[PATCH 14/31] ARM: dts: rockchip: Disable non-required timers for RK3128
From: Alex Bee <hidden>
Date: 2023-08-29 17:19:21
Also in:
alsa-devel, dri-devel, linux-arm-kernel, linux-clk, linux-phy, linux-rockchip, lkml
Subsystem:
arm/rockchip soc support, the rest · Maintainers:
Heiko Stuebner, Linus Torvalds
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 its 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")
