We must not clear global_data even in tests, since the ram_buffer (which
is used by malloc()) will also be lost, and subsequent tests will fail.Zero only the global_data fields that are required for the test to function.

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.Signed-off-by: Przemyslaw Marczak

Take a pass at plumbing errors through to the users of the network stack
Currently only the start() function errors will be returned from
NetLoop(). recv() tends not to have errors, so that is likely not worth
adding. send() certainly can return errors, but this patch does not
attempt to plumb them yet. halt() is not expected to error.Signed-off-by: Joe Hershberger

Both of these values are useful for understanding what is going on, so show
them both.The requested number comes from a device tree alias. The allocated one is

Some uclasses want to set up a device before it is probed. Add a method
for this.An example is with PCI, where a PCI uclass wants to set up its private
data for later use. This allows the device's uclass() method to make calls
whcih use that data (for example, read PCI memory regions from device
tree, set up bus numbers).Signed-off-by: Simon Glass

At present we go through various contortions to store the SPI slave's chip
select in its private data. This only exists when the slave is active so
must be set up when it is probed. Until the device is probed we don't
actually know what chip select it will appear on.However, now that we can support per-child platform data, we can use that
instead. This allows us to set up the chip select when the child is bound,
and avoid the messy contortions.Unfortunately this is a fairly large change and it seems to be difficult to
break it down further.Signed-off-by: Simon Glass

Some buses need to set up their devices before they can be used. This setup
may well be common to all buses in a particular uclass. Support a common
pre-probe method for the uclass, called before any bus devices are probed.Signed-off-by: Simon Glass
Reviewed-by: Masahiro Yamada -
For buses, after a child is bound, allow the uclass to perform some
processing. This can be used to figure out the address of the child (e.g.
the chip select for SPI slaves) so that it is ready to be probed.This avoids bus drivers having to repeat the same process, which really
should be done by the uclass, since it is common.Signed-off-by: Simon Glass

In many cases the per-child private data for a device's children is defined
by the uclass rather than the individual driver. For example, a SPI bus
needs to store information about each of its children, but all SPI drivers
store the same information. It makes sense to allow the uclass to define
this data.If the driver provides a size value for its per-child private data, then use
it. Failng that, fall back to that provided by the uclass.Signed-off-by: Simon Glass

At present we try to use the 'reg' property and device tree aliases to give
devices a sequence number. The 'reg' property is often actually a memory
address, so the sequence numbers thus-obtained are not useful. It would be
better if the devices were just sequentially numbered in that case. In fact
neither I2C nor SPI use this feature, so drop it.Some devices need us to look up an alias to number them within the uclass.
Add a flag to control this, so it is not done unless it is needed.Adjust the tests to test this new behaviour.

In many cases the child platform data for a device's children is defined by
the uclass rather than the individual devices. For example, a SPI bus needs
to know the chip select and speed for each of its children. It makes sense
to allow this information to be defined the SPI uclass rather than each
individual driver.If the device provides a size value for its child platdata, then use it.
Failng that, fall back to that provided by the uclass.Reviewed-by: Masahiro Yamada

For buses it is common for parents to need to know the address of the child
on the bus, the bus speed to use for that child, and other information. This
can be provided in platform data attached to each child.Add driver model support for this, including auto-allocation which can be
requested using a new property to specify the size of the data.Signed-off-by: Simon Glass

When using allocated platform data, allocate it when we bind the device.
This makes it possible to fill in this information before the device is

since platform data exists at bind-time.Signed-off-by: Simon Glass

Rather than assuming that the chip offset length is 1, allow it to be

Add a dm_ prefix to driver model I2C functions so that we can keep the old
ones around.This is a little unfortunate, but on reflection it is too difficult to

At present U-Boot sort-of supports the standard way of reading GPIOs from
device tree nodes, but the support is incomplete, a bit clunky and only
works for GPIO bindings where #gpio-cells is 2.Add new functions to request GPIOs, taking full account of the device
tree binding. These permit requesting a GPIO with a simple call like:gpio_request_by_name(dev, "cd-gpios", 0, &desc, GPIOD_IS_IN);
This will request the GPIO, looking at the device's node which might be
this, for example:cd-gpios = ;
The GPIO will be set to input mode in this case and polarity will be
honoured by the GPIO calls.It is also possible to request and free a list of GPIOs.
