Commit a22b41a31e ("sbs-battery: Probe should try talking to the
device") introduced a step in probing the SBS battery, that tries to
talk to the device before actually registering it, saying:
this driver doesn't actually try talking to the device at probe
time, so if it's incorrectly configured in the device tree or
platform data (or if the battery has been removed from the system),
then probe will succeed and every access will sit there and time
out. The end result is a possibly laggy system that thinks it has a
battery but can never read status, which isn't very useful.
Which is of course reasonable. However, it is also very well possible
for a device to boot up on wall-power and be connected to a battery
later on. This is a scenario that the driver supported before said patch
was applied, and even easily achieved by booting up with the battery
attached and removing it later on. sbs-battery's 'present' sysfs file
can be used to determine if the device is available or not.
So with automated device detection lacking for now, in some cases it is
possible that one wants to register a battery, even if none are attached
at the moment. To facilitate this, add a module parameter that can be
used to configure forced loading module loading time. If set, the battery
will always be registered without checking the sanity of the connection.

The fix for NULL pointer exception related to calling uevent for not
finished probe caused to set all writeable properties as non-writeable.
This was caused by checking if property is writeable before the initial
increase of power supply usage counter and in the same time using
wrapper over property_is_writeable(). The wrapper returns ENODEV if the
usage counter is still 0.
The call trace looked like:
device probe:
power_supply_register()
use_cnt = 0;
device_add()
create sysfs entries
power_supply_attr_is_visible()
power_supply_property_is_writeable()
if (use_cnt == 0) return -ENODEV;
use_cnt++;
Replace the usage of wrapper with direct call to property_is_writeable()
from driver. This should be safe call during device probe because
implementations of this callback just return 0/1 for different
properties and they do not access any of the driver's internal data.

If CONFIG_USB_PHY is not enabled, struct notifier_block is not defined and

notifications are defined only if CONFIG_USB_PHY is enabled.
There is no need to define these functions if CONFIG_USB_PHY is not
enabled, since no USB notifications are received in this case.
Also, since rt9455_set_boost_voltage_before_boost_mode() function is
called only if USB_EVENT_ID notification is received, this function should

gpio-restart uses a priority of 128 and currently most soc-level restart
mechanisms use the same - with some exceptions even using 192.
But while the soc-level restarts are provided by the soc itself,
gpio-restarts will most of the time be board-specfic and be used
when some special board condition makes the soc-level restart
only a second choice.
The problem at hand manifested itself on the rk3288-veyron devices.
While the soc-level restart can sucessfully restart all other rockchip
boards I have, the veyron devices use an external restart mechanism that
seems to not only reset the soc but also some external needed components.
With both restart handlers having priority 128 in my tests the soc-specific
variant took precedent in all cases. While it could restart the soc
sucessfully in all cases, firmware then got an issue when talking to an
external component, resulting in the device being put into recovery mode.
So, give the board-specific restart handler a slight push and move it
to priority 129 to make it more important than the generic soc-specific
restart-handler.

If your platform has multiple such phys (as mine does),

node by looking for an appropriately named sibling in

Don't call the power_supply_changed() from power_supply_register() when
parent is still probing because it may lead to accessing parent too
early.
In bq27x00_battery this caused NULL pointer exception because uevent of
power_supply_changed called back the the get_property() method provided
by the driver. The get_property() method accessed pointer which should
be returned by power_supply_register().
Starting from bq27x00_battery_probe():
di->bat = power_supply_register()
power_supply_changed()
kobject_uevent()
power_supply_uevent()
power_supply_show_property()
power_supply_get_property()
bq27x00_battery_get_property()
dereference of di->bat which is NULL here
The dereference of di->bat (value returned by power_supply_register())
is the currently visible problem. However calling back the methods
provided by driver before ending the probe may lead to accessing other
driver-related data which is not yet initialized.
The call to power_supply_changed() is postponed till probing ends -
mutex of parent device is released.

Power supply is often registered during probe of a driver. The
power_supply_register() returns pointer to newly allocated structure as
return value. However before returning the power_supply_register()
calls back the get_property() method provided by the driver through
uevent.
In that time the driver probe is still in progress and driver did not
assigned pointer to power supply to its local variables. This leads to
NULL pointer dereference from get_property() function.
Starting from bq27x00_battery_probe():
di->bat = power_supply_register()
device_add()
kobject_uevent()
power_supply_uevent()
power_supply_show_property()
power_supply_get_property()
bq27x00_battery_get_property()
dereference of (di->bat) which is NULL here
The first uevent of power supply (the one coming from device creation)
should not call back to the driver. To prevent that from happening,
increment the atomic use counter at the end of power_supply_register().
This means that power_supply_get_property() will return -ENODEV.
IMPORTANT:
The patch has impact on this first uevent sent from power supply because
it will not contain properties from power supply.
The uevent with properties will be sent later after indicating that
power supply has changed. This also has a race now, but will be fixed in
other patches.
