Some clk gates on Rockchip SoCs are part of the SGRF (secure general
register files) and thus only controllable from secure mode, with the
most prominent example being the watchdog.
In most cases we still want to define this as a real clock though,
to have complete clock tree and not reference the generic base-clock
from the devicetree.
So far we've just defined this as factor-1-1 clocks in the clock init,
so define a special clock-type for it so that this definition can be
part of the general tree-definition and save some boilerplate code.

For 5.3 we had to revert a nice ext4 IO pattern improvement, because it
caused a bootup regression due to lack of entropy at bootup together
with arguably broken user space that was asking for secure random
numbers when it really didn't need to.
See commit 72dbcf7215 (Revert "ext4: make __ext4_get_inode_loc plug").
This aims to solve the issue by actively generating entropy noise using
the CPU cycle counter when waiting for the random number generator to
initialize. This only works when you have a high-frequency time stamp
counter available, but that's the case on all modern x86 CPU's, and on
most other modern CPU's too.
What we do is to generate jitter entropy from the CPU cycle counter
under a somewhat complex load: calling the scheduler while also
guaranteeing a certain amount of timing noise by also triggering a
timer.
I'm sure we can tweak this, and that people will want to look at other
alternatives, but there's been a number of papers written on jitter
entropy, and this should really be fairly conservative by crediting one
bit of entropy for every timer-induced jump in the cycle counter. Not
because the timer itself would be all that unpredictable, but because
the interaction between the timer and the loop is going to be.
Even if (and perhaps particularly if) the timer actually happens on
another CPU, the cacheline interaction between the loop that reads the
cycle counter and the timer itself firing is going to add perturbations
to the cycle counter values that get mixed into the entropy pool.
As Thomas pointed out, with a modern out-of-order CPU, even quite simple
loops show a fair amount of hard-to-predict timing variability even in
the absense of external interrupts. But this tries to take that further
by actually having a fairly complex interaction.
This is not going to solve the entropy issue for architectures that have
no CPU cycle counter, but it's not clear how (and if) that is solvable,
and the hardware in question is largely starting to be irrelevant. And
by doing this we can at least avoid some of the even more contentious
approaches (like making the entropy waiting time out in order to avoid
the possibly unbounded waiting).

The current driver set CC pull up current to 180uA, but FUSB302B was
designed with 80uA for sink detection which means it only guarantee
FUSB302B will works well with that setting. So we change the CC pull
up current to 80uA.

We found that the Type-C OTG cable was plugged in while the system
was suspending, it may fail to detect the Type-C OTG cable after
resume. That's because the fusb302 registers will fail to operate
during suspend, this will cause the fusb302 CC logic to be abnormal.
So we should not operate queue_work function while the suspend.

4.19 kernel will check mode valid before encoder atomic check
when resolution switch. Because when checking mode the
detailed color format and color depth are not considered, some
mode can be mistaken for unsupported, such as 4K-60HZ YUV420 10 bits.
So bus width should be set 8 bits when check mode valid.
