x86: Add wake sources for the acpi_gpe driver

2020-09-25T03:27:15+00:00

Some devices can wake the system from sleep, e.g opening the lid on a clamshell or moving a USB mouse. Add a wake to specify this for USB devices and add the settings for Apollo Lake. Signed-off-by: Simon Glass

dm: core: Add a way of overriding the ACPI device path

2020-07-17T06:32:24+00:00

Some devices such as GPIO need to override the normal path that would be generated by driver model. Add a device-tree property for this. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Reviewed-by: Wolfgang Wallner

dm: acpi: Enhance acpi_get_name()

2020-07-17T06:32:24+00:00

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 a binding for ACPI settings in the device tree

2020-04-30T09:16:12+00:00

Devices need to report various identifiers in the ACPI tables. Rather than hard-coding these in drivers it is typically better to put them in the device tree. Add a binding file to describe this. Signed-off-by: Simon Glass
