Add support for SPD5118 (Jedec JESD300) compliant chips supporting a temperature sensor and SPD NVRAM. Such devices are typically found on DDR5 memory modules. The first patch of the series adds SPD5118 devicetree bindings. The second patch adds support for SPD5118 temperature sensors. The third patch adds support for suspend/resume. The 4th patch adds support for reading the SPD NVRAM. The 5th patch adds support for auto-detecting SPD5118 compliant chips to i2c_register_spd() in the i2c-smbus code. The last patch of the series adds a configuration option to make the auto-detect code in the spd5118 driver configurable. Note: The driver introduced with this patch series does not currently support accessing SPD5118 compliant chips in I3C mode. v5: Added Tested-by: tags Cosmetic changes Added reference to LPDDR5 to subject and description of patch 5/6 Updated comments associated with i2c_register_spd() to include support for (LP)DDR5 Replaced #ifdef with IS_ENABLED() and included address_list in conditional code of patch 6/6 v4: Add support for detecting SPD5118 compliant chips in i2c-smbus driver Make auto-detect code in driver optional Fix suspend code Ignore failure to register with nvmem core if it is disabled Use NVMEM_DEVID_NONE instead of NVMEM_DEVID_AUTO in nvmem code, changing nvmem attribute directories from 0-005[0-7]X to 0-005[0-7] v3: Drop explicit bindings document; add binding to trivial devices instead Add support for reading SPD NVRAM v2: Drop PEC support; it only applies to I3C mode.
