2021-12-06acpi: Add #define for Mutex "no timeout" valueTim Wawrzynczak
Some acpigen code may use mutexes, and it is a common idiom to pass a value for the Timeout field of 0xffff, which is interpreted by OSPM to mean "no timeout". Therefore add a macro for this value.

2021-10-21acpigen,soc/amd,cpu/intel: rework static DWORD for CPPC tableMichael Niewöhner
Some elements in the ACPI CPPC table allow static DWORDs. Instead of using a fake register resource, use a tagged union with the two types "register" and "DWORD" and respective macros for CPPC table entries. Test: dumped SSDT before and after do not differ.

2021-03-22acpi/acpigen.h: Add more intuitive AML package closing functionsJakub Czapiga
Until now every AML package had to be closed using acpigen_pop_len(). This commit introduces set of package closing functions corresponding with their opening function names. For example acpigen_write_if() opens if-statement package, acpigen_write_if_end() closes it. Now acpigen_write_else() closes previously opened acpigen_write_if(), so acpigen_pop_len() is not required before it.
