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
