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 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 API
I'm going to queue up this series for v4.5.
If there are any problems with it or objections from anyone, please let me know.
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?
There were a few.
All of them are in my linux-next branch if you can try this one.
Alternatively, I can expose a branch with these to you to test.
I picked up all the patches from the device-properties merge but the
problem still shows up. Are there others I should pick up? Hardware
details about the touchpad are at https://bugzilla.redhat.com/show_bug.cgi?id=1275718#c34
Well, in that case can you please ask the reporter to bisect?
Rafael
I'll see if I can help the reporter bisect although it looks like Hans
has an idea about what might be failing.
Thanks,
Laura
