From bc968132002687862d58c5708763670132d04a97 Mon Sep 17 00:00:00 2001 From: Bryan Brattlof Date: Tue, 21 Jun 2022 16:36:03 -0500 Subject: [PATCH] soc: soc_ti_k3: identify j7200 SR2.0 SoCs Anytime a new revision of a chip is produced, Texas Instruments will increment the 4 bit VARIANT section of the CTRLMMR_WKUP_JTAGID register by one. Typically this will be decoded as SR1.0 -> SR2.0 ... however a few TI SoCs do not follow this convention. Rather than defining a revision string array for each SoC, use a default revision string array for all TI SoCs that continue to follow the typical 1.0 -> 2.0 revision scheme.
