netsec: ignore 'phy-mode' device property on ACPI systems

2020-10-29T09:08:10+00:00

[ Upstream commit acd7aaf51b20263a7e62d2a26569988c63bdd3d8 ]

Since commit bbc4d71d63549bc ("net: phy: realtek: fix rtl8211e rx/tx
delay config"), the Realtek PHY driver will override any TX/RX delay
set by hardware straps if the phy-mode device property does not match.

This is causing problems on SynQuacer based platforms (the only SoC
that incorporates the netsec hardware), since many were built with
this Realtek PHY, and shipped with firmware that defines the phy-mode
as 'rgmii', even though the PHY is configured for TX and RX delay using
pull-ups.

From the driver's perspective, we should not make any assumptions in
the general case that the PHY hardware does not require any initial
configuration. However, the situation is slightly different for ACPI
boot, since it implies rich firmware with AML abstractions to handle
hardware details that are not exposed to the OS. So in the ACPI case,
it is reasonable to assume that the PHY comes up in the right mode,
regardless of whether the mode is set by straps, by boot time firmware
or by AML executed by the ACPI interpreter.

So let's ignore the 'phy-mode' device property when probing the netsec
driver in ACPI mode, and hardcode the mode to PHY_INTERFACE_MODE_NA,
which should work with any PHY provided that it is configured by the
time the driver attaches to it. While at it, document that omitting
the mode is permitted for DT probing as well, by setting the phy-mode
DT property to the empty string.

dt: fix broken links due to txt->yaml renames

2020-06-18T16:45:05+00:00

There are some new broken doc links due to yaml renames
at DT. Developers should really run:

	./scripts/documentation-file-ref-check

in order to solve those issues while submitting patches.
This tool can even fix most of the issues with:

	./scripts/documentation-file-ref-check --fix

dt-bindings: Fix more incorrect 'reg' property sizes in examples

2020-06-11T20:12:09+00:00

The examples template is a 'simple-bus' with a size of 1 cell for
had between 2 and 4 cells which really only errors on I2C or SPI type
devices with a single cell.

The easiest fix in most cases is to change the 'reg' property to 1 cell
for address and size.

dt-bindings: Remove more cases of 'allOf' containing a '$ref'

2020-06-11T19:50:43+00:00

Another round of 'allOf' removals that came in this cycle.

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.

This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.

dt-bindings: net: rename the bindings document for MediaTek STAR EMAC

2020-05-30T00:07:13+00:00

The driver itself was renamed before getting merged into mainline, but
the binding document kept the old name. This makes both names consistent.
