This output can then be used by tests to detect device probe failures. In order to filter the compatibles down to only ones that will match to a driver, the following is considered: - A compatible needs to show up in a driver's of_match_table for it to be matched to a driver - Compatibles that are used in both of_match_table and OF_DECLARE type macros can't be expected to match to a driver and so are ignored. One exception is CLK_OF_DECLARE_DRIVER, since it indicates that a driver will also later probe, so compatibles in this macro are not ignored. Signed-off-by: NĂ­colas F. R. A.
