dm: i2c: Add compatibility functions for dm_i2c_reg_read/write()

2015-06-11T01:26:54+00:00

Add the legacy i2c_reg_read/write() functions to the compatibility layer
so that they can be used when CONFIG_DM_I2C_COMPAT is defined.

dm: i2c: Add a function to find out the chip offset length

2015-05-15T00:49:33+00:00

We can currently set this but there is no API function to get it. Add one.

dm: i2c: Add an explicit test mode to the sandbox I2C driver

2015-05-06T02:58:19+00:00

At present this driver has a few test features. They are needed for running
the driver model unit tests but are confusing and unnecessary if using
sandbox at the command line. Add a flag to enable the test mode, and don't
enable it by default.

dm: i2c: Add functions to read and write a register

2015-05-06T02:58:19+00:00

Add driver model versions of the legacy functions to read and write a
single byte register. These are a useful shortcut in many cases.

dm: core: Add dev_get_uclass_priv() to access uclass private data

2015-04-17T01:27:42+00:00

Add a convenience function to access the private data that a uclass stores
for each of its devices. Convert over most existing uses for consistency
and to provide an example for others.

dm: i2c: Make API accessible even without CONFIG_DM

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

Make the driver model I2C API available always, even if driver model
is not enabled. This allows for a 'soft' switch-over, where drivers can
use the new structures in code which is compiled but not yet used. This
makes migration easier in some cases.

Fix up the existing drivers which define their own 'struct i2c_msg'.

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: i2c: Add two more I2C init functions to the compatibility layer

2015-01-30T00:10:01+00:00

These functions are useful in case the board calls them. Also fix a missing
parameter caused by applying the wrong patch (actually I failed to send v2
and applied v1 by mistake).

dm: i2c: Move slave details to child platdata

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

At present we go through various contortions to store the I2C's chip
address in its private data. This only exists when the chip is active so
must be set up when it is probed. Until the device is probed we don't
actually record what address 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 address 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: i2c: Provide an offset length parameter where needed

2015-01-30T00:09:53+00:00

Rather than assuming that the chip offset length is 1, allow it to be
provided. This allows chips that don't use the default offset length to
be used (at present they are only supported by the command line 'i2c'
command which sets the offset length explicitly).
