Update existing approach of using compatible to differentiate between devices that support QSGMII mode and those that don't. The new approach involves storing the number of qsgmii main ports for the device in the num_qsgmii_main_ports member of the "struct phy_gmii_sel_soc_data". This approach makes it scalable for newer devices. ========= Changelog ========= v1 -> v2: 1. Drop all patches corresponding to SGMII mode. This is done since I do not have a method to test SGMII in the standard mode which uses an SGMII PHY. The previous series used SGMII in a fixed-link mode, bypassing the SGMII PHY. I will post the SGMII patches in a future series after testing them. 2. Update description for the property "ti,qsgmii-main-ports", to describe it in a unified way across the compatibles. 3. Add minItems, maxItems, and items at the top, where the property "ti,qsgmii-main-ports" is first defined. Modify them later appropriately, based on the compatible. 4. Update the method to fetch the property "ti,qsgmii-main-ports" from the device-tree, to make it scalable. 5. Use dev_err() when the value(s) provided in the device-tree for the property "ti,qsgmii-main-ports" is/are invalid. v1: https://lore.kernel.org/r/20220914093911.187764-1-s-vadapalli@ti.com/ Siddharth Vadapalli (3): dt-bindings: phy: ti: phy-gmii-sel: Add bindings for J721e phy: ti: gmii-sel: Update methods for fetching and using qsgmii main port phy: ti: gmii-sel: Add support for CPSW9G GMII SEL in J721e .../bindings/phy/ti,phy-gmii-sel.yaml | 48 +++++++++++++++---- drivers/phy/ti/phy-gmii-sel.c | 42 +++++++++++++--- 2 files changed, 75 insertions(+), 15 deletions(-)
