The changes also add ACPI support for all existing DAA\nmethods like SETDASA, SETNEWDA as well as I2C devices on I3C bus.\n\nSPD5118 and similar devices on DDR5 memory modules differ from typical\nI3C devices in their initialization. They use SETAASA broadcast CCC\ninstead of ENTDAA for address assignment, and per JEDEC specification,\nare not required to have a Provisioned ID or implement standard device\ninformation CCC commands (GETPID, GETDCR, GETBCR).\n\nThe series enables to describe all I3C and I2C devices on both Device\nTree and the ACPI table, using unified device property APIs throughout\nthe I3C core and the Synopsys DesignWare I3C master driver.\n\nPlease note that the series modifies drivers across multiple subsystems,\nlike Device Tree bindings, ACPI, I3C and HWMON.\n\nv2->v3:\n * Fix maximum value and indent bit list for mipi-i3c-static-method.\n * Move I3C_ADDR_METHOD_* macros to dt-bindings header.\n * Drop ACPICA commit IDs, keep only the Link: tags.\n * Revert the change which proceeds to register other devices if SETAASA\n is not supported so that it aligns with the rest of the driver and to\n avoid the issues pointed by Sashiko.\n * Rework multiple commit messages.\n\nv1->v2:\n * Added patch to remove 16-bit addressing support for SPD5118\n * Guard ACPI calls with #ifdef CONFIG_ACPI\n * Remove CONFIG_OF guard for of_alias_get_highest_id()\n * Mask mipi-i3c-static-method in the driver to select only valid values.\n * Proceed to register other devices if SETAASA is not supported.\n * Update commit message and links in the description of multiple commits.\n\n\nAkhil R (13):\n dt-bindings: i3c: Add mipi-i3c-static-method to support SETAASA\n ACPICA: Read LVR from the I2C resource descriptor\n i3c: master: Use unified device property interface\n i3c: master: Support ACPI enumeration of child devices\n i3c: master: Add support for devices using SETAASA\n i3c: master: Add support for devices without PID\n i3c: master: match I3C device through DT and ACPI\n i3c: dw-i3c-master: Add SETAASA as supported CCC\n i3c: dw-i3c-master: Add a quirk to skip clock and reset\n i3c: dw-i3c-master: Add ACPI ID for Tegra410\n hwmon: spd5118: Remove 16-bit addressing\n hwmon: spd5118: Add I3C support\n arm64: defconfig: Enable I3C and SPD5118 hwmon\n\n .../devicetree/bindings/i3c/i3c.yaml | 31 +-\n arch/arm64/configs/defconfig | 3 +\n drivers/acpi/acpica/rsserial.c | 6 +-\n drivers/hwmon/Kconfig | 9 +-\n drivers/hwmon/spd5118.c | 119 +++---\n drivers/i3c/master.c | 354 +++++++++++++++---\n drivers/i3c/master/dw-i3c-master.c | 66 ++--\n include/acpi/acrestyp.h | 1 +\n include/dt-bindings/i3c/i3c.h | 3 +\n include/linux/i3c/ccc.h | 1 +\n include/linux/i3c/master.h | 20 +-\n 11 files changed, 463 insertions(+), 150 deletions(-)" }
