All interrupt get disabled during system suspend and enabled during system
resume. The enabling/disabling of interrupt happen in sequence of
interrupt registration with framework.Therefore, in resume, the parent interrupt of this device enabled before
the RTC irq interrupt enabled. If RTC is enabled for alarm wake and if
system wake by alarm then there is interrupt pending for RTC. In resume,
the parent interrupt get enabled before the rtc interrupt and hence ISR
get served. In ISR, it founds that rtc interrupt is disabled and so it
does not call the rtc isr handler and hence it misses the interrupt.Setting flag for early resume so that rtc interrupt get enabled before
parent interrupt and so rtc interrupt get enabled when parent interrupt
handler check for interrupt of device and call the rtc handler if it is
there. This way it will not miss the interrupt.Signed-off-by: Laxman Dewangan

The driver stores the interrupt enable register before going to suspend
and restore in resume. Also it enables alarm before going to suspend.The driver only write the Interrupt enable register for enabling ALARM and
does not enable any other bits. So it is not require to save complete
register and enable ALARM interrupt before suspend and restore in resume.Also ALARM interrupt already enable if alarm is enabled before going to
suspend and hence it is not require to enable explictly in suspend.Removing such above code.

Do not test udelay() for a value less than 10usec when passed a variable
instead of a hard-coded number; there is no way for checkpatch to know the
value of the variable. As it is today, it will complain about variables
with alphanumeric characters plus '_', e.g. foo_bar, but not variables
with other characters, eg. foo->bar.Signed-off-by: Bruce Allan

Change the defautl XZ_DEC_* config symbol to match the configured
architecture. It is perfectly legitimate to support multiple XZ BCJ
filters for different architectures (e.g.: to mount foreign squashfs/xz
compressed filesystems), it is however more natural not to select them all
by default, but only the one matching the configured architecture.Signed-off-by: Florian Fainelli

LP8557 is one of LP855x family device, but it has different register map
and initialization process. To support this device, device specific
configuration is done through the lp855x_device_config structure.Few register definitions are fixed for better readability.
BRIGHTNESS_CTRL -> LP855X_BRIGHTNESS_CTRL
DEVICE_CTRL -> LP855X_DEVICE_CTRL
EEPROM_START -> LP855X_EEPROM_START
EEPROM_END -> LP855X_EEPROM_END
EPROM_START -> LP8556_EPROM_START
EPROM_END -> LP8556_EPROM_ENDAnd LP8557 register definitions are added. New register function,
lp855x_update_bit() is added.Signed-off-by: Milo(Woogyom) Kim

At this moment, LP855x device driver has fixed register configuration.
For example, fixed register addresses and values are set on the device
initialization. But new device of LP855x family, LP8557 has different
register map and initialization sequence. To support new device
architecture, initialization process should be changed.Introduce new structure: lp855x_device_config
=============================================
With lp855x_device_config, device specific features are configurable.
Use configurable function calls and register addresses rather than fixed values.Change on device initialization
===============================
In old LP855x driver architecture, the device initialization was simple.
- Just update the brightness/device control register/ROM area(optional).
In new LP855x driver architecture, two more works are added - pre_init and
post_init.
Those init functions are optional, used for new device LP8557.New device initialization flow: generic sequence
=================================================
1) pre_init_device()
2) update the brightness register
3) update the device control register
4) update ROM area if need
5) post_init_device()Name change
===========
Use generic name 'lp855x_configure()' instead of 'lp855x_init_registers()'.Signed-off-by: Milo(Woogyom) Kim

This is an initial commit of a backlight driver, using step-up DCDC
power supplies on AS3711 PMIC. Only one mode has actually been tested,
several further modes have been implemented "dry," but disabled to avoid
accidental hardware damage. Anyone wishing to use any of those modes
will have to modify the driver.Tested on sh73a0-based kzm9g board. Only one mode has been tested and
is enabled. That mode copies the sample code from the manufacturer.
Deviations from that code proved to be fatal for the hardware...Signed-off-by: Guennadi Liakhovetski
