Hi, Basically the helper is just a generic version of the function of_device_is_compatible() that should work also with ACPI and software nodes. As the first user for the helper, I'm converting in this series the USB role switch code to expect the "compatible" property to have the value "usb-role-switch" instead of expecting a boolean property named "usb-role-switch". I'm doing the same for the USB Type-C mux code. thanks, Heikki Krogerus (3): device property: Add fwnode_is_compatible() and device_is_compatible() helpers usb: roles: Use the "compatible" property instead of a boolean property usb: typec: mux: Use the "compatible" property instead of a boolean property drivers/base/property.c | 35 +++++++++++++++++++++++++++++++++++ drivers/usb/roles/class.c | 2 +- drivers/usb/typec/mux.c | 8 ++------ include/linux/property.h | 3 +++ 4 files changed, 41 insertions(+), 7 deletions(-) -- 2.20.1
