2014-09-25ACPICA: Update to GPIO region handler interface.Bob Moore1-0/+2
Changes to correct several GPIO issues: 1) The update_rule in a GPIO field definition is now ignored; a read-modify-write operation is never performed for GPIO fields. (Internally, this means that the field assembly/disassembly code is completely bypassed for GPIO.) 2) The Address parameter passed to a GPIO region handler is now the bit offset of the field from a previous Connection() operator. Thus, it becomes a "Pin Number Index" into the Connection() resource descriptor. 3) The bit_width parameter passed to a GPIO region handler is now the exact bit width of the GPIO field. Thus, it can be interpreted as "number of pins". Overall, we can now say that the region handler interface to GPIO handlers is a raw "bit/pin" addressed interface, not a byte-addressed interface like the system_memory handler interface.

2010-10-01ACPICA: Revert "Revert "Enable multi-byte EC transfersBob Moore1-23/+22
This reverts commit f23b9c7(http://git.moblin.org/cgit.cgi/acpica/commit/?id=f23b9c7) The problem with this change was determined to be a problem with the FreeBSD host OSL (OS services layer), not with this patch itself. Therefore, re-introducing this change into the main ACPICA code.

2010-04-16ACPI: EC: Limit burst to 64 bitsAlexey Starikovskiy1-6/+11
access_bit_width field is u8 in ACPICA, thus 256 value written to it becomes 0, causing divide by zero later. Proper fix would be to remove access_bit_width at all, just because we already have access_byte_width, which is access_bit_width / 8. Limit access width to 64 bit for now. https://bugzilla.kernel.org/show_bug.cgi?id=15749 fixes regression caused by the fix for: https://bugzilla.kernel.org/show_bug.cgi?id=14667 Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>
