[ Upstream commit b2f6cb78eaa1cad57dd3fe11d0458cd4fae9a584 ]
pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to call pm_runtime_put_noidle will result
in reference leak in callers(bq24190_sysfs_show,
bq24190_charger_get_property, bq24190_charger_set_property,
bq24190_battery_get_property, bq24190_battery_set_property),

[ Upstream commit a0f1ccd96c7049377d892a4299b6d5e47ec9179d ]
Commit 9c80662a74cd ("power: supply: axp288_charger: Add special handling
for HP Pavilion x2 10") added special handling for HP Pavilion x2 10
models which use the weird combination of a Type-C connector and the
non Type-C aware AXP288 PMIC.This special handling was activated by a DMI match a the product-name
of "HP Pavilion x2 Detachable". Recently I've learned that there are
also older "HP Pavilion x2 Detachable" models with an AXP288 PMIC +
a micro-usb connector where we should not activate the special handling
for the Type-C connectors.Extend the matching to also match on the DMI board-name and match on the
2 boards (one Bay Trail based one Cherry Trail based) of which we are
certain that they use the AXP288 + Type-C connector combination.Note the DSDT code from these older (AXP288 + micro-USB) models contains
some AML code (which never runs under Linux) which reads the micro-USB
connector id-pin and if it is pulled to ground, which would normally mean
the port is in host mode!, then it sets the input-current-limit to 3A,
it seems HP is using the micro-USB port as a charging only connector
and identifies their own 3A capable charger though this hack which is a
major violation of the USB specs. Note HP also hardcodes a 2A limit
when the id-pin is not pulled to ground, which is also in violation
of the specs.I've no intention to add support for HP's hack to support 3A charging
on these older models. By making the DMI matches for the Type-C equipped
models workaround more tighter, these older models will be treated just
like any other AXP288 + micro-USB equipped device and the input-current
limit will follow the BC 1.2 spec (using the defacto standard values
there where the BC 1.2 spec defines a range).Fixes: 9c80662a74cd ("power: supply: axp288_charger: Add special handling for HP Pavilion x2 10")

Pull ARM SoC platform updates from Olof Johansson:
"SoC changes, a substantial part of this is cleanup of some of the
older platforms that used to have a bunch of board files.In particular:
- Remove non-DT i.MX platforms that haven't seen activity in years,
it's time to remove them.- A bunch of cleanup and removal of platform data for TI/OMAP
platforms, moving over to genpd for power/reset control (yay!)- Major cleanup of Samsung S3C24xx and S3C64xx platforms, moving them
closer to multiplatform support (not quite there yet, but getting
close).There are a few other changes too, smaller fixlets, etc. For new
platform support, the primary ones are:- New SoC: Hisilicon SD5203, ARM926EJ-S platform.

Pull more power management updates from Rafael Wysocki:
"First of all, the adaptive voltage scaling (AVS) drivers go to new

structure behind if it cannot be registered (Chen Yu).- Fix domain detection in the RAPL power capping driver and prevent
it from failing to enumerate the Psys RAPL domain (Zhang Rui).- Allow acpi-cpufreq to use ACPI _PSD information with Family 19 and

However, this increases exposure of the driver question not only to
Sparx5 platforms, but to everyone. Hence re-add the dependency on
