Subject: [PATCH 01/16] device property: always check for fwnode type
Currently the property accessors unconditionally fall back to built-in property
set as a last resort. Make this strict and return an error in case the type of
fwnode is unknown.
This is actually a follow up to the commit 4fa7508e9f1c (device property:
Return -ENXIO if there is no suitable FW interface).

Subject: [PATCH 02/16] device property: rename helper functions
To be in align with the rest of fwnode types we rename the built-in property
set ones, i.e.
is_pset() -> is_pset_node()
to_pset() -> to_pset_node()
There is no functional change.

Subject: [PATCH 03/16] device property: refactor built-in properties support
Instead of using the type and nval fields we will use length (in bytes) of the
value. The sanity check is done in the accessors.
The built-in property accessors are split in the same way such as device tree.

Subject: [PATCH 08/16] device property: Fallback to secondary fwnode if
primary misses the property
The struct fwnode has notion of secondary fwnode. This is supposed to used
as fallback if the primary firmware interface (DT, ACPI) does not have the
property in question.
However, the current implementation never checks the secondary node which
prevents one to add default "built-in" properties to devices.
This patch adds fallback to the secondary fwnode if the primary fwnode
returns that the property does not exists.

Subject: [PATCH 09/16] device property: Take a copy of the property set
It is convenient if the property set associated with the device secondary
firmware node is a copy of the original. This allows passing property set
from a stack for example for devices created dynamically. This also ties
the property set lifetime to the associated device.
Because of that we provide new function device_remove_property_set() that
is used to disassociate and release memory allocated for the property set.

Make it possible to pass built-in device properties to platform device
drivers. This is useful if the system does not have any firmware interface
like Device Tree or ACPI which provides these.
Properties associated with the platform device will be automatically
released when the corresponding device is removed.

Subject: [PATCH 11/16] driver core: Do not overwrite secondary fwnode with
NULL if it is set
If multiple devices share single firmware node like it is case with MFD
devices, the same firmware node (ACPI) is assigned to all of them. The
function also modifies the shared firmware node in order to preserve
secondary firmware node of the device in question.
If the new device which is sharing the firmware node does not have
secondary node it will be NULL which will be assigned to the secondary node
of the shared firmware node losing all built-in properties.
Prevent this by setting the secondary firmware node only if the replacement
is non-NULL.
Print also warning if someone tries to overwrite secondary node that has
already been assigned.

Subject: [PATCH 13/16] mfd: intel-lpss: Add support for passing device
properties
If the boot firmware does not support ACPI we need a way to pass device
configuration information to the drivers. The unified device properties API
already supports passing platform data via properties so let's take
advantage of that and allow probe drivers to pass set of properties to the
host controller driver.
In order to do that we need to be able to modify the MFD cell corresponding
the host controller, so make the core driver to take copy of the cell
instead of using it directly. Then we can assign info->pset to the
resulting copy of a cell and let the MFD core to assign that to the
resulting device.

Subject: [PATCH 14/16] mfd: intel-lpss: Pass SDA hold time to I2C host
controller driver
Intel Skylake the LPSS I2C pad circuit has internal delays that require
programming non-zero SDA hold time for the I2C host controller. If this is
not done communication to slave devices may fail with arbitration lost
errors like the one seen below taken from Lenovo Yoga 900:
i2c_hid i2c-SYNA2B29:00: Fetching the HID descriptor
i2c_hid i2c-SYNA2B29:00: __i2c_hid_command: cmd=20 00
i2c_designware i2c_designware.1: i2c_dw_handle_tx_abort: lost arbitration
To fix this we follow what the Windows driver is doing and pass the default
SDA hold time of 230 ns to all Intel Skylake host controllers. This still
allows the platform to override these values by passing special ACPI
methods SSCN and FMCN.

Subject: [PATCH 16/16] i2c: designware: Convert to use unified device property
API
With ACPI _DSD (introduced in ACPI v5.1) it is now possible to pass device
configuration information from ACPI in addition to DT. In order to support
this, convert the driver to use the unified device property accessors
instead of DT specific.
Change to ordering a bit so that we first try platform data and if that's
not available look from device properties. ACPI *CNT methods are then used
as last resort to override everything else.
