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 is a propagating built-in device properties in platform core. Third one is modifications to MFD code and intel-lpss.c driver in particular to define and pass built-in properties to the individual drivers. And 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 a platform data can be considered obsolete. Moreover, built-in device properties allow to adjust the 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 people who have the affected hardware to apply the series on your side and check with Lenovo hardware. Changelog v2: - fix isuues found by kbuild bot (kbuild) - append a patch to propagate device properties in polatform code (Arnd) - update few existing and add couple of new patches due to above - check with kmemleak Andy Shevchenko (9): 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 mfd: intel-lpss: Pass HSUART configuration via properties Heikki Krogerus (1): device property: helper macros for property entry creation Mika Westerberg (6): device property: Take a copy of the property set driver core: platform: Add support for built-in device properties driver core: Do not overwrite secondary fwnode with NULL if it is set mfd: intel-lpss: Add support for passing device properties mfd: intel-lpss: Pass SDA hold time to I2C host controller driver i2c: designware: Convert to use unified device property APII'm going to queue up this series for v4.5.

Raising an old thread, I pulled this series into Fedora rawhide and while it worked for Lenovo Yoga we received a report that it caused a regression on the Dell Inspiron 7559 (see https://bugzilla.redhat.com/show_bug.cgi?id=1275718#c27) . I haven't asked the reporter about bisecting to see which patch broke it. Were there any known follow up patches?
