phy: constify of_phandle_args in xlate

2024-02-23T12:13:14Z

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: mediatek: tphy: add support force phy mode switch

2023-12-21T17:09:59Z

this is used to be compatible with old SoCs, such as mt8195, which shares t-phy between usb3 and pcie controller, usually, it's default mode is pcie rc mode, and could use force mode to switch into usb3 mode, because pericfg layer doesn't provide mode switch, also no efuse or jumper can be used; Currently, only support switch from default pcie mode to usb3; Note: don't use this way on new SoCs, use pericfg layer's mode switch instead (by perperty "mediatek,syscon-type").

phy: Explicitly include correct DT includes

2023-07-17T06:22:56Z

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.

phy: mediatek: tphy: add debugfs files

2023-05-19T17:53:52Z

These debugfs files are mainly used to make eye diagram test easier, especially helpful to do HQA test for a new IC without efuse enabled. Signed-off-by: Chunfeng Yun Link: https://lore.kernel.org/r/20230513092218.21139-2-chunfeng.yun@mediatek.com Signed-off-by: Vinod Koul
