Allowing 'data_role' and 'power_role' sysfs attributes to
be writeable implies that they can be changed independently.
This is only true if there is a PD-capable device attached,
otherwise the write permission should not be set.
Also make sure to call dual_role_instance_changed() at the
conclusion of initiating a DR swap in order to trigger the
is_writeable() callback to update the permissions. Note that
the PR swap case is already handled during the call to
usbpd_set_state(PE_{SRC,SNK}_READY).

dual_role_instance_changed() is called by drivers when updating
the state of the dual_role port device. In some cases a driver
may wish to dynamically update the visibility, in particular the
write permissions of some of its attributes. For instance,
'data_role' and 'power_role' can be writeable if they can be
changed independently, as in the case of a USB PD capable device,
but may need to be set back to non-writeable when a non-PD device
is attached.
Add a call to sysfs_update_group() in dual_role_changed_work()
which updates the attributes by calling the .is_visible() callback
again, which in turn calls dual_role_property_is_writeable() to
re-check whether write permission should be set or not. Move
dual_role_changed_work() toward the end of the file as it now
needs the definition of dual_role_attr_group.

Currently BCL LMH algorithm enable request goes for every time BCL
threshold enablement. It needs to be enabled only once. So Enable
BCL LMH algorithm only once.

Just after enabling BCL, reading and evaluating current battery SoC
is bypassed. Because of this, during this same time if battery SoC
is less than preset threshold, BCL doesn't mitigate until next battery
SoC change notification comes. Fix battery SoC read and evaluation
path whenever BCL is enabled.

Presently fastmap iommu feature allocates page tables for
full 4GB virtual address space. This can be optimized to
consider virtual address range [base, size] needed by
client and prepare page tables only for applicable
region.

If ESR value goes to 0 because of some hardware issue, there is
no way to recover it back from that state. This causes incorrect
SOC reporting leading to a bad user experience. Hence add support
to clamp ESR value based on user defined DT property so that ESR
can be clamped to this value once it is found to go below it.
Since this change modifies ESR value in SRAM, having FG_SRAM_ESR
property would make encode and decode the value easier. Hence
remove fg_get_battery_esr() and get it from FG_SRAM_ESR property.

Add sysfs files for user applications to restrict
the battery charge current (FCC). The two files in
/sys/class/qcom-battery/ are -
1. restricted_charging: To enable/disable this feature
2. restricted_current: Restricted FCC (uA)
The default restricted_current value is 1A.
