Subject: [PATCH v2 3/5] arm64: dts: r8a7796: Add CA53 L2 cache-controller node
Date: Tue,  7 Mar 2017 19:03:24 +0100	[thread overview]
Message-ID: <1488909806-3322-4-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1488909806-3322-1-git-send-email-geert+renesas@glider.be>

Add a device node for the Cortex-A53 L2 cache-controller.

The L2 cache for the Cortex-A53 CPU cores is 512 KiB large (organized as
32 KiB x 16 ways).

Extracted from a patch by Takeshi Kihara in the BSP.

Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
