platform / x86 / PM: Fix unused function warnings for CONFIG_PM_SLEEP

2012-08-10T12:29:43+00:00

According to compiler warnings, quite some suspend/resume functions
in platform x86 drivers are not used for CONFIG_PM_SLEEP unset, so
add #ifdefs to prevent them from being built in that case.

Platform: OLPC: move global variables into priv struct

2012-08-01T03:27:31+00:00

Populate olpc_ec_priv with variables that were previously global.  This
makes things a tad bit clearer, IMO.

Platform: OLPC: move debugfs support from x86 EC driver

2012-08-01T03:27:31+00:00

There's nothing about the debugfs interface for the EC driver that is
architecture-specific, so move it into the arch-independent driver.

The code is mostly unchanged with the exception of renamed variables, coding
style changes, and API updates.

x86: OLPC: switch over to using new EC driver on x86

2012-08-01T03:27:30+00:00

This uses the new EC driver framework in drivers/platform/olpc.  The
XO-1 and XO-1.5-specific code is still in arch/x86, but the generic stuff
(including a new workqueue; no more running EC commands with IRQs disabled!)
can be shared with other architectures.

Platform: OLPC: add a suspended flag to the EC driver

2012-08-01T03:27:30+00:00

A problem we've noticed on XO-1.75 is when we suspend in the middle of
an EC command.  Don't allow that.

In the process, create a private object for the generic EC driver to use;
we have a framework for passing around a struct, use that rather than a
proliferation of global variables.

Platform: OLPC: turn EC driver into a platform_driver

2012-08-01T03:27:30+00:00

The 1.75-based OLPC EC driver already does this; let's do it for all EC
drivers.  This gives us nice suspend/resume hooks, amongst other things.

We want to run the EC's suspend hooks later than other drivers (which may
be setting wakeup masks or be running EC commands).  We also want to run
the EC's resume hooks earlier than other drivers (which may want to run EC
commands).

Platform: OLPC: allow EC cmd to be overridden, and create a workqueue to call it

2012-08-01T03:27:30+00:00

This provides a new API allows different OLPC architectures to override the
EC driver.  x86 and ARM OLPC machines use completely different EC backends.

The olpc_ec_cmd is synchronous, and waits for the workqueue to send the
command to the EC.  Multiple callers can run olpc_ec_cmd() at once, and
they will by serialized and sleep while only one executes on the EC at a time.

We don't provide an unregister function, as that doesn't make sense within
the context of OLPC machines - there's only ever 1 EC, it's critical to
functionality, and it certainly not hotpluggable.

drivers: OLPC: update various drivers to include olpc-ec.h

2012-08-01T03:27:29+00:00

Switch over to using olpc-ec.h in multiple steps, so as not to break builds.
This covers every driver that calls olpc_ec_cmd().

Platform: OLPC: add a stub to drivers/platform/ for the OLPC EC driver

2012-08-01T03:27:29+00:00

The OLPC EC driver has outgrown arch/x86/platform/.  It's time to both
share common code amongst different architectures, as well as move it out
of arch/x86/.  The XO-1.75 is ARM-based, and the EC driver shares a lot of
code with the x86 code.
