phy: drop probe registration printks

2025-06-16T17:24:21+00:00

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

	snps-eusb2-hsphy 88e1000.phy: Registered Snps-eUSB2 phy
	qcom-eusb2-repeater c432000.spmi:pmic@7:phy@fd00: Registered Qcom-eUSB2 repeater
	qcom-eusb2-repeater c432000.spmi:pmic@a:phy@fd00: Registered Qcom-eUSB2 repeater
	qcom-eusb2-repeater c432000.spmi:pmic@b:phy@fd00: Registered Qcom-eUSB2 repeater
	snps-eusb2-hsphy fd3000.phy: Registered Snps-eUSB2 phy
	snps-eusb2-hsphy fd9000.phy: Registered Snps-eUSB2 phy
	snps-eusb2-hsphy fde000.phy: Registered Snps-eUSB2 phy
	snps-eusb2-hsphy 88e0000.phy: Registered Snps-eUSB2 phy
	snps-eusb2-hsphy 88e2000.phy: Registered Snps-eUSB2 phy

Drop (or demote to debug level) unnecessary registration info messages
to make boot logs a little less noisy.

phy: marvell: Do not enable by default during compile testing

2025-04-11T07:18:34+00:00

Enabling the compile test should not cause automatic enabling of all

phy: mvebu-cp110-utmi: support swapping d+/d- lanes by dts property

2024-10-07T06:30:19+00:00

CP11x UTMI PHY supports swapping D+/D- signals via digital control
register 1.

Add support for the "swap-dx-lanes" device-tree property, which lists
the port-ids that should swap D+ and D-.
The property is evaluated in probe and applied before power-on
during mvebu_cp110_utmi_port_setup.

phy: marvell: phy-mvebu-cp110-comphy: improve eth_port1 on comphy4

2024-08-04T17:22:11+00:00

According to the CN9100_MPP_information document, CP_SRD4 (comphy 4)
supports 2500 BASE-X and 5000 BASE-R for ETH_PORT1. I was able to test
that 2500 BASE-X is indeed supported. Unfortunately, our HW does not
support 5000 BASE-R, but I assume from the document that it does, so I
set the muxing there too to 0x1.

phy: marvell: a3700-comphy: Fix out of bounds read

2024-04-05T17:02:00+00:00

There is an out of bounds read access of 'gbe_phy_init_fix[fix_idx].addr'
every iteration after 'fix_idx' reaches 'ARRAY_SIZE(gbe_phy_init_fix)'.

Make sure 'gbe_phy_init[addr]' is used when all elements of
'gbe_phy_init_fix' array are handled.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

phy: constify of_phandle_args in xlate

2024-02-23T12:13:14+00:00

The xlate callbacks are supposed to translate of_phandle_args to proper
provider without modifying the of_phandle_args.  Make the argument
pointer to const for code safety and readability.

phy: armada-38x: add mux value for gbe port 0 on serdes 0

2024-01-24T05:53:12+00:00

Armada 38x supports 3 functions on serdes #0:
- pcie port 0
- sata port 0
- gbe port 0

Add missing entry for gbe port 0 on serdes 0 to the gbe_mux array.

Because this array looks obscure to new readers, also add a comment
explaining the meaning of rows, columns and values.

phy: Use device_get_match_data()

2023-10-13T10:15:40+00:00

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.
