[PATCH 16/16] nvmem: sfp: Add support for TA 2.1 devices

From: Srinivas Kandagatla
Date: Fri Apr 29 2022 - 12:29:01 EST


From: Sean Anderson <sean.anderson@xxxxxxxx>

This adds support for Trust Architecture (TA) 2.1 devices to the SFP driver.
There are few differences between TA 2.1 and TA 3.0, especially for
read-only support, so just re-use the existing data.
