[PATCH] arm64: dts: k3-j721e: correct cache-sets info

[PATCH] arm64: dts: k3-j721e: correct cache-sets info

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

A72 Cluster 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

So correct the cache-sets info.

Fixes: 2d87061e70dea ("arm64: dts: ti: Add Support for J721E SoC")

Arrgh.. Thank you for fixing this.

I think J7200 also needs fixups. Will cross check and post additional
patches depending on the ones that need it.

Minor comment (should be easy to fix when picking up the patch), lest I
forget-> $subject: arm64: dts: ti: to maintain consistency

I have applied the following to branch ti-k3-dts-next on [1].

Fixed $subject as suggested by Nishanth.

Thank you!

      commit: 7a0df1f969c14939f60a7f9a6af72adcc314675f
 
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.
 
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
 
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
 
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
