acpi: Export functions to write sized values

2020-07-17T06:32:24Z

At present only acpigen_write_integer() is exported for use by other code. But in some cases it is useful to call the specific function depending on the size of the value. Export these functions and add a test. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng [bmeng: Fix the "new blank line at EOF" warning] Signed-off-by: Bin Meng

dm: acpi: Enhance acpi_get_name()

2020-07-17T06:32:24Z

For many device types it is possible to figure out the name just by looking at its uclass or parent. Add a function to handle this, since it allows us to cover the vast majority of cases automatically. However it is sometimes impossible to figure out an ACPI name for a device just by looking at its uclass. For example a touch device may have a vendor-specific name. Add a new "acpi,name" property to allow a custom name to be created. With this new feature we can drop the get_name() methods in the sandbox I2C and SPI drivers. They were only added for testing purposes. Update the tests to use the new values. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng

acpi: Add support for a generic power sequence

2020-07-17T06:32:24Z

Add a way for devices to enable and disable themselves using ACPI code that updates GPIOs. This takes several timing parameters and supports enable, reset and stop. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng

acpi: Add support for writing a GPIO power sequence

2020-07-17T06:32:24Z

Power to some devices is controlled by GPIOs. Add a way to generate ACPI code to enable and disable a GPIO so that this can be handled within an ACPI method. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng

acpi: Add support for writing a Power Resource

2020-07-17T06:32:24Z

These are used in ACPI to disable power to various pats of the system when in sleep. Add a way to create a power resource, with the caller finishing off the details. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng

acpi: Add support for various misc ACPI opcodes

2020-07-17T06:32:24Z
