phy: marvell: Support changing SERDES map in board file

2018-09-19T06:59:26+00:00

This adds a weak definition of comphy_update_map to comphy_core,
which does nothing. If this function is defined elsewhere, for example
in board file, the board file can change some parameters of SERDES
configuration.

This is needed on Turris Mox, where the SERDES speed on lane 1 has to
be set differently when SFP module is connected and when Topaz Switch
module is connected.

This is a temporary solution. When the comphy driver for armada-3720
will be added to the kernel, the comphy driver in u-boot shall also be
updated and this should be done differently then.

phy: marvell: mux: Support nontrivial node order in selector register

2018-05-14T08:00:15+00:00

Currently comphy_mux supports only trivial order of nodes in pin
selector register, that is lane N on position N*bitcount.

Add support for nontrivial order, with map stored in device tree
property mux-lane-order.

This is needed for Armada 37xx.

As far as I know, there is no driver for Armada 37xx comphy in the
kernel. When such a driver comes, this will need to be rewritten to
support the device tree bindings from the kernel.

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.
