Hi,
This is v2 of the series to introduce UCLASS_SOC to be used for SOC identification and attribute matching based on SoC ID info. The first version of this series can be found at [1].
Biggest change is the addition of a patch to add documentation for the SOC ID framework as requested by several folks. Otherwise, several comments were addressed in the patch to introduce the UCLASS_SOC implementation:
* Renamed soc_device_attribute to soc_attr. * Added inline docs for same struct. * Moved ifdef for CONFIG_SOC_DEVICE to only include functions * Documented NULL return possiblity for soc_device_match.
And a change to SOC Revision macro naming in the soc_ti_k3 driver to use SR consistently instead of PG.
Regards, Dave
