36cdfbe0db Don't retry to post a command if the EC doesn't answer for a second. 
It seems to create more issues than it fixes. Try to defend against
lost/late GPEs by using a callout to kick the state machine regulary.
Add some notes about the purpose and working of the driver.

7d42ba2288 Don't be quite so aggressive in EcWaitEvent; makes acpiec work on the 
Sony VAIO VGN-N250E, and possibly others.

bd130aba8f Add ACPI ECDT (Embedded Controller Description Table) support. 
This will enable usage of EC in early stage of ACPI initialization.

9a34eb3d5a - fix deadlocks due to using lock_status() from interrupt context. 
- process pending queries in EcUnlock() to close a race window.
  now there's no need to do polling for EcQuery().
- reorder inline functions and other prototypes so that
  the formers can get needed prototypes.
- add missing prototypes.

84795bd3fd * now the size of ACPI_DEVICE_INFO is variable: 
it can now accomodate multiple _CIDs
  sizeof(ACPI_DEVICE_INFO) should not be used
* make ad_devinfo member in acpi_devnode a pointer
* implement acpi_match_hid() to simplify matching devices;
  _CIDs are also taken into account now as well as _HID

fec4c11f9e Catch up with ABI changes in ACPI-CA. Some additional changes to acpi_bat to 
set the VALID bits correctly, so we don't report garbage for missing batteries.

e077f7a7d9 - add acpi_acquire_global_lock()/acpi_release_global_lock()/ 
acpi_is_global_locked() functions.
  AcpiGlobalLock() API should be used to acquire lock between BIOS and OS.
  This API cannot be used to lock between threads of the OS side,
  because this function immediately returns if the lock is already acquired
  by the OS.  c.f. AcpiEvAcquireGlobalLock()@evmisc.c

- make sure that acpiec driver uses above functions.

- use ACPI_ALLOCATE_BUFFER instead of twice calls of AcpiEvaluateObject(),
  in acpi_eval_string()/acpi_eval_struct().
  Twice AcpiEvaluateObject() calls may cause twice side effects
  to ACPI machine / hardware and this may be wrong in some cases.
