treewide: Clean up DECLARE_GLOBAL_DATA_PTR usage

2026-02-17T19:50:22+00:00

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

net: phy: fixed: Be compatible with live OF tree

2021-04-15T08:52:17+00:00

On systems that use CONFIG_OF_LIVE, the "ofnode" type is defined
as const struct device_node *np, while on the flat DT systems it
is defined as a long of_offset into gd->fdt_blob.

It is desirable that the fixed PHY driver uses the higher-level
ofnode abstraction instead of parsing gd->fdt_blob directly,
because that enables it to work on live OF systems.

The fixed PHY driver has used a nasty hack since its introduction in
commit db40c1aa1c10 ("drivers/net/phy: add fixed-phy /
fixed-link support"),
which is to pass the long gd->fdt_blob offset inside int phydev->addr
(a value that normally holds the MDIO bus address at which the PHY
responds). Even ignoring the fact that the types were already
mismatched leading to a potential truncation (flat OF offset was
supposed to be a long and not an int), we really cannot extend this
hack any longer, because there's no way an int will hold the other
representation of ofnode, the struct device_node *np.

So we unfortunately need to do the right thing, which is to use the
framework introduced by Grygorii Strashko in
commit eef0b8a930d1 ("net: phy: add ofnode node to struct phy_device").
This will populate phydev->node for the fixed PHY.

Note that phydev->node will not be valid in the probe function, since
that is called synchronously from phy_device_create and we really have
no way of passing the ofnode directly through the phy_device_create API.
So we do what other drivers do too: we move the OF parsing logic from
the .probe to the .config method of the PHY driver. The new function
will be called at phy_config() time.

I do believe I've converted all the possible call paths for creating
a PHY with PHY_FIXED_ID, so there is really no reason to maintain
compatibility with the old logic of retrieving a flat OF tree offset
from phydev->addr. We just pass 0 to phydev->addr now.

net: phy: fixed: support speeds of 2500 and 10000

2021-02-16T16:48:20+00:00

Unlike the Linux fixed PHY driver, the one in U-Boot does not attempt to
emulate the clause 22 register set of a gigabit copper PHY driver
through the swphy framework. Therefore, the limitation of being unable
to support speeds higher than gigabit in fixed-link does not apply to
the U-Boot fixed PHY driver. This makes the fixed-link U-Boot
implementation more similar to the one from phylink, which can work with
any valid link speed.
