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.

dm: core: Rename of_device_is_compatible()

2017-06-01T13:03:06+00:00

The of_ prefix conflicts with the livetree version of this function.
Rename it to avoid problems when we add livetree support.

dm: Rename dev_addr..() functions

2017-06-01T13:03:01+00:00

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.

fix: phy: marvell: cp110: rename comphy_index to cp_index

2017-05-09T11:38:18+00:00

No functional change.
The variable name "comphy_index" is misleading, it represents
cp index and not comphy index.

phy: marvell: print comphy status even when it's disconnected

2017-05-09T11:38:18+00:00

since now the COMPHY can also be ignored, we must know the
state of the COMPHY. we cannot assume anymore that a missing
COMPHY is unconnected.

phy: marvell: add IGNORE COMPHY type

2017-05-09T11:38:18+00:00

This type tells u-boot to preserve the COMPHY settings as is
it is usefull in situations where the COMPHY was initialized by
earlier firmware.
Note that IGNORE is different from UNCONNECTED since setting
UNCONNECTED type will disconnect the COMPHY in the COMPHY MUX
which is a desired behaviour

The serdes was always configured in root complex mode.
this patch add new entry in device tree (per serdes)
which indicates whether the serdes is in end point mode.
if so, it skips the root complex configuration.

fix: mvebu_ comphy: Update COMPHY sequence number

2017-05-09T11:38:18+00:00

Use local static counter for maintaining the COMPHY chip-ID
upon its initialization.
The dev->seq originally used as the COMPHY chip-ID depends
on the device tree scan order and produces wrong results
that breaks the deficated PHYs init flow, which in turn
breaks the USB support.

dm: core: Replace of_offset with accessor

2017-02-08T13:12:14+00:00

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.
