Subject: [PATCH v2 2/4] ARM: dts: rockchip: Add CPU resets for RK3128
Date: Tue, 29 Aug 2023 23:40:05 +0200	[thread overview]
Message-ID: <20230829214004.314932-6-knaerzche@gmail.com> (raw)
In-Reply-To: <20230829214004.314932-2-knaerzche@gmail.com>

In order to support bring-up of the non-boot cores, this patch adds the
reset controls for the cpu cores.
They are required/will be used by the Rockchip platsmp driver.
