Just want to update the thread to let you know: We are working on this. :) The information that can be updated here is as follows: 1. Qualcomm has a reference spec design for EC (Embedded Controller), and OEMs are able to customize it according to their design. The reference spec design may regardless of ITE or other EC vendors. 2. the reference EC spec will be supported on Qualcomm Compute reference designs for other platform as well. This is irrespective of the underlying transport (I2C, I3C, or any other Qualcomm proprietary transport. Some of the main functionalities in this patch series appear to align with the spec reference design. Therefore, it could be possibly extended to become a more generic EC driver that supports a wider range of devices. > > I want to personally thank you for your current support and efforts.
