The PHY_POL_NORMAL, PHY_POL_INVERT, and\nPHY_POL_AUTO constants are consumed from dts/upstream/include, which is\nalready on the compiler include path.\n\nPatch 2 updates the Airoha EN8811H PHY driver to use the new standard\nrx-polarity and tx-polarity properties, with backward compatibility\nfallback to the now-deprecated airoha,pnswap-rx and airoha,pnswap-tx\nboolean properties.\n\nPatch 3 adds sandbox DM unit tests for the new library, ported from\nthe Linux KUnit test (linux/drivers/phy/phy-common-props-test.c), along\nwith the 8 sandbox DT test nodes in arch/sandbox/dts/test.dts and the\nCONFIG_PHY_COMMON_PROPS=y entry in configs/sandbox_defconfig. 16 unit\ntest cases (8 for rx, 8 for tx) cover: missing property, single value\nwith no names array, count mismatches, name-based lookup, missing\ndefault fallback, default fallback, and unsupported polarity value.\n\nChanges in v4:\n- Squash former patches 3 and 4 into a single patch to fix bisectability\n (the test code referenced DT nodes that were only added in the\n following patch)\n- Add CONFIG_PHY_COMMON_PROPS=y to configs/sandbox_defconfig\n- patch 1: replace printf with pr_err for error-condition messages in\n phy-common-props.c\n- patch 2: use phy_string_for_interface() instead of direct array access\n phy_interface_strings[] in en8811h_config_serdes_polarity()\n- patch 2: remove unused local variables ofnode node and u32 pbus_value\n from en8811h_config()\n\nChanges in v3:\n- patch 1: fix ofnode_get_u32_prop_for_name() to apply default_val and\n return 0 when the polarity property is absent, instead of returning\n -ENOENT; update @node and @default_val kdoc accordingly — this aligns\n the \"missing property\" path with the behaviour expected by\n phy_get_manual_rx/tx_polarity() and is validated by the new unit tests\n- Add unit tests for the PHY_COMMON_PROPS library (patches 3-4), ported\n from Linux KUnit test linux/drivers/phy/phy-common-props-test.c\n- Add test/dm/Makefile build entry gated on CONFIG_PHY_COMMON_PROPS\n- Add 8 sandbox DT nodes to arch/sandbox/dts/test.dts covering all test\n scenarios; include in test.dts\n\nChanges in v2:\n- Drop DT binding patches (v1 patches 1 and 3): already merged via\n the DTS upstream subtree merge (tag 'v7.0-rc2-dts')\n- Drop creation of include/dt-bindings/phy/phy.h: the header is now\n provided by dts/upstream/include/dt-bindings/phy/phy.h, which is\n already in the build's include search path\n\nLucien.Jheng (3):\n phy: add common PHY properties support\n net: phy: airoha: air_en8811: use standard rx-polarity/tx-polarity properties\n test: dm: add PHY common props unit tests and sandbox DT nodes\n\n arch/sandbox/dts/test.dts | 60 +++++\n configs/sandbox_defconfig | 1 +\n drivers/net/phy/airoha/Kconfig | 1 +\n drivers/net/phy/airoha/air_en8811.c | 60 +++--\n drivers/phy/Kconfig | 8 +\n drivers/phy/Makefile | 1 +\n drivers/phy/phy-common-props.c | 286 ++++++++++++++++++++++++\n include/linux/phy/phy-common-props.h | 69 ++++++\n test/dm/Makefile | 1 +\n test/dm/phy_common_props.c | 319 +++++++++++++++++++++++++++\n 10 files changed, 790 insertions(+), 16 deletions(-)\n create mode 100644 drivers/phy/phy-common-props.c\n create mode 100644 include/linux/phy/phy-common-props.h\n create mode 100644 test/dm/phy_common_props.c\n\n--\n2.34.1"}
