[7.0] [Feature] : Enable i3c ACPI enumeration and SPD5118 DDR5 temperature monitoring · Pull Request !13073 · anolis/cloud-kernel

bugzilla: https://bugzilla.openanolis.cn/show_bug.cgi?id=44797

Backport PS-24 and PS-25 from the Vera NV patch merge plan to enable DDR5
DIMM temperature monitoring through the DesignWare I3C master on Vera
(Tegra410) platforms. PS-25 adds ACPICA support for parsing the LVR field
of I2C serial bus resources, which PS-24's i3c ACPI enumeration consumes.
PS-24 enables ACPI enumeration of i3c child devices, SETAASA address
assignment, PID-less device support, the dw-i3c-master ACPI ID for
Tegra410 with a core clock frequency quirk, and SPD5118 hwmon I3C support.
Two NVIDIA downstream fixes for SETAASA devices (firmware modalias and
early device-add failure propagation) are ported from the NV branch since
they are not merged upstream. CONFIG_I3C, CONFIG_DW_I3C_MASTER and
CONFIG_SENSORS_SPD5118 are enabled as modules for arm64.

Of the 21 commits, 18 are upstream picks: 15 apply verbatim (patch content
identical to upstream), 3 required small conflict resolutions documented
in the Adaptation column below. The remaining commits are the 2 NV
downstream fixes and 1 anolis config enablement.

| Patchset | Patch Subject | Upstream Link | Status | Apply | Adaptation |
|----------|---------------|---------------|--------|-------|-------------|
| [ACPICA LVR] | ACPICA: Add LVR to acrestyp.h | [f0ee0b0927f7](https://git.kernel.org/linus/f0ee0b0927f7) | Picked | Clean | None |
|  | ACPICA: Change LVR to 8 bit value | [d364d76f3d0c](https://git.kernel.org/linus/d364d76f3d0c) | Picked | Adapted | [ conflict resolved: picked before 468adc6b1ff8 (upstream order is 468 then d364), so this pick adds the ACPI_RSC_MOVE8 lvr entry directly instead of converting the 1BITFLAG entry; cumulative result identical to upstream ] |
|  | ACPICA: Fetch LVR I2C resource descriptor | [468adc6b1ff8](https://git.kernel.org/linus/468adc6b1ff8) | Picked | Adapted | [ conflict resolved: lvr entry already added by the previous pick, this pick only bumps the conversion table size 17 to 18; cumulative result identical to upstream ] |

# Test

Built arm64 vmlinux and modules with CONFIG_I3C=m, CONFIG_DW_I3C_MASTER=m,
CONFIG_SENSORS_SPD5118=m: dw-i3c-master.ko, i3c.ko and spd5118.ko all link
cleanly with correct module dependencies (spd5118 depends on i3c,
regmap-i3c, regmap-i2c). Verified drivers/i3c/master.c,
drivers/i3c/master/dw-i3c-master.c and drivers/hwmon/spd5118.c are
byte-identical to the NVIDIA 26.04_linux-nvidia-bos branch after the
series (modulo baseline sysfs_emit differences in ANCK).
