Pull ACPI fixes from Rafael Wysocki:
"These fix an ACPI initialization ordering issue introduced in the 4.17
time frame and causing functional problems to appear on multiple
systems and fix some fallout of the recent change to enable building
kernels with ACPI support and without PCI.
Specifics:
- Restore the ACPI initialization ordering changed implicitly by the
module-level AML handling rework during the 4.17 development cycle
that caused the EC address space handler based on information from
ECDT to be set up before loading AML definition blocks, making it
effectively not accessible by AML on some systems that don't work
as expected any more (Rafael Wysocki).
- Add direct dependencies on PCI to Kconfig in multiple places for
code that depends on both ACPI and PCI, but the PCI dependency was
implicitly satisfied by the ACPI dependency before, to prevent
invalid configurations from being created, for example by
randconfig (Sinan Kaya)"

Since commit d4ccceb055 ("drm/i915/icl: Ringbuffer interrupt handling")
we have required a mechanism to avoid touching the interrupt hardware
for breadcrumbs, superseding our mock interface for selftests.
The residual problem (ideas welcome) is in probing the mock ring
registers for ring_is_idle. Hmm, maybe we should just install
mock handlers for i915->uncore.mmio__write and friends? Only problem
being is that we would to truly mock some expected reads. :(

The initial series is only introducing the basic components and not
implementing IRQ handling. Remove the left over code that touches
IRQs until the proper implementation is introduced in a later series.

The motivation for introducing the check that we only enable breadcrumb
irqs if the device's irq was installed was once upon a time we waited
during suspend after disabling interrupts (which was quite slow until
the bug was discovered). Since then we have the notion of pinning the
breadcrumb irq, broadening it from the sole purpose of user interrupt
notification and waiting, and more importantly decoupling it from a very
defined time period during which enabling the irq was expected. So stop
insisting the irq is installed before we setup our IMR masks, if the IER
isn't yet enabled, nothing will happen and we will timeout instead,
revealing the lack of irq in the hang debug messages.

The device node iterators perform an of_node_get on each
iteration, so a jump out of the loop requires an of_node_put.
Move the initialization channel->child = child; down to just
before the call to imx_ldb_register so that intervening failures
don't need to clear it. Add a label at the end of the function to
do all the of_node_puts.
The semantic patch that finds part of this problem is as follows

Also enable the damage plane property for all except repaper which can

[Why]
Backlight is conceptually a property of links, not streams.
All backlight programming is done on links, but there is a
stream property bl_pwm_level that is used to restore backlight
on dpms on and s3 resume. This is unnecessary, as backlight
is already restored by hardware with no driver intervention.
[How]
Remove bl_pwm_level, and the stream argument to set_backlight

(cherry picked from commit 923fe49512)
To support interlaced scan with planar formats, cpmem SLUV must
be programmed with the correct chroma line stride. For full and
partial planar 4:2:2 (YUV422P, NV16), chroma line stride must
be doubled. For full and partial planar 4:2:0 (YUV420, YVU420, NV12),
chroma line stride must _not_ be doubled, since a single chroma line
is shared by two luma lines.

The function ipu_csi_init_interface() was inverting the F-bit for
NTSC case, in the CCIR_CODE_1/2 registers. The result being that
for NTSC bottom-top field order, the CSI would swap fields and
capture in top-bottom order.
Instead, base field swap on the field order of the input to the CSI,
and the field order of the requested output. If the input/output
fields are sequential but different, swap fields, otherwise do
not swap. This requires passing both the input and output mbus
frame formats to ipu_csi_init_interface().
Move this code to a new private function ipu_csi_set_bt_interlaced_codes()
that programs the CCIR_CODE_1/2 registers for interlaced BT.656 (and
possibly interlaced BT.1120 in the future).
When detecting input video standard from the input frame width/height,
make sure to double height if input field type is alternate, since
in that case input height only includes lines for one field.

The audio setting implementation was limited to a few specific pixel
clocks. This prevented HDMI audio from working on several test devices
as they need a pixel clock that is not supported by this implementation.
Fix this by implementing the algorithm provided in the TRM using fixed
point arithmetic. This allows the driver to cope with any sane pixel
clock rate.
