Move backlight support out of pcf50633 driver. backlight
support now uses corgibl aka generic backlight support.
Set
CONFIG_BACKLIGHT_CORGI=y to use it.
|
|
Improves ADC access interface in pcf50633 driver.
|
|
Specify regulator constraints for gta02. For now, constraints for only
the current used devices are specified.
|
|
Modify pcf50633 driver to use the new regulator API.
|
|
Eliminate pcf50633_global and hence make pcf50633.c work with
multiple devices. pcf50633 is no longer a paltform device, but
an i2c device.
|
|
Setting the current limit directly and enabling the charger
isn't anyone's business except pcf50633 driver itself, so these
two functions should not be exported and become static.

Subject: [PATCH] [janitor] Make checkpatch happy on the header files

pcf50633.c shouldn't know GTAxx at all. Move to using a
platform callback to allow definition of platform devices
with pcf50633 as parent device (good for enforcing suspend /
resume ordering). Remove all code references to GTAxx from
the sources (one string left for compatability).

pcf50633 needs to take responsibility for managing current limit
changes asycnhrnously, ie, from USB stack enumeration. It's a feature of
pcf50633 not mach-gta02.c, and we can do better with taking care about
keeping it from firing at a bad time in there too.

After protecting pcf50633 read and write primitives against
operation after suspend or before resume (by blowing a
stack_trace()) I saw glamo-mci was trying to use pcf50633
at these bad times on its own suspend and resume. Since that
part was already done via platform callback, I added an
export in pcf50633 that tells you if it is ready or busy,
and used it to defer (resume power on case) or ignore
(suspend power off case, since pcf50633 already did it)
the mci power call.

Adds the resume callback stuff to glamo, then changes
jbt6k74 to no longer use a sleeping workqueue, but to
make its resume actions dependent on pcf50633 and
glamo resume (for backlight and communication to LCM
respectively)

Adds resume dependency support to pcf50633

Currently we are willing to wake from sleep from
pcf50633 interrupts we don't actually do anything about
even when we wake (somewhat puzzled).
Let's disable some of these wake sources.

If you have U-Boot with uboot-add-find-wake-reason.patch, this
patch will get you a wake reason report from
cat /sys/devices/platform/neo1973-resume.0/resume_reason
it looks like this:

EINT02_BLUETOOTH

This shows a problem, false wake from suspend due to battery full

This patch improves the smoothness of suspend and resume action.
Taking out CONFIG_PM_DEBUG allows much more rapid resume (the low level
serial traffic appears to be synchronous)
Added a platform callback in jbt driver and support in pcf50633 so we
can defer bringing up the backlight until the LCM is able to process
video again (which must happen after the glamo is up and producing
video beacuse the LCM is hooked to glamo SPI)
GTA01 should not be affected by all this as the callback will default
to null and it is on pcf50606

Modify GTA02 power manager for bluetooth.
1. Default power value isn't correct. Now we set pcf50633 LDO4 to 3.2 voltage.
2. Separate GTA01 and GTA02 source code.
3. Add pcf50633 API for enable register.

Moved shared PMU code from pcf50606.h and pcf50633.h (which prevented inclusion
of both at the same time) to pcf506xx.h
- include/linux/pcf50606.h (struct pmu_voltage_rail, enum pmu_event, pmu_cb):
moved to pcf506xx.h
- include/linux/pcf50633.h (struct pmu_voltage_rail, enum pmu_event, pmu_cb):
moved to pcf506xx.h
