As we register regmap irq to manage rk818 irqs, it should
not enable/disable irq by modifying register directly. And
check otg on/off line state before setting new state.

The uart may be reinitialized when resume, if uart is in busy
state, which would fail to configure the baud rate. So reset
and set uart to loopback mode can make sure uart is in idle
state.

When the pointer of hcd is NULL, dwc3 driver will probe again. In this
case the notify sync function will issue "Bad mode in Synchronous Abort
handler detected" error if the extcon notify is not unregisted before
next probe. This patch add unregister extcon notify function and
unregister extcon notify when hcd is NULL.

If the adc drift value is 70, some keys maybe report twice, because
the range of adc_value +/-70 is overlapping other keys' adc range.
So it is better configuring adc drift value from DT, that also can
support more keys at a adc channel. The default adc drift value is
70, if it does not get the drift value from DT.

The probe function of usb controller will remove hcd struct in host
or otg mode, while the hcd is alloced after xhci driver registed. So
there is a logical error if xhci driver is registed after usb
controller and it results in the pointer of hcd point to NULL. This
patch make usb controller probe again if hcd point to NULL.

Per the vendor's requirement, we shouldn't do any setting for
1.8V Signaling Enable, otherwise the interaction/behaviour between
phy and controller will be undefined. Mostly it works fine if we do
that, but we still see failures. Anyway, let's fix it to meet the
vendor's requirement. The error log looks like:

Per JESD84-B51 P69, Host need to change frequency to <=52MHz after
setting HS_TIMING to 0x1, and host may changes frequency to <= 200MHz
after setting HS_TIMING to 0x3. It seems there is no difference if
we don't change frequency to <= 52MHz as f_init is already less than
52MHz. But actually it does make difference. When doing compatibility
test we see failures for some eMMC devices without changing the
frequency to hs_max_dtr. And let's read the spec again, we could see
that "Host may changes frequency to 200MHz" implies that it's not
mandatory. But the "Host need to change frequency to <= 52MHz" implies
that we should do this.

When introducing hs400es, I didn't notice that we haven't
switched voltage to 1V2 or 1V8 for it. That happens to work
as the first controller claiming to support hs400es, arasan(5.1),
which is designed to only support 1V8. So the voltage is fixed to 1V8.
But it actually is wrong, and will not fit for other host controllers.
Let's fix it.

Commit 815806e39b ("regmap: drop cache if the bus transfer error")
added a call to regcache_drop_region() to error path in
_regmap_raw_write(). However that path runs with regmap lock taken,
and regcache_drop_region() tries to re-take it, causing a deadlock.
Fix that by calling map->cache_ops->drop() directly.

maybe vskiplines = 2 on yrgb scl_vop_cal_scale
maybe vskiplines not update on cbcr scl_vop_cal_scale.
Then cbcr path would get vskiplines = 2, that is unexpect.

suspend_prepare can be called during regulator init time also, where
the mutex is not locked yet. This causes a false lockdep warning.
To avoid the problem, remove the lockdep assertion from the function
causing the issue. An alternative would be to lock the mutex during
init, but this would cause other problems (some APIs used during init
will attempt to lock the mutex also, causing deadlock.)

Previous version check all the win, check its yrgb_mst and
enable bit, it wastes too manys times.
We can simple check the vop cfg_done register to sure vop register
take effect. when we have a new config, set cfg_done to 1, then the
cfg_done would auto clear at frame start event. So when cfg_done is
zero, means that there is no pending configs.
