ARM: dts: rockchip: disable arm_global_timer on rk3066 and rk3188
stable inclusion from stable-v5.10.159 commit 96b43f36a593cdc6b7984ba8d543b660c0b507a0 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7NTXH Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=96b43f36a593cdc6b7984ba8d543b660c0b507a0 -------------------------------- [ Upstream commit da74858a ] The clock source and the sched_clock provided by the arm_global_timer on Rockchip rk3066a/rk3188 are quite unstable because their rates depend on the CPU frequency. Recent changes to the arm_global_timer driver makes it impossible to use. On the other side, the arm_global_timer has a higher rating than the ROCKCHIP_TIMER, it will be selected by default by the time framework while we want to use the stable Rockchip clock source. Keep the arm_global_timer disabled in order to have the DW_APB_TIMER (rk3066a) or ROCKCHIP_TIMER (rk3188) selected by default.
