Subject: [PATCH 4/6] ARM: shmobile: r8a7778 dtsi: Use "arm,pl390" for GIC
Date: Fri, 20 Nov 2015 13:36:55 +0100 [thread overview]
Message-ID: <1448023017-21816-5-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1448023017-21816-1-git-send-email-geert+renesas@glider.be>
Replace the "arm,cortex-a9-gic" compatible value for the GIC by
"arm,pl390", as the documentation states it is a PL390.
This has been confirmed by reading the GICD_IIDR register, which reports
0x0000043b (PL390 = 0x00, ARM = 0x43b).
This has no effect on runtime behavior, as currently the GIC driver
treats both compatible values the same.
