From 33a1c6618677fe33f8e84cb7bedc45abbce89a50 Mon Sep 17 00:00:00 2001

Subject: [PATCH] nvmem: sfp: Add support for TA 2.1 devices
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.
