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: xsphy: remove macros used to prepare bitfield value

2022-09-24T06:27:49Z

Prefer to make use of FIELD_PREP() macro to prepare bitfield value, then no need local ones anymore. Signed-off-by: Chunfeng Yun Link: https://lore.kernel.org/r/20220920090038.15133-4-chunfeng.yun@mediatek.com Signed-off-by: Vinod Koul

phy: core: rework phy_set_mode to accept phy mode and submode

2018-12-12T04:31:33Z

Currently the attempt to add support for Ethernet interface mode PHY (MII/GMII/RGMII) will lead to the necessity of extending enum phy_mode and duplicate there values from phy_interface_t enum (or introduce more PHY callbacks) [1]. Both approaches are ineffective and would lead to fast bloating of enum phy_mode or struct phy_ops in the process of adding more PHYs for different subsystems which will make them unmaintainable. As discussed in [1] the solution could be to introduce dual level PHYs mode configuration - PHY mode and PHY submode. The PHY mode will define generic PHY type (subsystem - PCIE/ETHERNET/USB_) while the PHY submode - subsystem specific interface mode. The last is usually already defined in corresponding subsystem headers (phy_interface_t for Ethernet, enum usb_device_speed for USB). This patch is cumulative change which refactors PHY framework code to support dual level PHYs mode configuration - PHY mode and PHY submode. It extends .set_mode() callback to support additional parameter "int submode" and converts all corresponding PHY drivers to support new .set_mode() callback declaration. The new extended PHY API int phy_set_mode_ext(struct phy *phy, enum phy_mode mode, int submode) is introduced to support dual level PHYs mode configuration and existing phy_set_mode() API is converted to macros, so PHY framework consumers do not need to be changed (~21 matches).
