2024-02-23phy: constify of_phandle_args in xlateKrzysztof Kozlowski
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.

The resume callback restores the submode of each PHY. It uses the submode stored in struct phy_gmii_sel_phy_priv (variable phy_if_mode). The submode was saved by the set_mode PHY operation.

When the node for this phy selector is a child node of a syscon node then the property 'reg' is used as an offset into the parent regmap. When the node is standalone and gets its own regmap this offset is pre-applied. So we need to track which method was used to get the regmap and not apply the offset in the standalone case.

In TI's J7200, each of the CPSW5G ethernet interfaces can act as a QSGMII or QSGMII-SUB port. The QSGMII interface is responsible for performing auto-negotiation between the MAC and the PHY while the rest of the interfaces are designated as QSGMII-SUB interfaces, indicating that they will not be taking part in the auto-negotiation process. To indicate the interface which will serve as the main QSGMII interface, add a property "ti,qsgmii-main-ports", whose value indicates the port number of the interface which shall serve as the main QSGMII interface. The rest of the interfaces are then assigned QSGMII-SUB mode by default. The property "ti,qsgmii-main-ports" is used to configure the CTRLMMR_ENETx_CTRL register. Depending on the device, it is possible for more than one QSGMII main port to exist. Thus, the property "ti,qsgmii-main-ports" is defined as an array of values in order to reuse the property for other devices.

2018-12-12phy: ti: introduce phy-gmii-sel driverGrygorii Strashko
TI am335x/am437x/dra7(am5)/dm814x CPSW3G Ethernet Subsystem supports two 10/100/1000 Ethernet ports with selectable G/MII, RMII, and RGMII interfaces. The interface mode is selected by configuring the MII mode selection register(s) (GMII_SEL) in the System Control Module chapter (SCM). GMII_SEL register(s) and bit fields placement in SCM are different between SoCs while fields meaning is the same. Historically CPSW external Port's interface mode selection configuration was introduced using custom API and driver cpsw-phy-sel.c. This leads to unnecessary driver, DT binding and custom API support effort. This patch introduces CPSW Port's PHY Interface Mode selection Driver (phy-gmii-sel) which implements standard Linux PHY interface and used as a replacement for TI's specific driver cpsw-phy-sel.c and corresponding custom API.
