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 last patch adds support for reading the SPD NVRAM. Note: The driver introduced with this patch series does not currently support accessing SPD5118 compliant chips in I3C mode. 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.
