The Linux Power Supply framework expects battery temperatures to have
a resolution of 0.1 degree Celsius; however, the AB8500 btemp driver
supplies a battery temperature resolution of 1 degree Celsius. We
therefore have to use a factor 10 on the measured values.

Today the battery recharge is determined with a voltage threshold. This
voltage threshold is only valid when the battery is relaxed. In charging
algorithm the voltage read is the loaded battery voltage and no
compensation is done to get the relaxed voltage. When maintenance
charging is not selected, this makes the recharging condition to almost
immediately activate when there is a discharge present on the battery.
Depending on which vendor the battery comes from this behavior can wear
out the battery much faster than normal.
The fuelgauge driver is responsible to monitor the actual battery
capacity and is able to estimate the remaining capacity. It is better to
use the remaining capacity as a limit to determine when battery should
be recharged.

The lp8788-charger is a platform driver of lp8788-mfd. The platform device
is allocated when mfd_add_devices() is called in lp8788-mfd. On the other
hand, 'lp->dev' is the i2c client device.
Therefore, this 'platform_device' is a proper parent device in case of
resource managed mem alloc and device kernel message.

x = devm_kzalloc(...)

As most of the charger chips come with two kinds of safety features
related to timing:
1. Watchdog Timer (interms of seconds/mins)
2. Safety Timer (interms of hours)
This patch adds these to fault causes in POWER_SUPPLY_PROP_HEALTH_* enums
so that whenever there is either watchdog timeout or safety timer timeout
driver could notify the user space accurately about the fault and will
also be helpful for debug.

There's no need to test whether a (delayed) work item in pending
before queueing, flushing or cancelling it. Most uses are unnecessary
and quite a few of them are buggy.
Remove unnecessary pending tests and rewrite _setup_polling() so that
it uses mod_delayed_work() if the next polling interval is sooner than
currently scheduled. queue_delayed_work() is used otherwise.
Only compile tested. I noticed that two work items - setup_polling
and cm_monitor_work - schedule each other. It's a very unusual
construct and I'm fairly sure it's racy. You can't break such
circular dependency by calling cancel on each. I strongly recommend
revising the mechanism.

* 'fixes-for-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds:
leds: leds-gpio: set devm_gpio_request_one() flags param correctly
|
|
commit a99d76f leds: leds-gpio: use gpio_request_one
changed the leds-gpio driver to use gpio_request_one() instead
of gpio_request() + gpio_direction_output()
Unfortunately, it also made a semantic change that breaks the
leds-gpio driver.
The gpio_request_one() flags parameter was set to:
GPIOF_DIR_OUT | (led_dat->active_low ^ state)
Since GPIOF_DIR_OUT is 0, the final flags value will just be the
XOR'ed value of led_dat->active_low and state.
This value were used to distinguish between HIGH/LOW output initial
level and call gpio_direction_output() accordingly.
With this new semantic gpio_request_one() will take the flags value
of 1 as a configuration of input direction (GPIOF_DIR_IN) and will
call gpio_direction_input() instead of gpio_direction_output().
int gpio_request_one(unsigned gpio, unsigned long flags, const char *label)
{
..
if (flags & GPIOF_DIR_IN)
err = gpio_direction_input(gpio);
else
err = gpio_direction_output(gpio,
(flags & GPIOF_INIT_HIGH) ? 1 : 0);
..
}
The right semantic is to evaluate led_dat->active_low ^ state and
set the output initial level explicitly.

Ulrich reported that his USB3 cardreader does not work reliably when
connected to the USB3 port. It turns out that USB3 controller failed to
awaken when plugging in the USB3 cardreader. Further experiments found
that the USB3 host controller can only be awakened via polling, not via PME
interrupt. But if the PCIe port to which the USB3 host controller is
connected is suspended, we cannot poll the controller because its config
space is not accessible when the PCIe port is in a low power state.
To solve the issue, the PCIe port will not be suspended if any subordinate
device needs PME polling.
[bhelgaas: use bool consistently rather than mixing int/bool]
