NOTE: I have resent this as v1 to avoid confusion
This is split from the original series in an attempt to get things applied
in chunks.
This part includes:
- writing basic ACPI code for integers, strings, names, packages
- writing descriptors for GPIO, I2C, interrupts, SPI
- writing code to enable/disable ACPI peripherals via GPIOs
- writing SSDT and DSDT tables
- additional ways to determine ACPI device names
Much of this code is taken from coreboot and I have tried to avoid
changing the original code for no reason. Changes include:
- splitting the acpi_dp functions into their own file
- adding tests
- adding (lots of) comments
- using a context pointer instead of global variables
- tidying up some code where couldn't resist (e.g. acpigen_emit_namestring())
Changes in v1:
- Capitalise ACPI_OPS_PTR
- Split into more patches for review
- Add tests
- Fix 'the an' typo
- Move header definitions into this patch
- Update sandbox driver slightly for testing
- Switch parameter order of _acpi_fill_ssdt() and make it static
- Fix 'sentinal' and 'METHOD_FILL_SDDT' typos
- Correct the commit subject
- Generalise the ACPI function recursion with acpi_recurse_method()
- Generalise the ACPI function recursion with acpi_recurse_method()
- Use OEM_TABLE_ID instead of ACPI_TABLE_CREATOR
- Update ACPI_DSTATUS enum
- Generalise the ACPI function recursion with acpi_recurse_method()
- Use acpi,ddn instead of acpi,desc
- Rename to acpi_device_infer_name()
- Update newly created sandbox tests
