Subject: [PATCH v3 2/6] ARM: shmobile: r8a7740 dtsi: Add L2 cache-controller node
Date: Mon, 4 May 2015 17:24:28 +0200 [thread overview]
Message-ID: <1430753072-17145-3-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1430753072-17145-1-git-send-email-geert+renesas@glider.be>
Add the missing L2 cache-controller node. This will allow migration to
the generic l2c OF initialization.
The L2 cache is an ARM L2C-310 (r3p1-150rel0), of size 256 KiB (32 KiB x
8 ways).
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

v3:
- Add "arm,shared-override",
v2:
- Fix interrupt (should be 3 cells, not 1),
- Describe cache better.
