Since the binding still\nrepresents the same (AST2600 SoC) physical hardware, we continue to use\nthe existing compatible string of \"aspeed,ast2600-i2c-bus\".\n\nHowever: since we're changing semantics for an existing binding, we\nallow backwards compatibility by selecting on presence/absence of the\nnewly-added properties, and fall back to the old driver (ie., in\ncompatibility mode) when we detect a DT using the old binding spec.\n\nSpecifically:\n\n- ast2600-i2c-bus nodes that provide the `aspeed,global-regs` property\n (which is mandatory in the new binding and absent in the legacy\n binding) will be successfully probed by the new driver\n\n- ast2600-i2c-bus nodes without `aspeed,global-regs` continue to use the\n existing driver (in legacy register mode), ensuring that platforms\n with the current DTBs remain functional\n\nSigned-off-by: Ryan Chen <ryan_chen@aspeedtech.com>\n---\nChanges in v28:\n- 2/4: update commit message correspond with aspeed,enable-dma.\n- 2/4: remove aspeed,transfer-mode and add aspeed,enable-dma property\n and description.\n- 2/4: Fix aspeed,enable-dma description to reflect hardware capability\n rather than software behavior.\n- 3/4: Separate xfer_mode_store into distinct parse and availability-check\n steps by introducing ast2600_i2c_xfer_mode_check().\n- 3/4: fix tx dma memcpy source point address.\n- 3/4: Use a temporary variable for devm_platform_get_and_ioremap_resource()\n to avoid storing an ERR_PTR in i2c_bus->buf_base; drop the redundant\n NULL assignment in the error path since i2c_bus is kzalloc()ed.\n- 3/4: Add ABI documentation file\n Documentation/ABI/testing/sysfs-driver-ast2600-i2c.\n- 4/4: fix typo condication -> condition.\n- 4/4: fix compile error, when disable CONFIG_I2C_SLAVE.\n- Link to v27: https://lore.kernel.org/r/20260324-upstream_i2c-v27-0-f19b511c8c28@aspeedtech.com\n\nChanges in v27:\n- 1/4 use aspeed,enable-dma instead aspeed,transfer-mode.\n- 2/4 remove aspeed,transfer-mode selection instad aspeed,transfer-mode\n- 2/4 add sysfs for xfer mode.\n- Link to v26: https://lore.kernel.org/r/20260309-upstream_i2c-v26-0-5fedcff8ffe8@aspeedtech.com\n\nChanges in v26:\n- 1/4: binding reworks based on review feedback\n- Link to v25: https://lore.kernel.org/r/20260225-upstream_i2c-v25-0-9f4bdd954f3f@aspeedtech.com\n\nChanges in v25:\n- Use b4 to send series.\n- Rebase on v7.0-rc1.\n- Clarify cover letter and commit logs based on review feedback.\n- Remove the i2c-aspeed-core multiplexer infrastructure and\n implement driver selection via conditional -ENODEV handling\n in individual probe() functions.\n- 3/4: incorporate review feedback and refactor new driver\n- Link to v24: https://lore.kernel.org/r/20251118014034.820988-1-ryan_chen@aspeedtech.com\n\nChanges in v24:\n- aspeed,ast2600-i2c.yaml\n -
