This is split from the original series in an attempt to get things applied
in chunks.

Unfortunately some test failures were introduced due to a badly handled
conflict with an upstream patch. v8 fixes that.

Changes in v8:
- Fix tests on sandbox
- Fix test failures introduced by rebasing on top of master

Changes in v7:
- Rebase to master

Changes in v5:
- Drop bisectability changes

Changes in v4:
- Put 'interrupts-extended' property on one line
- Rename acpi-probed to linux,probed
- Note that linux,probed is an out-of-tree feature
- Separate out the log newline
- Update comment in acpi_inc_align() to show the alignment
- Put back cast on table_compute_checksum()
- Rename list_fact() to list_fadt()
- Add a comment to dump_hdr()

Changes in v3:
- Drop mention of PRIC
- Rename acpi,desc to acpi,ddn
- Correct description of acpi,probed
- Drop hid-descr-addr
- Just add the device.txt binding file in this patch
- Change the example to ELAN
- Add a pointer to information about acpi,compatible
- Rename acpi_align_large() to acpi_align64()
- Fix 'RSDP' typo
- Fix 'XDST' typo
- Move acpi_align_large() out of dm_test_acpi_setup_base_tables()
- Beef up the comment explaining how the unaligned address is used

Changes in v2:
- Fix definition of HID
- Infer hid-over-i2c CID value
- Add the hid-over-i2c binding document
- Drop definition of ACPI_TABLE_CREATOR
- Make _acpi_write_dev_tables() static and switch argument order
- Generalise the ACPI function recursion with acpi_recurse_method()

Simon Glass (9):
  acpi: Add a binding for ACPI settings in the device tree
  acpi: Add a method to write tables for a device
  acpi: Convert part of acpi_table to use acpi_ctx
  x86: Allow devices to write ACPI tables
  acpi: Drop code for missing XSDT from acpi_write_rsdp()
  acpi: Move acpi_add_table() to generic code
  acpi: Put table-setup code in its own function
  acpi: Move the xsdt pointer to acpi_ctx
  acpi: Add an acpi command
