/*
When running OpenWrt on MT7623A, I receive a kernel warning as follows (Device dts using mt7623.dtsi): mtk-scpsys 10006000.scpsys: Failed to power on domain mfg WARNING: CPU: 0 PID: 1 at drivers/soc/mediatek/mtk-scpsys.c:457 0xc04a4130 When I switch the device dts to using mt7623a.dtsi, the system fails to boot: rcu: INFO: rcu_preempt detected stalls on CPUs/tasks: rcu: 0-...0: (0 ticks this GP) idle=146/1/0x40000000 softirq=53/53 fqs=1051 (detected by 1, t=2102 jiffies, g=-1111, q=18) Sending NMI from CPU 1 to CPUs 0: Solved the problem by duplicating the power domain of the MT7623 (except MFG) to MT7623A, the system works fine without kernel warnings/errors.
