dm: dump.c: Fix segfault when entry->of_match is NULL

2020-04-09T21:12:34+00:00

Currently, dm drivers command produces a segfault:
=> dm drivers
Driver                Compatible
--------------------------------
Segmentation fault (core dumped)

This is caused by a NULL pointer dereference of entry->of_match.
Add a check to prevent this.

dm: core: Add a flag for power domain control on device removal

2020-03-03T02:47:38+00:00

In various cases a power domain must stay enabled after device
removal when booting OS (i.e. serial debug console or display).
Add a flag to selectively skip switching off a power domain.

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

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