phy: mvebu-cp110-utmi: fix dr_mode property read from dts

2026-03-04T12:21:25+00:00

[ Upstream commit e2ce913452ab56b3330539cc443b97b7ea8c3a1a ] The problem with the current implementation is that it does not consider that the USB controller can have multiple PHY handles with different arguments count, as for example we have in our cn9131 based platform: "phys = <&cp0_comphy1 0>, <&cp0_utmi0>;". In such case calling "of_usb_get_dr_mode_by_phy" with -1 (no phy-cells) leads to not proper phy detection, taking the "marvell,cp110-utmi-phy" dts definition we can call the "of_usb_get_dr_mode_by_phy" with 0 (#phy-cells = <0>) and safely look for that phy.

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.

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.

phy: Explicitly include correct DT includes

2023-07-17T06:22:56+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
