dm: Implement a CPU uclass

2015-04-30T03:02:33+00:00

It is useful to be able to keep track of the available CPUs in a multi-CPU
system. This uclass is mostly intended for use with SMP systems.

The uclass provides methods for getting basic information about each CPU.

dm: core: Add a function to bind a driver for a device tree node

2015-04-30T03:02:32+00:00

Some device tree nodes do not have compatible strings but do require
drivers. This is pretty rare, and somewhat unfortunate. Add a function
to permit creation of a driver for any device tree node.

dm: core: Remove unbind operations when not required

2015-04-23T15:05:52+00:00

The CONFIG_DM_DEVICE_REMOVE option takes out code related to removing
devices. It should also remove the 'unbind' code since if we cannot
remove we probably don't need to unbind.

dm: core: precise comments for get/find device by name

2015-04-22T17:03:16+00:00

The functions:
- uclass_find_device_by_name()
- uclass_get_device_by_name()
searches the required device for the exactly given name.
This patch, presice this fact for both function's comments.

dm: core: remove type 'static' of function uclass_get_device_tail()

2015-04-22T17:03:15+00:00

Uclass API provides a few functions for get/find the device.
To provide a complete function set of uclass-internal functions,
for use by the drivers, the function uclass_get_device_tail()
should be non-static.

dm: core: device: add function: dev_get_uclass_name()

2015-04-22T17:03:15+00:00

This commit extends the driver model device's API by function:
- dev_get_uclass_name()

And this function returns the device's uclass driver name if:
- given dev pointer, is non_NULL
otherwise, the NULL pointer is returned.

dm: core: device: add function: dev_get_driver_ops()

2015-04-22T17:03:15+00:00

This commit extends the driver model device's API by function:
- dev_get_driver_ops()

And this function returns the device's driver's operations if given:
- dev pointer, is non-NULL
- dev->driver->ops pointer, is non-NULL
in other case the, the NULL pointer is returned.

dm: core: uclass: add function: uclass_get_device_by_name()

2015-04-22T17:03:15+00:00

This commit extends the driver model uclass's API by function:
- uclass_get_device_by_name()

And this function returns the device if:
- uclass with given ID, exists,
- device with exactly given name(dev->name), exists,
- device probe, doesn't return an error.

The returned device is activated and ready to use.

Note:
This function returns the first device, which name is equal
to the given one. This means, that using this function you must
assume, that the device name is unique in the given uclass's ID
device list.

dm: core: uclass: add function: uclass_find_device_by_name()

2015-04-22T17:03:15+00:00

This commit extends the driver model uclass's API by function:
- uclass_find_device_by_name()

And this function returns the device if:
- uclass with given ID, exists,
- device with exactly given name(dev->name), exists.

The returned device is not activated - need to be probed before use.

Note:
This function returns the first device, which name is equal
to the given one. This means, that using this function you must
assume, that the device name is unique in the given uclass's ID
device list.

uclass-internal.h: cleanup - move the uclass_find_device_by_seq()
declaration and description, near the other uclass_find*() functions.

dm: test: Add tests for device's uclass platform data

2015-04-22T17:03:14+00:00

This test introduces new test structure type:dm_test_perdev_uc_pdata.
The structure consists of three int values only. For the test purposes,
three pattern values are defined by enum, starting with TEST_UC_PDATA_INTVAL1.

This commit adds two test cases for uclass platform data:
- Test: dm_test_autobind_uclass_pdata_alloc - this tests if:
  * uclass driver sets: .per_device_platdata_auto_alloc_size field
  * the devices's: dev->uclass_platdata is non-NULL

- Test: dm_test_autobind_uclass_pdata_valid - this tests:
  * if the devices's: dev->uclass_platdata is non-NULL
  * the structure of type 'dm_test_perdev_uc_pdata' allocated at address
    pointed by dev->uclass_platdata. Each structure field, should be equal
    to proper pattern data, starting from .intval1 == TEST_UC_PDATA_INTVAL1.
