This series converts the DPAA driver to phylink. Additionally, it also adds a serdes driver to allow for dynamic reconfiguration between 1g and 10g interfaces (such as in an SFP+ slot). These changes are submitted together for this RFT, but they will eventually be submitted separately to the appropriate subsystem maintainers. I have tried to maintain backwards compatibility with existing device trees whereever possible. However, one area where I was unable to achieve this was with QSGMII. Please refer to patch 4 for details. All mac drivers have now been converted. I would greatly appreciate if anyone has QorIQ boards they can test/debug this series on. I only have an LS1046ARDB. Everything but QSGMII should work without breakage; QSGMII needs patches 42 and 43. The serdes driver is mostly functional (except for XFI). This series only adds support for the LS1046ARDB SerDes (and untested LS1088ARDB), but it should be fairly straightforward to add support for other SoCs and boards (see Documentation/driver-api/phy/qoriq.rst). This is the last spin of this series with all patches included. After next week (depending on feedback) I will resend the patches broken up as follows: - 5: 1000BASE-KX support - 1, 6, 44, 45: Lynx 10G support - 7-10, 12-14: Phy rate adaptation support - 2-4, 15-43, 46, 47: DPAA phylink conversion Patches 15-19 were first submitted as [1]. [1] https://lore.kernel.org/netdev/20220531195851.1592220-1-sean.anderson@xxxxxxxx/ Changes in v3: - Manually expand yaml references - Add mode configuration to device tree - Expand pcs-handle to an array - Incorperate some minor changes into the first FMan binding commit - Add vendor prefix 'fsl,' to rgmii and mii properties. - Set maxItems for pcs-names - Remove phy-* properties from example because dt-schema complains and I can't be bothered to figure out how to make it work. - Add pcs-handle as a preferred version of pcsphy-handle - Deprecate pcsphy-handle - Remove mii/rmii properties - Add 1000BASE-KX interface mode - Rename remaining references to QorIQ SerDes to Lynx 10G - Fix PLL enable sequence by waiting for our reset request to be cleared before continuing. Do the same for the lock, even though it isn't as critical. Because we will delay for 1.5ms on average, use prepare instead of enable so we can sleep. - Document the status of each protocol - Fix offset of several bitfields in RECR0 - Take into account PLLRST_B, SDRST_B, and SDEN when considering whether a PLL is "enabled." - Only power off unused lanes. - Split mode lane mask into first/last lane (like group) - Read modes from device tree - Use caps to determine whether KX/KR are supported - Move modes to lynx_priv - Ensure that the protocol controller is not already in-use when we try to configure a new mode. This should only occur if the device tree is misconfigured (e.g. when QSGMII is selected on two lanes but there is only one QSGMII controller). - Split PLL drivers off into their own file - Add clock for "ext_dly" instead of writing the bit directly (and racing with any clock code). - Use kasprintf instead of open-coding the snprintf dance - Support 1000BASE-KX in lynx_lookup_proto. This still requires PCS support, so nothing is truly "enabled" yet. - Add support for phy rate adaptation - Support differing link speeds and interface speeds - Adjust advertisement based on rate adaptation - Adjust link settings based on rate adaptation - Add support for CRS-based rate adaptation - Add support for AQR115 - Add some additional phy interfaces - Add support for aquantia rate adaptation - Put the PCS mdiodev only after we are done with it (since the PCS does not perform a get itself). - Remove _return label from memac_initialization in favor of returning directly - Fix grabbing the default PCS not checking for -ENODATA from of_property_match_string - Set DTSEC_ECNTRL_R100M in dtsec_link_up instead of dtsec_mac_config - Remove rmii/mii properties - Replace 1000Base... with 1000BASE... to match IEEE capitalization - Add compatibles for QSGMII PCSs - Split arm and powerpcs dts updates - Describe modes in device tree - ls1088a: Add serdes bindings Changes in v2: - Rename to fsl,lynx-10g.yaml - Refer to the device in the documentation, rather than the binding - Move compatible first - Document phy cells in the description - Allow a value of 1 for phy-cells. This allows for compatibility with the similar (but according to Ioana Ciornei different enough) lynx-28g binding. - Remove minItems - Use list for clock-names - Fix example binding having too many cells in regs - Add #clock-cells. This will allow using assigned-clocks* to configure the PLLs. - Document the structure of the compatible strings - Convert FMan MAC bindings to yaml - Better document how we select which PCS to use in the default case - Rename driver to Lynx 10G (etc.) - Fix not clearing group->pll after disabling it - Support 1 and 2 phy-cells - Power off lanes during probe - Clear SGMIIaCR1_PCS_EN during probe - Rename LYNX_PROTO_UNKNOWN to LYNX_PROTO_NONE - Handle 1000BASE-KX in lynx_proto_mode_prep - Remove some unused variables - Fix prototype for dtsec_initialization - Fix warning if sizeof(void *) != sizeof(resource_size_t) - Specify type of mac_dev for exception_cb - Add helper for sanity checking cgr ops - Add CGR update function - Adjust queue depth on rate change - Move PCS_LYNX dependency to fman Kconfig - Remove unused variable slow_10g_if - Restrict valid link modes based on the phy interface. This is easier to set up, and mostly captures what I intended to do the first time. We now have a custom validate which restricts half-duplex for some SoCs for RGMII, but generally just uses the default phylink validate. - Configure the SerDes in enable/disable - Properly implement all ethtool ops and ioctls. These were mostly stubbed out just enough to compile last time. - Convert 10GEC and dTSEC as well - Fix capitalization of mEMAC in commit messages - Add nodes for QSGMII PCSs - Add nodes for QSGMII PCSs - Use one phy cell for SerDes1, since no lanes can be grouped - Disable SerDes by default to prevent breaking boards inadvertently.
