and convert to yaml + add reset-gpio binding
 * ingenic-adc -convert to yaml.
 
 Core rework all carried through by Alexandru Ardelean.
 * Assign parent device in the core rather than every driver. A few devices
   need to provide specific non standard parents, so there is support for
   overriding.
 * Start to take parts of struct iio_dev opaque to the drivers.
   This will be a long term job, but should reduce the number of drivers
   we get that use parts that are currently only 'internal' by documentation.
 * Move attach and detach of pollfunc to the core.  Every triggered buffer
   using driver had to do the same thing, so lets do it in the core.  The
   hard part here was getting all the drivers into canonical form so there
   would be no functional changes in this final patch.  That's taken quite
   a lot of work over last couple of cycles!
 
 Cleanups and minor fixes.
 * docs
   - Improve IIO_CONCENTRATION channel type description in ABI docs.
   - Drop doubled word cases.
   - Http to Https conversion.
 * core
   - Make iio_device_get_drvdata take a const struct iio_dev * avoiding some
     nasty casts.
 * ADCs
   - Drop lots of users of of_match_ptr macro, includes of mod_devicetable.h
     and CONFIG_OF protections.  These prevent use of ACPI PRP0001 with these
     drivers and get coppied into lots of new drivers.
 * ad5380
   - Constify iio_chan_spec_ext_info
 * ad5592r
   - Constify iio_chan_spec_ext_info
   - Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)

   - Make gpio optional as doesn't matter if its there or not.
 * adis16480
   - Use irq types instead of the flags.

240cb8de11 staging: dpaa2-ethsw: setup MAC address of switch netdevices
At probe time, retrieve the MAC addresses of the switch ports using a
firmware call and use that to setup the switch interface net_device
instead of relying entirely on the user to configure a MAC address on
the interface. In case a switch interface is not connected to a MAC,
thus the dpsw_if_get_port_mac_addr() will return all zeroes, generate a
random MAC address and use that.

This new functionality is dependent on a firmware call which is
available only on newer versions, so depending on the running DPSW
object version skip this step.

There are some cases where the switch interface needs to be disabled so
that changes in the configuration can be made. In such cases, we should
check for a running interface (bit __LINK_STATE_START of the netdev)
instead of netif_carrier_ok(). This is because on open() we enable the
switch interface even though the link up has not come out yet.

d1e8c52ab7 staging: comedi: s626: Remove pci-dma-compat wrapper APIs.
The legacy API wrappers in include/linux/pci-dma-compat.h
should go away as it creates unnecessary midlayering
for include/linux/dma-mapping.h APIs, instead use dma-mapping.h
APIs directly.

The patch has been generated with the coccinelle script below

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

a3232e64b4 staging: rtl8712: Use proper format in call to dev_err()
In the call to dev_err(), remove the cast of size_t to int
and change the format string accordingly.

As reported by the kernel test robot, the correct
format string for a size_t argument should be %zu.

2145021c44 Staging: nvec: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

354d6ca9d9 staging: wfx: Get descriptors for GPIOs
The code has the functionality to insert the GPIO lines using
the global GPIO numbers through module parameters.

As we are clearly deprecating the use of global GPIO numbers
look up the GPIO descriptors from the device instead. This
usually falls back to device hardware descriptions using e.g.
device tree or ACPI. This device clearly supports device
tree when used over SPI for example.

For example, this can be supplied in the device tree like so:

  wfx@0x01 {
      compatible = "silabs,wf200";
      reset-gpios = <&gpio0 1>;
      wakeup-gpios = <&gpio0 2>;
  };
