staging: mt7621-pci: avoid to poweroff the phy for slot one

Phy for slot 0 and 1 is shared and handled properly in slot 0.
If there is only one port in use,(slot 0) we shall not call the
'phy_power_off' function with an invalid slot because kernel
will crash with an unaligned access fault like the following:

This soc has two phy's for the pcie one of them using just a different
register for settig it up but sharing all the rest of the config. Until

tree using the 'phy-cells' node property to discriminate an index and
setting up a complete phy for the dual port index. This sometimes worked
properly but reconfiguring the same registers twice presents sometimes
some unstable pcie links and the ports was not properly being detected.
The problems only appears on hard resets and soft resets was properly
working. Instead of having this schema just set two phy's in the device
ree and use the 'phy-cells' property to say if the port has or not a dual
port. Doing this configuration and set up becomes easier, LOC is decreased
and the behaviour also gets deterministic with properly and stable pcie
links in both hard and soft resets.

Merge tag 'iio-5.7a' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First set of new IIO device support, fatures and cleanups for the 5.7 cycle

Includes changes for the counter subsystem

Core Feature
* Explicitly handle sysfs values in dB, including correctly handling the
  needed postfix dB.
* Add a TODO to suggest suitable activities for new contributors to IIO now
  the vast majority of drivers are out of staging (and the remaining ones
  there are 'hard'). Also update the TODO in staging to remove stale entries.

Staging graduations
* ad7192 ADC.

New device support
* ad5770r
  - New driver for this 6 channel DAC including DT bindings.
* ad8366
  - Add supprot for the hmc1119 attenuator.
* al3010
  - New driver supporting this Dyna-image light sensors.
  - Power management and DT bindings added in additional patches.
* atlas-sensor
  - Add support for atlas DO-SM device.  Reads disolved oxygen in a solution.
* gpap002x00f
  - New driver and bindings to support the GP2AP002A00F and GP2AP002S00F light
    and proximity sensors. There is some limited existing support in
    input.  The intent is to drop this driver once IIO driver is in place.
* hmc425a
  - New driver for this attenuator.
* icp10100
  - New driver for this presure sensor.
* ltc2632
  - Add support for the ltc2636 8 channel DAC. Includes bindings and some
    tidying up of the driver.
* inv_mpu6050
  - Support IAM20680, ICM20609, ICM20689 and ICM20690.
    Includes related tidy up and rework of low pass filter bandwidth
    handling to give suitable values for all chips.

Binding conversions to yaml or missing bindings docs.
* atlas-sensor, including consolidation of previous 3 separate docs into 1.
* ad7923, previously no doc.
* max1363, split into max1238 and max1363 to simplify yaml.
* stm32-adc

Features
* (counter) 104-quad-8
  - Support a filter clock prescaler.
  - Support reporting of encoder cable status.
* ad7124
  - Low pass filter support.
  - Debugfs interface to access registers directly.
* ad8366
  - Support control of hardware gain.
* inv_mpu6050
  - Runtime pm with autosuspend.
* npcm adc
  - Add reset support. This is a breaking change if DT is not in sync,
    however this device is a BMC so the ecosystem is closed enought that
    this should not be a problem.
* srf04
  - Add power management with DT bindings for the GPIO.
* stm32-timer-trigger
  - Power management.
* (counter) stm32-timer-cnt
  - Power management.
* vcnl4000
  - Enable runtime PM for devices that don't use on demand measurement.

Cleanups and minor fixes
* core
  - Avoid double read when using debugfs.  Whilst we provide no guarantees
    on lack of side effects using the debugfs interfaces, this one is
    generate unexpected results so let us tidy it up.
* dac/Kconfig
  - Alphabetic order.
* ad5755
  - Grammar and minor other fixes.
* ad7124
  - Fail probe if get_voltage fails as no meaningful readings can be had
    without knowing the external reference.
  - Switch to selection between different channel attributes rather than
    building the arrays at runtime.
  - Remove the spi_device_id table as the driver cannot be probled without
    more information that can be provided without dt.
  - Update sysfs docs to provide more inormation and bring remaining docs for

staging: mt7621-pci: fix io space and properly set resource limits

Function 'mt7621_pci_parse_request_of_pci_ranges' is using
'of_pci_range_to_resource' to get both mem and io resources.
Internally this function calls to 'pci_address_to_pio' which
returns -1 if io space address is an address > IO_SPACE_LIMIT
which is 0xFFFF for mips. This mt7621 soc has io space in physical
address 0x1e160000. In order to fix this, overwrite invalid io
0xffffffff  with properly values from the device tree and set
mapped address of this resource as io port base memory address
calling 'set_io_port_base' function. There is also need to properly
setup resource limits and io and memory windows with properly
parsed values instead of set them as 'no limit' which it is wrong.
For any reason I don't really know legacy driver sets up mem window
as 0xFFFFFFFF and any other value seems to does not work as expected,
so set up also here with same values.

staging: mt7621-pci: use gpios for properly reset

Original driver code was using three gpio's for reset
asserts and deasserts the pcis. Instead of using that
a general reset control with a perst gpio was introduced
and it seems it is partially working but sometimes there
are some unexpected hangs on boot. This commit make use of
the three original gpios using 'reset-gpios' property of
the device tree and removes the reset line and perst gpio.
According to the mediatek aplication note v0.1 there are
three gpios used for pcie ports reset control: gpio#19,
gpio#8 and gpio#7 for slots 0, 1 and 2 respectively.
This schema can be used separately for mt7621A but in some
boards due to pin share issue, if the PCM and I2S function
are enable at the same time, there are no enough GPIO to
control per-port PCIe reset. In those cases gpio#19 is enought
for reset the three ports together. Because of this we just
try to get the three gpios but if some of them fail we are not
failing in boot process, just prints a kernel notice and take
after into account if the descriptor is or not valid in order
to use it. All of them are set as GPIO output low configuration.
The gpio descriptor's API takes device tree property into account
and invert value if the pin is configured as active low.
So we also have to properly request pins from device tree
and set values correct in assert and deassert functions.
After this changes the order to make all assert and
deassert in the 'probe' process makes more sense:
* Parse device tree.
* make assert of the RC's and EP's before doing anything else.
* make deassert of the RC's before initializing the phy.
* Init the phy.
* make deassert of the EP's before initialize pci ports.
* Normal PCI initialization.

staging: vt6656: Use BIT_ULL() macro instead of bit shift operation

Replace the bit left shift operation with the BIT_ULL() macro and remove
the unnecessary mask off operation against the bit_nr variable.

This mask is only there for legacy reasons. Originally it was 31 (0x1f)
and the bit_nr variable spread across an mc_filter array with two u32
elements. Now, this mask is not needed because its value is 0x3f and the
mc_filter variable is an u64 type.

In this situation, the 26 bit right shift operation against the value
returned by the ether_crc function set the bit_nr variable to the
following value:

bit 31 to bit 6 -> All 0 (due to the bit shift operation happens over an
unsigned type).

bit 5 to bit 0 -> The 6 msb bits of the value returned by the ether_crc
function.

The purpose of the 0x3f mask against the bit_nr variable is to reset
(set to 0) the 26 msb bits (bit 31 to bit 6), but these bits are yet 0.
So, the mask off operation is now unnecessary.

staging: vt6656: struct vnt_rcb remove unused in_use.

The variable merely toggles true to false and is unused.

staging: vt6656: Remove vnt_interrupt_buffer in_use flag.

mac80211 is the only user of in_use to start it and should
not be true when so.

So internal toggling of this variable is not relevant.

staging: wilc1000: spi: Use new structure for SPI transfer delays

In a recent change to the SPI subsystem in commit <bebcfd272df6>
("spi: introduce `delay` field for `spi_transfer` +
spi_transfer_delay_exec()"), a new `delay` struct was added
to replace the `delay_usecs`. This change replaces the current
`delay_usecs` with `delay` for this driver.

The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure
that both `delay_usecs` & `delay` are used (in this order to preserve
backwards compatibility).
