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 Simon Glass (35): dm: core: Add an ACPI name for the root node acpi: Add a function to get a device path and scope acpi: Add a way to check device status irq: Add a method to convert an interrupt to ACPI acpi: Support generation of ACPI code acpi: Support generation of interrupt descriptor gpio: Add a method to convert a GPIO to ACPI acpi: Support string output acpi: Support generation of GPIO descriptor acpi: Support generation of a GPIO/irq for a device acpi: Support generation of I2C descriptor acpi: Support generation of SPI descriptor acpigen: Support writing a length acpigen: Support writing a package acpi: Support writing an integer acpi: Support writing a string acpi: Support writing a name acpi: Support writing a UUID acpi: Support writing Device Properties objects via _DSD acpi: Support writing a GPIO acpi: Support copying properties from device tree to ACPI acpi: Add support for various misc ACPI opcodes acpi: Add support for writing a Power Resource acpi: Add support for writing a GPIO power sequence acpi: Add support for a generic power sequence acpi: Add support for SSDT generation x86: acpi: Move MADT down a bit acpi: Record the items added to SSDT acpi: Support ordering SSDT data by device x86: Allow devices to write an SSDT acpi: Add support for DSDT generation x86: Allow devices to write to DSDT pci: Avoid a crash in device_is_on_pci_bus() dm: acpi: Enhance acpi_get_name() acpi: Add an acpi split command arch/sandbox/dts/test.dts | 14 +- arch/x86/lib/acpi_table.c | 75 ++- cmd/acpi.c | 15 +- doc/device-tree-bindings/chosen.txt | 9 + doc/device-tree-bindings/device.txt | 13 + drivers/core/acpi.c | 207 ++++++- drivers/core/root.c | 13 + drivers/gpio/gpio-uclass.c | 21 + drivers/gpio/sandbox.c | 78 +++ drivers/i2c/sandbox_i2c.c | 1 + drivers/misc/irq-uclass.c | 18 +- drivers/misc/irq_sandbox.c | 16 + drivers/rtc/sandbox_rtc.c | 11 + drivers/spi/sandbox_spi.c | 1 + include/acpi/acpi_device.h | 400 +++++++++++++ include/acpi/acpi_dp.h | 283 +++++++++ include/acpi/acpi_table.h | 6 + include/acpi/acpigen.h | 347 +++++++++++ include/asm-generic/gpio.h | 27 + include/dm/acpi.h | 63 ++ include/dm/device.h | 2 +- include/irq.h | 43 ++ include/spi.h | 4 +- include/test/ut.h | 17 + lib/acpi/Makefile | 3 + lib/acpi/acpi_device.c | 808 ++++++++++++++++++++++++++ lib/acpi/acpi_dp.c | 395 +++++++++++++ lib/acpi/acpigen.c | 475 +++++++++++++++ test/dm/Makefile | 2 + test/dm/acpi.c | 277 ++++++++- test/dm/acpi_dp.c | 510 ++++++++++++++++ test/dm/acpigen.c | 861 ++++++++++++++++++++++++++++ test/dm/gpio.c | 62 ++ test/dm/irq.c | 23 + test/dm/pci.c | 14 + 35 files changed, 5081 insertions(+), 33 deletions(-) create mode 100644 include/acpi/acpi_device.h create mode 100644 include/acpi/acpi_dp.h create mode 100644 include/acpi/acpigen.h create mode 100644 lib/acpi/acpi_device.c create mode 100644 lib/acpi/acpi_dp.c create mode 100644 lib/acpi/acpigen.c create mode 100644 test/dm/acpi_dp.c create mode 100644 test/dm/acpigen.c -- 2.26.2.303.gf8c07b1a785-goog
