unmaintained/xiaomi-wt88047-downstream: new device (Xiaomi Redmi 2) (MR 2085)
This device port is unmaintained: The mainline port (xiaomi-wt88047) is preferred. This is only intended for testing, and was used to validate the battery/charging driver as one example. Various patches are used for the downstream kernel that expose helpful information for debugging. [ci:skip-build]: already built successfully in CI

Subject: [PATCH] power: smb1360: Fix issue for safety-timer setting
|
||||
|
||||
Safety-timer means maximum duration in minutes that a single charge
|
||||
cycle may last.
|
||||
Fix issue by correcting the safety timer enable bit.

|

Change SMB1360 configuration to match what we use for the mainline driver.
|
||||
This makes it easier to compare the registers programmed by the downstream driver
|
||||
with the mainline driver.
|
||||
|
||||
qcom,config-hard-thresholds enables an ugly hack that requires monitoring the
|
||||
battery temperature from the kernel (instead of letting the hardware do its job).
|
||||
The mainline kernel does not implement this, so disable it on downstream as well.
