From a172c86931709d6663318609d71a811333bdf4b0 Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Fri, 12 Nov 2021 22:26:40 -0600 Subject: arm64: dts: ti: k3-j7200: Correct the d-cache-sets info A72 Cluster (chapter 1.3.1 [1]) has 48KB Icache, 32KB Dcache and 1MB L2 Cache - ICache is 3-way set-associative - Dcache is 2-way set-associative - Line size are 64bytes 32KB (Dcache)/64 (fixed line length of 64 bytes) = 512 ways 512 ways / 2 (Dcache is 2-way per set) = 256 sets. So, correct the d-cache-sets info.
