The QPNP SMB2 charger driver supports the charger peripheral present in
the PMICOBALT chip.
This charger peripheral is common among other chips, therefore the
driver uses the smb library to support all common functionality.
Register access is provided by the parent device via regmap. Interrupts
are controlled by the parent device, and handlers are registered by the
QPNP SMB2 charger driver.
The power supply framework is used to communicate battery and usb
properties to userspace and other driver consumers such as fuel gauge,
USB, and USB-PD.
VBUS and VCONN regulators are registered for supporting OTG, and powered
Type-C cables respectively.

The BTM (Battery temperature module) peripheral driver
on the PMIC (Power management IC) supports threshold
monitoring and notifies clients when thresholds are crossed.
PMCOBALT supports refreshed BTM peripheral register interface
and the driver uses compatible property qpnp-adc-tm-hc to
distinguish using the refreshed peripheral. The external
client interface with the driver remains the same. Updates
include handling the interrupt when the thresholds are
crossed,programming the threholds and configuring
the hardware based on the refreshed design.
BTM peripheral needs the VADC_HC peripheral to compute the
gain/offset that are used to reverse compute the threhold
values to ADC code. Some of the reverse computation API's
such as calculating thermistor thresholds require the
gain and offset values before computing the ADC code to
be programmed. This requires modification to the existing
calibration API in the VADC_HC driver to calculate
the reference calibration points and store these values
for clients to use in the reverse computation

The current code uses handle_level_irq flow handler even if the trigger
type of the interrupt is edge. This can lead to missing of an edge
transition that happens when the interrupt is being handled. The level
flow handler masks the interrupt while it is being handled, so if an edge
transition happens at that time, that edge is lost.
Use an edge flow handler for edge type interrupts which ensures that the
interrupt stays enabled while being handled - at least until it triggers
at which point the flow handler sets the IRQF_PENDING flag and only then
masks the interrupt. That IRQF_PENDING state indicates an edge transition
happened while the interrupt was being handled and the handler is called
again.
