Whishkey cove PMIC has support to mask/unmask interrupts at two levels.
At first level we can mask/unmask interrupt domains like TMU, GPIO, ADC,
CHGR, BCU THERMAL and PWRBTN and at second level, it provides facility
to mask/unmask individual interrupts belong each of this domain. For
example, in case of TMU, at first level we have TMU interrupt domain,
and at second level we have two interrupts, wake alarm, system alarm that
belong to the TMU interrupt domain.
Currently, in this driver all first level IRQs are registered as part of
IRQ chip(bxtwc_regmap_irq_chip). By default, after you register the IRQ
chip from your driver, all IRQs in that chip will masked and can only be
enabled if that IRQ is requested using request_irq() call. This is the
default Linux IRQ behavior model. And whenever a dependent device that
belongs to PMIC requests only the second level IRQ and not explicitly
unmask the first level IRQ, then in essence the second level IRQ will
still be disabled. For example, if TMU device driver request wake_alarm
IRQ and not explicitly unmask TMU level 1 IRQ then according to the default
Linux IRQ model, wake_alarm IRQ will still be disabled. So the proper
solution to fix this issue is to use the chained IRQ chip concept. We
should chain all the second level chip IRQs to the corresponding first
level IRQ. To do this, we need to create separate IRQ chips for every
group of second level IRQs.
In case of TMU, when adding second level IRQ chip, instead of using PMIC
IRQ we should use the corresponding first level IRQ. So the following
code will change from
ret = regmap_add_irq_chip(pmic->regmap, pmic->irq, ...)
to,
virq = regmap_irq_get_virq(&pmic->irq_chip_data, BXTWC_TMU_LVL1_IRQ);
ret = regmap_add_irq_chip(pmic->regmap, virq, ...)
In case of Whiskey Cove Type-C driver, Since USBC IRQ is moved under
charger level2 IRQ chip. We should use charger IRQ chip(irq_chip_data_chgr)
to get the USBC virtual IRQ number.

If the EC supports the new CONSOLE_READ command type, then we
place a console_log file in debugfs for that EC device which allows
us to grab EC logs. The kernel will poll every 10 seconds for the
log and keep its own buffer, but userspace should grab this and
write it out to some logs which actually get rotated.

This enables configuring the PMIC's sleep mode via device-tree.
A pointer indirection to sleep mode data is removed, as it simplifies

Lots of good stuff here, after many many many attempts, the kernel
finally has a working typeC interface, many thanks to Heikki and

wasn't an easy path for them at all.
There's also a staging driver that uses this new api, which is why

Along with that, there's the usual huge number of changes for gadget
drivers, xhci, and other stuff. Johan also finally refactored pretty
much every driver that was looking at USB endpoints to do it in a
common way, which will help prevent any "badly-formed" devices from
causing problems in drivers. That too wasn't a simple task.

MFD support for DA9061 is provided as part of the DA9062 device driver.
The registers header file adds two new chip variant IDs defined in DA9061
and DA9062 hardware. The core header file adds new software enumerations
for listing the valid DA9061 IRQs and a da9062_compatible_types enumeration
for distinguishing between DA9061/62 devices in software.
The core source code adds a new .compatible of_device_id entry. This is
extended from DA9062 to support both "dlg,da9061" and "dlg,da9062". The
.data entry now holds a reference to the enumerated device type.
A new regmap_irq_chip model is added for DA9061 and this supports the new
list of regmap_irq entries. A new mfd_cell da9061_devs[] array lists the
new sub system components for DA9061. Support is added for a new DA9061
regmap_config which lists the correct readable, writable and volatile
ranges for this chip.
The probe function uses the device tree compatible string to switch on the
da9062_compatible_types and configure the correct mfd cells, irq chip and
regmap config.
Kconfig is updated to reflect support for DA9061 and DA9062 PMICs.

Note that the macros and function prefixes have been intentionally
changed to ATMEL_[H]SMC_XX and atmel_[h]smc_ to reflect the fact that
this IP is also embedded in avr32 SoCs (and not only in at91 ones).

The registers 0x56 and 0x57 of AXP22X PMIC store the value of the
internal temperature of the PMIC.
This patch modifies the name of these registers from AXP22X_PMIC_ADC_H/L
to AXP22X_PMIC_TEMP_H/L so their purpose is clearer.

One of the features of STM32 trigger hardware block is a quadrature
encoder that can counts up/down depending of the levels and edges
of the selected external pins.
This patch allow to read/write the counter, get it direction,
set/get quadrature modes and get scale factor.
When counting up preset value is the limit of the counter.
When counting down the counter start from preset value down to 0.
This preset value could be set/get by using
/sys/bus/iio/devices/iio:deviceX/in_count0_preset attribute.

Phy drivers access PMU region through regmap provided by exynos-pmu
driver. However there is no need to duplicate defines for PMU
registers. Instead just use whatever is defined in exynos-regs-pmu.h.

This adds support for the Allwinner A33 thermal sensor.
Unlike the A10, A13 and A31, the Allwinner A33 only has one channel
which is dedicated to the thermal sensor. Moreover, its thermal sensor
does not generate interruptions, thus we only need to directly read the
register storing the temperature value.
The MFD used by the A10, A13 and A31, was created to avoid breaking the
DT binding, but since the nodes for the ADC weren't there for the A33,
it is not needed.
Though the A33 does not have an internal ADC, it has a thermal sensor
which shares the same registers with GPADC of the already supported SoCs
and almost the same bits, for the same purpose (thermal sensor).
The thermal sensor behaves exactly the same (except the presence of
interrupts or not) on the different SoCs.

For SPI, we can get up to 32 additional bytes for response preamble.
The current overhead (2 bytes) may cause problems when we try to receive
a big response. Update it to 32 bytes.
Without this fix we could see a kernel BUG when we receive a big response
from the Chrome EC when is connected via SPI.

Some form factors (detachables/tablets) may not have a keyboard and
thus user may have to resort to using a defined EC UI to send sysrq(s)
to the kernel in order to collect crash info etc. This UI typically
is in the form of user pressing volume / power buttons in some specific
sequence and for some specific time. Add a new EC event that allows EC
to communicate the sysrq to the AP.
(We're skipping event number 5 because it has been reserved for
something else)

The Allwinner SoCs all have an ADC that can also act as a touchscreen
controller and a thermal sensor. This patch adds the ADC driver which is
based on the MFD for the same SoCs ADC.
This also registers the thermal adc channel in the iio map array so
iio_hwmon could use it without modifying the Device Tree. This registers
the driver in the thermal framework.
The thermal sensor requires the IP to be in touchscreen mode to return
correct values. Therefore, if the user is continuously reading the ADC
channel(s), the thermal framework in which the thermal sensor is
registered will switch the IP in touchscreen mode to get a temperature
value and requires a delay of 100ms (because of the mode switching),
then the ADC will switch back to ADC mode and requires also a delay of
100ms. If the ADC readings are critical to user and the SoC temperature
is not, this driver is capable of not registering the thermal sensor in
the thermal framework and thus, "quicken" the ADC readings.
This driver probes on three different platform_device_id to take into
account slight differences (registers bit and temperature computation)
between Allwinner SoCs ADCs.
