* ACPI: remove private acpica headers from driver filesLin Ming2008-12-3122-42/+0
| | | | | | | External driver files should not include any private acpica headers. Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

* ACPICA: New: acpi_reset interface - write to reset registerBob Moore2008-12-312-0/+39
| | | | | | | | | | | Uses the FADT-defined reset register and reset value. Checks the FADT flags for the reset register supported bit. Supports reset register in memory or I/O space, but not in PCI config space since the host has the information to do it.

* ACPICA: New: acpi_read and acpi_write public interfacesBob Moore2008-12-317-126/+89
| | | | | | | | | | | | | | Changed the acpi_hw_low_level_read and acpi_hw_low_level_write functions to the public acpi_read and acpi_write to allow direct access to ACPI registers. Removed the "width" parameter since the width can be obtained from the input GAS structure. Updated the FADT initialization to setup the GAS structures with the proper widths. Some widths are still hardcoded because many FADTs have incorrect register lengths.

* ACPICA: Add Buffer->String conversion for predefined methodsBob Moore2008-12-303-30/+125
| | | | | | | | | | | | | | For predefined methods (such as _BIF), add automatic conversion for objects that are required to be a String, but a Buffer was found instead. This can happen when reading string battery data from an operation region, because it used to be difficult to convert the data from buffer to string from within the ASL.

| | | | | | | | | | | | | In a fully qualified namepath, allow multiple backslash prefixes. This can happen because of the use of a double-backslash in strings (since backslash is the escape character) causing confusion.

| | | | | | | | | | | | The current implemenation of _OSI within ACPICA only allows other control methods to execute _OSI.

| | | | | | | | | | | | | Add a loop counter to force exit from AML While loops if the count becomes too large. This can occur in poorly written AML when the hardware does not respond within a while loop and the loop does not implement a timeout. The maximum loop count is configurable.

* ACPICA: Optimize execution of AML While loopsBob Moore2008-12-301-4/+25
| | | | | | | | | | | Previously, a control state object was allocated and freed for each execution of the loop. The optimization is to simply reuse the control state for each iteration.

| | | | | | | | | | | | | | | | Split AcpiSetFirmwareWakingVector into two: one for the 32-bit vector, another for the 64-bit vector. This is required because the host OS must setup the wake much differently for each vector (real vs. protected mode, etc.) and the interface should not be deciding which vector to use. Also eliminate the GetFirmwareWakingVector interface, as it served no purpose (only the firmware reads the vector, OS only writes the vector.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the tuner modules were moved to common/tuners, a separate customize option were added for tuners. However, the automatic selection of the tuners were still using the older option. This causes that the automatic selection to fail, if DVB_FE_CUSTOMISE is selected. Also, since those tuners are now under MEDIA_TUNER_CUSTOMIZE menu, if you unset MEDIA_TUNER_CUSTOMIZE, you can't manually select the tuners. This patch fixes this error by replacing DVB_FE_CUSTOMISE by MEDIA_TUNER_CUSTOMIZE on all places were a tuner is selected. The patch were generated by this small script: for i in `find drivers/media -name Kconfig`; do cat $i|perl -ne 's/(MEDIA_TUNER.*)DVB_FE_CUSTOMISE/\1MEDIA_TUNER_CUSTOMIZE/; print $_' >a mv a $i done Also, manually reordered the tuner entries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At some point the Flexcop driver was changed to support newer Flexcop cards. These modifications however broke the detection of Cablestar 2 DVB-C cards. The reason is that the earlier version of the driver used to retry unsuccessful i2c operations. The demodulator of Cablestar 2 cards (stv0297) seems to be very dependent on these retries and adding them back fixes Cablestar detection. This patch restores this behaviour for the CableStar2.
