Because ddr freq scanning may get clk mutex than get drm general
mutex to get lcdc_type. But when drm status change, drm may get drm
general mutex first and than get clk mutex. This may cause deadlock.
So when get lcdc type we change to use drm_modeset mutex to avoid
deadlock.

For device nodes in both DT and ACPI, it possible to have named
child nodes which contain properties (an existing example being
gpio-leds). This adds a function to find a named child node for
a device which can be used by drivers for property retrieval.
For DT data node name matching, of_node_cmp() and similar functions
are made available outside of CONFIG_OF block so the new function
can reference these for DT and non-DT builds.
For ACPI data node name matching, a helper function is also added
which returns false if CONFIG_ACPI is not set, otherwise it
performs a string comparison on the data node name. This avoids
using the acpi_data_node struct for non CONFIG_ACPI builds,
which would otherwise cause a build failure.

Sometimes, we would abort suspend work before it finished.
In this case, suspend work would try to resume the part suspended
by correspond resume functions.
But the suspend/resume functions are not matched in rockchip.
When the suspend work is aborted, it would ignored resuming this
part due to can't find correspond resume functions.
So, let's use suspend_late instead of suspend.

on the situation that: charger is connected and fuel gauge gives
state 'CC or CV', but actually battery is discharging from 100%
to 99%. At this moment we may treat this as normal full charging
by mistake, so we must add current judgement to avoid that.
