eb9ef5fee7 dm: Use an explicit expect value in core tests
Rather than reusing the 'reg' property, use an explicit property for the
expected ping value used in testing.

4af5b1445c dm: Use '*' to indicate a device is activated
Make both dm enumeration commands support showing whether a driver is active
or not, and use a consistent indicator (an asterisk).

184b1b7175 dm: Fix printf() strings in the 'dm' command
The values here are int, but the map_to_sysmem() call can return a long.
Add a cast to deal with this.

b6a49a7ae7 dm: Allow driver model tests only for sandbox
The GPIO tests require the sandbox GPIO driver, so cannot be run on other
platforms. Similarly for the 'dm test' command.

ae7f451308 dm: Rename struct device_id to udevice_id
It is best to avoid having any occurence of 'struct device' in driver
model, so rename to achieve this.

54c5d08a09 dm: rename device struct to udevice
using UBI and DM together leads in compiler error, as
both define a "struct device", so rename "struct device"
in include/dm/device.h to "struct udevice", as we use
linux code (MTD/UBI/UBIFS some USB code,...) and cannot
change the linux "struct device"

96495d90fe dm: Add GPIO support and tests
Add driver model support for GPIOs. Since existing GPIO drivers do not use
driver model, this feature must be enabled by CONFIG_DM_GPIO. After all
GPO drivers are converted over we can perhaps remove this config.

Tests are provided for the sandbox implementation, and are a sufficient
sanity check for basic operation.

The GPIO uclass understands the concept of named banks of GPIOs, with each
GPIO device providing a single bank. Within each bank the GPIOs are numbered
using an offset from 0 to n-1. For example a bank named 'b' with 20
offsets will provide GPIOs named b0 to b19.

Anonymous GPIO banks are also supported, and are just numbered without any
prefix.

Each time a GPIO driver is added to the uclass, the GPIOs are renumbered
accordinging, so there is always a global GPIO numbering order.

0681195977 dm: Add a 'dm' command for testing
This command is not required for driver model operation, but can be useful
for testing. It provides simple dumps of internal data structures.

2e7d35d2a6 dm: Add basic tests
Add some tests of driver model functionality. Coverage includes:

- basic init
- binding of drivers to devices using platform_data
- automatic probing of devices when referenced
- availability of platform data to devices
- lifecycle from bind to probe to remove to unbind
- renumbering within a uclass when devices are probed/removed
- calling driver-defined operations
- deactivation of drivers when removed
- memory leak across creation and destruction of drivers/uclasses
- uclass init/destroy methods
- automatic probe/remove of children/parents when needed

This function is enabled for sandbox, using CONFIG_DM_TEST.
