Subject: [PATCH v2 5/5] ARM: dts: rockchip: Disable non-required timers for RK3128
Date: Tue, 29 Aug 2023 22:37:29 +0200	[thread overview]
Message-ID: <20230829203721.281455-14-knaerzche@gmail.com> (raw)
In-Reply-To: <20230829203721.281455-4-knaerzche@gmail.com>

The Rockchip timer linux driver can handle a maximum of 2 timers and will
get confused if more of them exist.
RK3128 only needs timer0, timer1 and timer5. The latter is the source
for the arm-timer and it's clock is prevented from being disabled in the
clock driver so it can get disabled in the device tree, too.

Fixes: a0201bff6259 ("ARM: dts: rockchip: add rk3128 soc dtsi")
