phy: ti: j721e-wiz: Fix device node reference leak in wiz_get_lane_phy_types()

2026-04-02T11:09:52+00:00

[ Upstream commit 584b457f4166293bdfa50f930228e9fb91a38392 ]

The serdes device_node is obtained using of_get_child_by_name(),
which increments the reference count. However, it is never put,
leading to a reference leak.

Add the missing of_node_put() calls to ensure the reference count is
properly balanced.

[ Upstream commit 53f6240e88c9e8715e09fc19942f13450db4cb33 ]

While suspend and resume mux selection was getting lost. So save and
restore these values in suspend and resume operations.

phy: ti: gmii-sel: fix regmap leak on probe failure

2026-01-23T10:18:44+00:00

commit 4914d67da947031d6f645c81c74f7879e0844d5d upstream.

The mmio regmap that may be allocated during probe is never freed.

Switch to using the device managed allocator so that the regmap is
released on probe failures (e.g. probe deferral) and on driver unbind.

phy: ti: da8xx-usb: Handle devm_pm_runtime_enable() errors

2026-01-23T10:18:41+00:00

[ Upstream commit 08aa19de72110df8ac10c9e67349dd884eeed41d ]

devm_pm_runtime_enable() can fail due to memory allocation. The current
code ignores its return value after calling pm_runtime_set_active(),
leaving the device in an inconsistent state if runtime PM initialization
fails.

Check the return value of devm_pm_runtime_enable() and return on
failure. Also move the declaration of 'ret' to the function scope
to support this check.

phy: drop probe registration printks

2026-01-23T10:18:41+00:00

[ Upstream commit 95463cbb4fe6489921fb8c72890113dca54ce83f ]

Drivers should generally be quiet on successful probe, but this is not
followed by some PHY drivers, for example:

phy: ti: gmii-sel: Do not use syscon helper to build regmap

2025-03-22T19:54:20+00:00

[ Upstream commit 5ab90f40121a9f6a9b368274cd92d0f435dc7cfa ]

The syscon helper device_node_to_regmap() is used to fetch a regmap
registered to a device node. It also currently creates this regmap
if the node did not already have a regmap associated with it. This
should only be used on "syscon" nodes. This driver is not such a
device and instead uses device_node_to_regmap() on its own node as
a hacky way to create a regmap for itself.

This will not work going forward and so we should create our regmap
the normal way by defining our regmap_config, fetching our memory
resource, then using the normal regmap_init_mmio() function.

phy: ti: phy-j721e-wiz: fix usxgmii configuration

2024-10-17T14:53:02+00:00

Commit b64a85fb8f53 ("phy: ti: phy-j721e-wiz.c: Add usxgmii support in
wiz driver") added support for USXGMII mode. In doing so, P0_REFCLK_SEL
was set to "pcs_mac_clk_divx1_ln_0" (0x3) and P0_STANDARD_MODE was set to
LANE_MODE_GEN1, which results in a data rate of 5.15625 Gbps. However,
since the USXGMII mode can support up to 10.3125 Gbps data rate, the
aforementioned fields should be set to "pcs_mac_clk_divx0_ln_0" (0x2) and
LANE_MODE_GEN2 respectively. The signal corresponding to the USXGMII lane
of the SERDES has been measured as 5 Gbps without the change and 10 Gbps
with the change. Hence, fix the configuration accordingly to support
USXGMII up to 10G.
