The AC power supply input can be used as a wakeup source. Hook up the
ACIN_PLUGIN IRQ to trigger wakeup based on userspace configuration.
To do this, we must remember the list of IRQs for the life of the
device. To know how much space to allocate for the flexible array
member, we switch from using a NULL sentinel to using an array length.
Because we now depend on the specific order of the IRQs (we assume
ACIN_PLUGIN is first and always present), failing to acquire an IRQ
during probe must be a fatal error.
To avoid spuriously waking up the system when the AC power supply is
not configured as a wakeup source, we must explicitly disable all non-
wake IRQs during system suspend. This is because the SoC's NMI input is
shared among all IRQs on the AXP PMIC. Due to the use of regmap-irq, the
individual IRQs within the PMIC are nested threaded interrupts, and are
therefore not automatically disabled during system suspend.
The upshot is that if any other device within the MFD (such as the power
key) is an enabled wakeup source, all enabled IRQs within the PMIC will
cause wakeup. We still need to call enable_irq_wake() when we *do* want
wakeup, in case those other wakeup sources on the PMIC are all disabled.

AXP803/AXP813 have a flag that enables/disables the AC power supply
input. This flag does not affect the status bits in PWR_INPUT_STATUS.
Its effect can be verified by checking the battery charge/discharge
state (bit 2 of PWR_INPUT_STATUS), or by examining the current draw on
the AC input.
Take this flag into account when getting the ONLINE property of the AC
input, on PMICs where this flag is present.

This header file now only includes the cros_ec_dev struct, however, is the
'include/linux/platform_data/cros_ec_proto.h' who contains the definition of
all the Chrome OS EC related structs. There is no reason to have a
separate include for this struct so move to the place where other
structs are defined. That way, we can remove the include itself, but also
simplify the common pattern
#include <linux/mfd/cros_ec.h>
#include <linux/platform_data/cros_ec_proto.h>
for a single include
#include <linux/platform_data/cros_ec_proto.h>
The changes to remove the cros_ec.h include were generated with the
following shell script:
git grep -l "<linux/mfd/cros_ec.h>" | xargs sed -i '/<linux\/mfd\/cros_ec.h>/d'

CPR (Core Power Reduction) is a technology that reduces core power on a
CPU or other device. It reads voltage settings in efuse from product
test process as initial settings.
Each OPP corresponds to a "corner" that has a range of valid voltages
for a particular frequency. While the device is running at a particular
frequency, CPR monitors dynamic factors such as temperature, etc. and
adjusts the voltage for that frequency accordingly to save power
and meet silicon characteristic requirements.
This driver is based on an RFC by Stephen Boyd[1], which in turn is
based on work by others on codeaurora.org[2].

to the USB devices connected to the charge controller. An easy way to

The ADC in the JZ4740 can work either in high-precision mode with a 2.5V
range, or in low-precision mode with a 7.5V range. The code in place in
this driver will select the proper scale according to the maximum
voltage of the battery.
The JZ4770 however only has one mode, with a 6.6V range. If only one
scale is available, there's no need to change it (and nothing to change
it to), and trying to do so will fail with -EINVAL.

Let's allow reconfiguring the cpcap-charger max charge voltage and
default to 4.2V that should be safe for the known users.
This allows the users to use 4.35V for the extra capacity if really
needed at a cost of probably shorter battery life. We check the
constant charge voltage limit set by the battery.
Some pieces of the property setting code is based on an earlier patch
from Pavel Machek <[email protected]> but limited to configuring the charge
voltage for now.
