Subject: [PATCH v2 5/5] arm64: dts: r8a7796-m3ulcb: Disable cpuidle support for CA53 cores
Date: Fri, 18 Jan 2019 11:47:54 +0100 [thread overview]
Message-ID: <1547808474-19427-6-git-send-email-uli+renesas@fpond.eu> (raw)
In-Reply-To: <1547808474-19427-1-git-send-email-uli+renesas@fpond.eu>
From: Takeshi Kihara <takeshi.kihara.df@renesas.com>
The revision of the R8A7796 SoC on the M3ULCB board is ES1.0. This revision
can not use cpuidle for CA53 cores.
Therefore, this patch disables cpuidle support for CA53 cores.
