dm: core: Change syscon to use helper function

2020-02-07T14:41:24+00:00

Now that we have uclass_first_device_drvdata(), use it from syscon to
reduce code duplication.

dm: core: Add a function to find a device by drvdata

2020-02-07T14:41:24+00:00

It is sometimes useful to find a device in a uclass using only its driver
data. The driver data often indicates the 'subtype' of the device, e,g,
via its compatible string.

Add a function to handle this.

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

dm: core: Require users of devres to include the header

2020-02-06T02:33:46+00:00

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

cmd: Add command to dump drivers and compatible strings

2020-02-06T02:33:46+00:00

This adds a subcommand to dm to dump out what drivers are installed, and their
compatible strings. I have found this useful in ensuring that I have the correct
drivers compiled, and that I have put in the correct compatible strings.

dm: core: Drop uclass_find_next_free_req_seq() conditions

2020-02-06T02:33:45+00:00

These conditions are not needed and just reduce build coverage. Drop them.

dm: core: Add a way to iterate through children, probing each

2020-02-06T02:33:45+00:00

It is sometimes useful to process all children, making sure they are
probed first. Add functions to help with this and a macro to make it more
convenient.

dm: core: Add a way to read platdata for all child devices

2020-02-06T02:33:45+00:00

When generating ACPI tables we need to make sure that all devices have
read their platform data, so that they can generate the tables correctly.

Rather than adding this code in ACPI, create a core function to handle it.

dm: core: Add ofnode_get_chosen_prop()

2020-02-06T02:33:45+00:00

Add a function to read a property from the chosen node, providing access
to its length. Update ofnode_get_chosen_string() to make use of it.
