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: Drop the inclusion of linux/compat.h in dm.h

2020-02-06T04:48:22+00:00

Most files don't need this header and it pulls in quite of lots of stuff,
malloc() in particular. Drop it.

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.

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: Use const where possible in device.h

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

Update this header file to use const devices where possible, to permit
callers to also use const.

dm: devres: Create a new devres header file

2020-01-07T23:02:38+00:00

At present these functions are lumped in with the core device functions.
They have their own #ifdef to control their availability, so it seems
better to split them out.

Move them into their own header file.

dm: core: Add a new flag to track platform data

2020-01-07T23:02:38+00:00

We want to avoid allocating platform data twice. This could happen if
device_probe() is called after device_ofdata_to_platdata() for the same
device.

Add a flag to track whether device_ofdata_to_platdata() has been called on
a device. Check the flag to make sure it doesn't happen twice, and clear
the flag when the data is freed.

This flag is missing a comment. Add one.
