Signed-off-by: Ryan Chen --- Changes in v4: - Indent the register bitfield definitions so they are distinguishable from the register offsets, and use lowercase hex. - Set PHY3S00_SRAM_EXT_LOAD rather than PHY3S00_SRAM_BYPASS. Bypassing the SRAM leaves the PHY on the default RTL design configuration, whereas the external load path applies the ROM patch so the PHY runs the ROM configuration. - Describe the SRAM handshake in the driver's commit message. - Link to v3: https://lore.kernel.org/r/20260701-upstream_usb3phy-v3-0-00e12315b6f9@aspeedtech.com Changes in v3: - Wire drivers/phy/aspeed/ into drivers/phy/Kconfig and drivers/phy/Makefile so the driver is actually built. - Fix the Makefile config symbol to CONFIG_PHY_ASPEED_USB3 to match the Kconfig symbol. - Expand the Kconfig help text. - Link to v2: https://lore.kernel.org/r/20260116-upstream_usb3phy-v2-0-0b0c9f3eb6f4@aspeedtech.com Changes in v2: - aspeed,ast2700-usb3-phy.yaml - Drop clocks, resets descripton. - Kconfig - add COMPILE_TEST, remove default n - Link to v1: https://lore.kernel.org/r/20260114-upstream_usb3phy-v1-0-2e59590be2d7@aspeedtech.com --- Ryan Chen (3): dt-bindings: phy: aspeed: Document AST2700 USB3.2 PHY phy: aspeed: Add AST2700 USB3.2 PHY driver MAINTAINERS: Add ASPEED USB3 PHY driver .../bindings/phy/aspeed,ast2700-usb3-phy.yaml | 48 +++++ MAINTAINERS | 8 + drivers/phy/Kconfig | 1 + drivers/phy/Makefile | 1 + drivers/phy/aspeed/Kconfig | 15 ++ drivers/phy/aspeed/Makefile | 2 + drivers/phy/aspeed/phy-aspeed-usb3.c | 236 +++++++++++++++++++++ 7 files changed, 311 insertions(+) --- base-commit: f82a5da2f04960df9fb57489992d03dd5e64ec6f change-id: 20260112-upstream_usb3phy-7116f8dfe779 Best regards, -- Ryan Chen
