Subject: [PATCH v4 1/2] arm64: dts: r8a7795: Add Cortex-A53 CPU cores
Date: Fri, 24 Feb 2017 14:59:27 +0100	[thread overview]
Message-ID: <1487944768-31983-2-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1487944768-31983-1-git-send-email-geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org>

This patch adds Cortex-A53 CPU cores to r8a7795 SoC for a total of 8
cores (4 x Cortex-A57 + 4 x Cortex-A53).

Based on work by Takeshi Kihara and Dirk Behme.

Signed-off-by: Geert Uytterhoeven <geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org>

v4:
  - Drop bogus links from the pmu_a57 node to the CA53 nodes,

v3:
  - Link CPU nodes 100-103 to their L2 cache nodes,

v2:
  - Rebased.
