This new command can dump all device resources associated to each device. The fields in every line shows: - The address of the resource - The size of the resource - The name of the release function - The stage in which the resource has been acquired (BIND/PROBE) Currently, there is no driver using devres, but if such drivers are implemented, the output of this command should look like this: => dm devres - root_driver - soc - extbus - serial@54006800 bfb541e8 (8 byte) devm_kmalloc_release BIND bfb54440 (4 byte) devm_kmalloc_release PROBE bfb54460 (4 byte) devm_kmalloc_release PROBE - serial@54006900 bfb54270 (8 byte) devm_kmalloc_release BIND - gpio@55000000 - i2c@58780000 bfb5bce8 (12 byte) devm_kmalloc_release PROBE bfb5bd10 (4 byte) devm_kmalloc_release PROBE - eeprom bfb54418 (12 byte) devm_kmalloc_release BIND Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Simon Glass <sjg@chromium.org>
