ARC: HSDK: split HSDK and HSDK-4xD DTS

2020-04-27T08:20:26+00:00

Split HSDK and HSDK-4xD device tree files so they can have
different model names.

As the driver of on-chip reset controller became available
we are ready to enable it.

NET: DW: fix regression for ARC boards

2019-10-07T17:23:49+00:00

The commit
642b80d256e ("net: designware: drop compatible altr, socfpga-stmmac")
breaks designware ethernet for all ARC boards. It removes
"altr, socfpga-stmmac" compatible from "drivers/net/designware.c"
without changing compatible in the boards which use it.

Fix that by adding "snps,arc-dwmac-3.70a" compatible string to
"drivers/net/designware.c" and using it in ARC boards device tree.

dts: switch spi-flash to jedec, spi-nor compatible

2019-04-12T05:24:27+00:00

There is no reason not to use the Linux "jedec,spi-nor" binding in U-Boot
dts files. This compatible has been added in sf_probe, let use it.

This patch switches to jedec,spi-nor when spi-flash is used in the DTS
and DTSI files, and removed spi-flash when jedec,spi-nor is already
present.

The x86 dts are switched in a separate commit since it depends on a change
in fdtdec.

ARC: Add model property to boards .dts

2018-10-05T13:55:42+00:00

1. This way we sync with Linux kernel where we have model
   set for all ARC boards for quite some time, see [1]

2. Once we enable DISPLAY_BOARDINFO for ARC this info will
   be printed on boot givin some extra data-point about the board

ARC: HSDK: Fix timer frequency value

2018-09-05T15:11:45+00:00

CPU (and hence cpu timers) on HSDK board runs at 500MHz after
preloader so fix wrong CPU frequency value in hsdk.dts

GPIO: CREG: improve flexibility of hsdk-creg-gpio driver

2018-07-31T04:49:47+00:00

CREG GPIO is a driver for weird soc-specific output ports, which are
controlled by some fields in memory mapped register.

Example:

31                 9        7        5           0   < bit number
|                  |        |        |           |
[     not used     | gpio-1 | gpio-0 | <-shift-> ]   < 32 bit register
                       ^        ^
                       |        |
                write 0x2 == set output to "1" (activate)
                write 0x3 == set output to "0" (deactivate)

As of tooday we only support fixed (hardcoded) bit per gpio line,
activate / deactivatei and shift values. Fix that by read them from
device tree to be able to use this driver for other boards.

Remove "hsdk" prefix from compatible string as this driver can be
used with different boards like HSDK, AXS101, AXS103, etc.

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.

ARC: HSDK: Enable SPI flash support

2018-04-02T09:27:56+00:00

HSDK board has sst26wf016 SPI flash IC which we want to support.

Add SPI controller, CS-gpio and SPI flash nodes to hsdk device tree.
Enable corresponding options in hsdk defconfig.

For SPI write functionality to work we need [1] which
adds support of sst26xxx ICs.
