on the upstream, and we need to these feature for Rockchip Release
Platform. Let's support them.

All of the sched domains will be destroied and then rebuilded when a cpu
online/offline, if a softirq comes after the shced domains are destroied,
this cpu will be stucked in the infinite loop in sched_group_energy(),
because of it can not get the shced donmain in for_each_domain(cpu, sd).

It will cause deadlock and while(1) if call printk while schedule

cpu0(hold the console sem):
printk->console_unlock->up_sem->spin_lock(&sem->lock)->wake_up_process(cpu1)
->try_to_wake_up(cpu1)->while(p->on_cpu).
cpu1(request console sem):
console_lock->down_sem->schedule->idle_banlance->update_cpu_capacity->
printk->console_trylock->spin_lock(&sem->lock).
p->on_cpu will be 1 forever, because the task is still running on cpu1,
so cpu0 is blocked in while(p->on_cpu), but cpu1 could not get
spin_lock(&sem->lock), it is blocked too, it means the task will running
on cpu1 forever.

The hardware-tracked trips will set the alarm interrupt value for
registers. Then when the thermal zone has no trips to be set,
That make the thermal trips callback a over range value.
The root cause is the rk_tsadcv2_temp_to_code() function to handle the
invalid temperature range is indeed incorrect, let's fix it on now.
Otherwise, the thermal alarm interrupt will be triggered all the time
on some SoCs.
Fox example:
localhost tmp # grep thermal /proc/interrupts; sleep 5;
grep thermal /proc/interrupts

Due to there are only two vop module, that's to say we can't keep
enable eDP / LVDS / HDMI at the same time, so this time we still
keep LVDS device disabled. If you want to enable lvds device,
then you should disable the HDMI or eDP device, and enable the
LVDS device.
And one more thing that eDP panel and LVDS panel can't enable at
the same time, cause both of them have the same enable gpio. If
you still want to do this, there is an hack way that delete the
'enable-gpios' comptabile from 'lvds-panel'.
