If the feature query fails during this driver's probe, we memset the
features bits to 0, but then we continue to overwrite that with whatever
junk we read back when the feature probing failed. In the case of a SPI
device, it may be complete junk, causing the caller of this function to
think certain features are present when they aren't. Don't copy over the
bad message on failure so we can fail more gracefully.

Intel Cannon Lake PCH has much higher 216 MHz input clock to LPSS I2C
than Sunrisepoint which uses 120 MHz. Preliminary information was that
both share the same clock rate but actual silicon implements elevated
rate for better support for 3.4 MHz high-speed I2C.
This incorrect input clock rate results too high I2C bus clock in case
ACPI doesn't provide tuned I2C timing parameters since I2C host
controller driver calculates them from input clock rate.
Fix this by using the correct rate. We still share the same 230 ns SDA
hold time value than Sunrisepoint.

As Google/Intel will fix the BIOS/Coreboot issues with hardcoding
virtual interrupt numbers for keyboard/touchpad/touchscreen controllers
in ACPI tables, they will also update BOARD version number from 1.0
to 1.1. Let's limit the DMI quirks that try to preserve virtual IRQ
numbers on Strago boards to those that still carry older BIOSes.
Note that ideally not BOARD but BIOS version should have been updated.
However the BIOS version used by Chrome devices has format of
Google_BUILD.BRANCH.PATCH which is not well suited for DMI matching as
we do not have "less than" match mode for DMI data.

With the addition of "private_objs" in drm_atomic_state, we no longer
need to subclass drm_atomic_state to store state of share resources
that don't perfectly fit within planes/crtc/connector state information.
We can now save this state within drm_atomic_state itself using
the private objects.
Remove the infrastructure that allowed subclassing of drm_atomic_state
in the driver.

This replaces the usage of the subclassed atomic state (mdp5_state)
with a private_obj state embedded within drm_atomic_state. The latter
method is the preferred approach, since it's simpler to implement
and less prone to errors.
The new API replaces the older and equivalent mdp5_state usage in the
following pattern:
- References to "mdp5_kms->state" (i.e, the old/existing state) is
replaced with mdp5_get_existing_global_state(). In the atomic_check
path, this should be called with the glob_state_lock drm_modeset_lock
alredy taken.
- References to "mdp5_get_state()" are replaced with
mdp5_get_global_state(). This acquires glob_state_lock and uses
drm_atomic_get_private_obj_state() to create a new duplicated state.
Changes in v3:
- Acquire glob_state_lock in mdp5_smp.c
- Added to the msm atomic helper patch set
Changes in v4:
- None

Global shared resources (hwpipes, hwmixers and SMP) for MDP5 are
implemented as a part of atomic state by subclassing drm_atomic_state.
The preferred approach is to use the drm_private_obj infrastructure
available in the atomic core.
mdp5_global_state is introduced as a drm atomic private object. The two
funcs mdp5_get_global_state() and mdp5_get_existing_global_state() are
the two variants that will be used to access mdp5_global_state.
This will replace the existing mdp5_state struct (which subclasses
drm_atomic_state) and the funcs around it. These will be removed later
once we mdp5_global_state is put to use everywhere.
Changes in v3:
- Added glob_state_lock instead of pushing it into the core
- Added to the msm atomic helper patch set
Changes in v4:
- None

Currently the error pointer returned by msm_alloc_stolen_fb gets passed
to drm_framebuffer_remove. The latter handles only NULL pointers, thus
a nasty crash will occur.
Drop the unnecessary fail label and the associated checks - both err and
fb will be set at this stage.

Commit 62e3a3e342af changed get_pages() to initialise
msm_gem_object::pages before trying to initialise msm_gem_object::sgt,
so that put_pages() would properly clean up pages in the failure
case.
However, this means that put_pages() now needs to check that
msm_gem_object::sgt is not null before trying to clean it up, and
this check was only applied to part of the cleanup code. Move
it all into the conditional block. (Strictly speaking we don't
need to make the kfree() conditional, but since we can't avoid
checking for null ourselves we may as well do so.)

The "Clear Error Unit" may be smaller than the ECC unit size on some
devices. For example, poison may be tracked at 64-byte alignment even
though the ECC unit is larger. Unless / until the ACPI specification
provides a non-ambiguous way to communicate this property do not expose
this to userspace.
Software that had been using this property must already be prepared for
the case where the property is not provided on older kernels, so it is
safe to remove this attribute.
