dm: i2c: Add a dm_ prefix to driver model bus speed functions

2015-02-12T17:35:33+00:00

As with i2c_read() and i2c_write(), add a dm_ prefix to the driver model
versions of these functions to avoid conflicts.

dm: spi: Move slave details to child platdata

2015-01-30T00:09:56+00:00

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.

dm: core: Allow uclass to set up a device's child before it is probed

2015-01-30T00:09:56+00:00

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.

dm: core: Allow the uclass to set up a device's child after binding

2015-01-30T00:09:56+00:00

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.

dm: core: Allow uclasses to specify private data for a device's children

2015-01-30T00:09:55+00:00

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.

dm: core: Add a flag to control sequence numbering

2015-01-30T00:09:55+00:00

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.

dm: core: Add a function to get a device's uclass ID

This is useful to check which uclass a device is in.

dm: core: Add a post_bind method for parents

2015-01-30T00:09:55+00:00

Allow parent drivers to be called when a new child is bound to them. This
allows a bus to set up information it needs for that child.
