Subject[PATCH 5.10 125/563] arm64: dts: ti: k3-j7200: Fix the L2 cache sets
Date
From: Nishanth Menon <nm@ti.com>

[ Upstream commit d0c826106f3fc11ff97285102b576b65576654ae ]

A72's L2 cache[1] on J7200[2] is 1MB. A72's L2 is fixed line length of
64 bytes and 16-way set-associative cache structure.

1MB of L2 / 64 (line length) = 16384 ways
16384 ways / 16 = 1024 sets

Fix the l2 cache-sets.
