dm: core: Add a function to find the first inactive child

2018-10-09T10:40:27+00:00

Some devices have children and want to press an existing inactive child
into service when needed. Add a function to help with this.

dm: core: Update some functions to use const

2018-10-09T10:40:27+00:00

Quite a few functions do not actually modify the device that is passed in.
Update the function signatures to reflect that.

dm: core: Alloc uclass-private data to be cache-aligned

2018-10-09T10:40:27+00:00

There is no reason why this feature should not be supported for uclass-
private data. Update the code accordingly.

core: Add dev_{disable,enable}_by_path

2018-09-29T17:49:35+00:00

We cannot use device structures to disable devices, since getting
them with the API functions would bind and activate the device, which
would fail if the underlying device does not exist.

dm: convert device_get_global_by_of_offset() to device_get_global_by_ofnode()

2018-08-21T14:21:37+00:00

Also add device_find_global_by_ofnode() that also find a device based on
the OF node, but doesn't probe the device.

dm: core: Add a way to bind a device by ofnode

2018-07-09T15:11:00+00:00

Add a new device_bind_ofnode() function which can bind a device given its
ofnode. This allows binding devices more easily with livetree nodes.

dm: ofnode: add ofnode_device_is_compatible() helper

2018-05-07T19:49:51+00:00

device_is_compatible() takes udevice, but there is no such a helper
that takes ofnode.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

clk: implement clk_set_defaults()

2018-01-28T16:12:36+00:00

Linux uses the properties 'assigned-clocks', 'assigned-clock-parents'
and 'assigned-clock-rates' to configure the clock subsystem for use
with various peripheral nodes.

This implements clk_set_defaults() and hooks it up with the general
device probibin in drivers/core/device.c: when a new device is probed,
clk_set_defaults() will be called for it and will process the
properties mentioned above.

Note that this functionality is designed to fail gracefully (i.e. if a
clock-driver does not implement set_parent(), we simply accept this
and ignore the error) as not to break existing board-support.

Cover-letter:
clk: support assigned-clock, assigned-clock-parents, assigned-clock-rates

For various peripherals on Rockchip SoCs (e.g. for the Ethernet GMAC),
the parent-clock needs to be set via the DTS.  This adds the required
plumbing and implements the GMAC case for the RK3399.
