The default RGB quantization range for BT.2020 is full range (just as for
all the other RGB pixel encodings), not limited range.

Update the V4L2_MAP_QUANTIZATION_DEFAULT macro and documentation
accordingly.

Also mention that HSV is always full range and cannot be limited range.

When RGB BT2020 was introduced in V4L2 it was not clear whether it should
be limited or full range, but full range is the right (and consistent)
choice.

pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code. Thus a pairing decrement is needed on
the error handling path to keep the counter balanced. For other error
paths after this call, things are the same.

Fix this by adding pm_runtime_put_noidle() after 'err_runtime_disable'
label. But in this case, the error path after pm_runtime_put_sync()
will decrease PM usage counter twice. Thus add an extra
pm_runtime_get_noresume() in this path to balance PM counter.

When outputting SD-Core output through the TXA MIPI CSI-2 interface,
the number of enabled data lanes should be reduced in order to guarantee
that the two video formats produced by the SD-Core (480i and 576i)
generate a MIPI CSI-2 link clock frequency compatible with the MIPI D-PHY

With the removal of the legacy g_mbus_config and s_mbus_config video
operations, the sole users of V4L2_MBUS_* flags are now the newly
introduced get_mbus_config and set_mbus_config pad operations.

As the semantic of the new operations differs from the semantic of

flags with fields, to prevent users from mixing conflicting values

Move the PXA camera driver to use the new set_mbus_config pad operation.
For this platform the change is not only cosmetic, as the pxa driver is
currently the only driver in mainline to make use of the g_mbus_config
and s_mbus_config video operations.

The existing driver semantic is the following:
- Collect all supported mbus config flags from the remote end
- Match them with the supported PXA mbus configuration flags
- If the remote subdevice allows multiple options for for VSYNC, HSYNC
  and PCLK polarity, use platform data requested settings

The semantic of the new get_mbus_config and set_mbus_config differs from
the corresponding video ops, particularly in the fact get_mbus_config
reports the current mbus configuration and not the set of supported
configuration options, with set_mbus_config always reporting the actual
mbus configuration applied to the remote subdevice.

Adapt the driver to perform the following
- Set the remote subdevice mbus configuration according to the PXA
  platform data preferences.
- If the applied configuration differs from the requested one (i.e. the
  remote subdevice does not allow changing one setting) make sure that
  - The remote end does not claim for DATA_ACTIVE_LOW, which seems not
    supported by the platform
  - The bus mastering roles match

While at there remove a few checks performed on the media bus
configuration at get_format() time as they do not belong there.

Compile-tested only.

Use the new get_mbus_config and set_mbus_config pad operations in place
of the video operations currently in use.

Compared to other drivers where the same conversion has been performed,
ov6650 proved to be a bit more tricky, as the existing g_mbus_config
implementation did not report the currently applied configuration but
the set of all possible configuration options.

Adapt the driver to support the semantic of the two newly introduced
operations:
- get_mbus_config reports the current media bus configuration
- set_mbus_config applies only changes explicitly requested and updates
  the provided cfg parameter to report what has actually been applied to
  the hardware.

  got a cleanup along the way so that it's now easier to read (and

There's a bit of confusion on the matching pairs of poll vs double poll,
depending on if the request is a pure poll (IORING_OP_POLL_ADD) or
poll driven retry.

Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().

Finally ensure that wait->private is cleared once the double poll handler
has run, so that remove knows it's already been seen.

   - Enabled Regmap 'fast I/O' in stm32-lptimer
   - Change BUG_ON to WARN_ON in arizona-core
   - Remove superfluous code/initialisation (madera, max14577)
   - Trivial formatting/spelling issues (madera-core, madera-i2c, da9055, max77693-private)
   - Switch to of_platform_populate() in sprd-sc27xx-spi
   - Expand out set/get brightness/pwm macros in lm3533-ctrlbank
   - Disable IRQs on suspend in motorola-cpcap
   - Clean-up error handling in intel_soc_pmic_mrfld
   - Ensure correct removal order of sub-devices in madera
   - Many s/HTTP/HTTPS/ link changes
   - Ensure name used with Regmap is unique in syscon

  Bug Fixes
   - Properly 'put' clock on unbind and error in arizona-core
   - Fix revision handling in da9063
   - Fix 'assignment of read-only location' error in kempld-core
   - Avoid using the Regmap API when atomic in rn5t618
   - Redefine volatile register description in rn5t618
   - Use locking to protect event handler in dln2"

The ioreadX() helpers have inconsistent interface.  On some architectures
void *__iomem address argument is a pointer to const, on some not.

Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.
