dm: Use dm_scan_fdt_dev() directly where possible

2016-07-27T20:15:54+00:00

Quite a few places have a bind() method which just calls dm_scan_fdt_dev().
We may as well call dm_scan_fdt_dev() directly. Update the code to do this.

dm: Convert users from dm_scan_fdt_node() to dm_scan_fdt_dev()

2016-07-27T20:15:07+00:00

This new function is more convenient for callers, and handles pre-relocation
situations automatically.

dm: i2c: Add a function to transfer messages

2015-08-06T02:57:51+00:00

Sometimes it is useful to be able to transfer a raw I2C message. This
happens when the chip address needs to be set manually, or when the data to
be sent/received is in another buffer.

Add a function to provide access to this.

single byte register. These are a useful shortcut in many cases.

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.

versions of these functions to avoid conflicts.
