[ Upstream commit 58e4a2d27d ]
The extcon_get_extcon_dev() function returns error pointers on error,
NULL when it's a -EPROBE_DEFER defer situation, and ERR_PTR(-ENODEV)
when the CONFIG_EXTCON option is disabled. This is very complicated for
the callers to handle and a number of them had bugs that would lead to
an Oops.
In real life, there are two things which prevented crashes. First,
error pointers would only be returned if there was bug in the caller
where they passed a NULL "extcon_name" and none of them do that.
Second, only two out of the eight drivers will build when CONFIG_EXTCON
is disabled.
The normal way to write this would be to return -EPROBE_DEFER directly
when appropriate and return NULL when CONFIG_EXTCON is disabled. Then
the error handling is simple and just looks like:
dev->edev = extcon_get_extcon_dev(acpi_dev_name(adev));
if (IS_ERR(dev->edev))
return PTR_ERR(dev->edev);
For the two drivers which can build with CONFIG_EXTCON disabled, then
extcon_get_extcon_dev() will now return NULL which is not treated as an
error and the probe will continue successfully. Those two drivers are
"typec_fusb302" and "max8997-battery". In the original code, the
typec_fusb302 driver had an 800ms hang in tcpm_get_current_limit() but
now that function is a no-op. For the max8997-battery driver everything
should continue working as is.

[ Upstream commit 5ac121b81b ]
The AXP288's recommended and factory default Vhold value (minimum
input voltage below which the input current draw will be reduced)
is 4.4V. This lines up with other charger IC's such as the TI
bq2419x/bq2429x series which use 4.36V or 4.44V.
For some reason some BIOS-es initialize Vhold to 4.6V or even 4.7V
which combined with the typical voltage drop over typically low
wire gauge micro-USB cables leads to the input-current getting
capped below 1A (with a 2A capable dedicated charger) based on Vhold.
This leads to slow charging, or even to the device slowly discharging
if the device is in heavy use.
As the Linux AXP288 drivers use the builtin BC1.2 charger detection
and send the input-current-limit according to the detected charger
there really is no reason not to use the recommended 4.4V Vhold.
Set Vhold to 4.4V to fix the slow charging issue on various devices.
There is one exception, the special-case of the HP X2 2-in-1s which
combine this BC1.2 capable PMIC with a Type-C port and a 5V/3A factory
provided charger with a Type-C plug which does not do BC1.2. These
have their input-current-limit hardcoded to 3A (like under Windows)
and use a higher Vhold on purpose to limit the current when used
with other chargers. To avoid touching Vhold on these HP X2 laptops
the code setting Vhold is added to an else branch of the if checking
for these models.
Note this also fixes the sofar unused VBUS_ISPOUT_VHOLD_SET_MASK
define, which was wrong.

AXP PMICs internally have two different ADC channels for shunt current

The values reported by these ADCs are unsigned.
While the driver properly selects ADC channel to get the data from,
it doesn't apply negative sign when reporting discharging current.

The HRTimer in the AB8500 charging code is using CLOCK_REALTIME
to set an alarm some hours forward in time +/- 5 min for a safety
timer.
I have observed that this will sometimes fire sporadically
early when charging a battery with the result that
charging stops.
As CLOCK_REALTIME can be subject to adjustments of time from
sources such as NTP, this cannot be trusted and will likely
for example fire events if the clock is set forward some hours
by say NTP.
Use CLOCK_MONOTONIC as indicated in other instances and the
problem goes away. Also initialize the timer to REL mode
as this is what will be used later.

^
3 errors generated.
This happens due to the use of a 'long double' literal. The 'E6' part of
'1E6L' causes the literal to be a 'double' then the 'L' suffix promotes
it to 'long double'.
There is no visible reason for floating point values in this driver, as
the values are only assigned to integer types. Use NSEC_PER_MSEC, which
is the same integer value as '1E6L', to avoid changing functionality but
fix the error.

Clean up a handful of checkpatch warnings:
- static const char * array should probably be static const char * const
- function arguments should have identifier names
- else should follow close brace '}'
- suspect code indent for conditional statements
- unnecessary parentheses in an if condition
- avoid multiple line dereference
- remove debug showing function execution, ftrace can trace these better
- prefer 'long' over 'long int' as the int is unnecessary

platform_get_irq_byname() logs an error message, so remove

MAX77849 is a combined fuel-gauge, charger and MUIC IC. Notably,
fuel-gauge has dedicated i2c lines and seems to be fully compatible
with max17047. Add new compatible for it reusing max17047 code paths.
