This series includes few logical sets that bring a support of non-ACPI
platforms for Intel Skylake.
First part is a refactoring of built-in device properties support:
- keep single value inside the structure
- provide helper macros to define built-in properties
- fall back to secondary fwnode if primary has no asked property
Second one is modifications to MFD code and intel-lpss.c driver in particular
to define and pass built-in properties to the individual drivers.
Last part is a fix for I2C bug found on Lenovo Yoga hardware and a first
converted user.
Built-in device properties is an alternative to platform data. It provides a
unified API that drivers can use to cover all cases at once: DT, ACPI, and
built-in properties.
With this series applied platform data can be considered obsolete. Moreover,
built-in device properties allows to adjust existing configuration, for
example, in cases when ACPI values are wrong on some platforms.
The series has been tested on available hardware and doesn't break current
behaviour. But we ask you, Kevin, to apply the series on your side and check
with Lenovo hardware.
Andy Shevchenko (8):
device property: always check for fwnode type
device property: rename helper functions
device property: refactor built-in properties support
device property: keep single value inplace
device property: improve readability of macros
device property: return -EINVAL when property isn't found in ACPI
device property: Fallback to secondary fwnode if primary misses the
property
mfd: core: propagate device properties to sub devices drivers
Heikki Krogerus (1):
device property: helper macros for property entry creation
Mika Westerberg (4):
mfd: intel-lpss: Add support for passing device properties
mfd: intel-lpss: Pass HSUART configuration via properties
mfd: intel-lpss: Pass SDA hold time to I2C host controller driver
i2c: designware: Convert to use unified device property API
