Make changes to provide ioctl-interface to interact with

commit 7a4408c6bd3e ("binder: make sure accesses to proc/thread are
safe") made a change to enqueue tcomplete to thread->todo before
enqueuing the transaction. However, in err_dead_proc_or_thread case,
the tcomplete is directly freed, without dequeued. It may cause the
thread->todo list to be corrupted.
So, dequeue it before freeing.

The current implementation of synchronize_sched_expedited() incorrectly
assumes that resched_cpu() is unconditional, which it is not. This means
that synchronize_sched_expedited() can hang when resched_cpu()'s trylock
fails as follows (analysis by Neeraj Upadhyay):
o CPU1 is waiting for expedited wait to complete:
sync_rcu_exp_select_cpus
rdp->exp_dynticks_snap & 0x1 // returns 1 for CPU5
IPI sent to CPU5
synchronize_sched_expedited_wait
ret = swait_event_timeout(
rsp->expedited_wq,
sync_rcu_preempt_exp_done(rnp_root),
jiffies_stall);
expmask = 0x20 , and CPU 5 is in idle path (in cpuidle_enter())
o CPU5 handles IPI and fails to acquire rq lock.
Handles IPI
sync_sched_exp_handler
resched_cpu
returns while failing to try lock acquire rq->lock
need_resched is not set
o CPU5 calls rcu_idle_enter() and as need_resched is not set, goes to
idle (schedule() is not called).
o CPU 1 reports RCU stall.
Given that resched_cpu() is now used only by RCU, this commit fixes the
assumption by making resched_cpu() unconditional.

We need the scheduler's fastpaths to be, well, fast, and unnecessarily
disabling and re-enabling interrupts is not necessarily consistent with
this goal. Especially given that there are regions of the scheduler that
already have interrupts disabled.
This commit therefore moves the call to rcu_note_context_switch()
to one of the interrupts-disabled regions of the scheduler, and
removes the now-redundant disabling and re-enabling of interrupts from
rcu_note_context_switch() and the functions it calls.

which is holding spinlock and in the meantime dwc3_interrupt

deadlock.
This change disables the interrupts when spinlock is acquired
in gsi_ctrl_clear_cpkt_queues function.

On 8996 AUTO platform, too many "hdmi_i2c_xfer" warnings appear
when booting that makes boot time longer and may cause watchdog
bite. The warning is generated by WARN_ON() in hdmi_i2c_xfer()
which prints call stack like:
hdmi_i2c_xfer+0x44/0x398
__i2c_transfer+0x270/0x4b4
i2c_transfer+0x64/0xb0
hdmi_ddc_read+0x84/0xdc

kthread_worker_fn+0xcc/0x170
kthread+0xf8/0x100
ret_from_fork+0x10/0x20
The reason is the HDMI_CTRL_ENABLE bit of REG_HDMI_CTRL register
is disabled during the reset by the first commit. This reset is
caused by the missing of HPD regulator enabling in HPD call sequence.
So to remove the HDMI i2c warning, the patch enables HPD regulator
to avoid the reset.

When the source is powered off with an external sink connected, it
will result in a call to blank and power off the source. In the
current implementation, sink is not transitioned to D3 power mode
prior to turning off the source. This can result in the sink
reporting signal lock failures as the source if powered off,
resulting in an HPD IRQ interrupt. If this interrupt is handled
after the DP controller is powered off, it can lead to unclocked
register accesses. Fix this by ensuring that sink is powered off
prior to powering off the source. In addition, ensure that no more
attention events are handled once the DP controller is powered off.

DWC3 driver uses wakeup_source and allows pm_suspend only after
entering low power mode as part of runtime suspend. This prevents
PM suspend in host mode if connected device's driver doesn't
support runtime or selective suspend.
Add support in driver where user can specify using dtsi attribute
to not use wakeup source in host mode. It will allow system to enter
deep sleep or pm_suspend irrespective of runtime PM state of XHCI.
On high level below are the changes in default behavior:
-Do not use wakeup_source for DWC3 when operating in host mode.
-For host mode, devices will suspend upon PM suspend and resumed
after PM resume.
