The MP style clocks support an mux with pre-dividers. While the driver
correctly accounted for them in the .determine_rate callback, it did
not in the .recalc_rate and .set_rate callbacks.
This means when calculating the factors in the .set_rate callback, they
would be off by a factor of the active pre-divider. Same goes for
reading back the clock rate after it is set.

Let's configure the keypad in a way where it's usable out of the
box for Linux console use. We want to have the keyboard usable with
Linux console for example when stuck into an initramfs during boot,
for when installing a distro.
As we need to need to have keys mapped in the user space anyways
for some of the keys to match the labels, this non-standard mapping
or usability should be OK.
Some keys don't match the labels either as they don't follow the PC
keyboard style. For example we have "shift + ," produce "<", and
"shift + ." produce ">" instead of ";" and ":".
So let's follow the standard PC keyboard layout for ctrl, shift and
alt keys:
Ctrl = what is labeled as shift
Alt = what is labeled as SYM
Shift = what is lableled as caps lock
This way we have Ctrl key for console use. Who knows where they got
the caps lock idea.. Probably from some focus group popularity vote
or something.
For the OK key, let's keep it as the useless KEY_OK unless we can
come up with some standard mapping for it we can stick with.
We have at least Esc, Delete, Meta, and Page Down keys missing, but
none of them seem to be better than others. PC keyboard often has
Page Down in that location. Esc would be probably the most usable
one when installing a Linux distro but is the opposite of OK.
Note that the LCD keys are just touchscreen hot spots, so I'm not
sure if the driver or hardware allows setting them up as keys for
the console.
Anyways, the rest can be mapped in the user space.

We were reading clock rate directly from device tree "clock-frequency"
property of corresponding clock node in show_cpuinfo function.
Such approach is correct only in case cpu is always clocked by
"fixed-clock". If we use clock driver that allows rate to be changed
this won't work as rate may change during the time or even
"clock-frequency" property may not be presented at all.
So this commit replaces reading device tree with getting rate from clock
driver. This approach is much more flexible and will work for both fixed
and mutable clocks.

able to get clock for core[0]. That was because only one cpu@0 node was
represented in ARC HS device tree and it was impossible to get clock for

So as ARC HS may have up to 4 cores we update device tree to match
maximum possible cores quantity.

The PMU Cortex M0 on rk3399 is intended to be used for things like
DDRFreq transitions, suspend/resume, and other things that are the
purview of ARM Trusted Firmware and not the kernel. As such, the
kernel shouldn't be messing with the clocks. Add CLK_IGNORE_UNUSED to
these clocks.
Without this change, the following was observed on a Chromebook with a
rk3399 (using not-yet-upstream ARM Trusted Firmware code and
not-yet-upstream kernel code based on kernel-4.4):
1. We init the clock framework.
2. We start up "DDRFreq", which causes ATF to occasionally fire up the
M0 for transitions. Each time ATF fires up the M0 it will turn on
these clocks and each time it is done it will turn them off.
3. We finally get to the the part of the kernel that calls
clk_disable_unused() and we disables the clocks.
You can see the race above. Basically everything is fine as long as
ARM Trusted Firmware isn't starting up the M0 at exactly the same time
that the kernel is disabling unused clocks. ...but if the race
happens then we go boom.

The MiQi board's green LED doesn't work at all with the mainline kernel.
There are multiple reasons to this. First, the gpio number is wrong, it
is declared on gpio220 (chip 7 pin 4) instead of gpio218 (chip 7 pin 2).
Second, a pinctrl is referenced, also declared with the same wrong value
while it is not unused. Third, the GPIO polarity was wrong (active low
instead of active high) with the default value set to "default-on",
resulting in the LED being turned off even when the GPIO is correct.
This patch fixes all these inconsistencies at once since these they are
related to each other, and also restores the "timer" trigger which is
the same as the one used by the kernels shipped with the board.
It's important to note that during the port to mainline, the led's label
was changed from "System" to "miqi:green:user", so scripts making use of
the name will still not work until they're fixed.

The code responsible for splitting periods into chunks that
can be handled by the DMA controller missed to update total_len,
the number of bytes processed in the current period, when there
are more chunks to follow.
Therefore total_len was stuck at 0 and the code didn't work at all.
This resulted in a wrong control block layout and audio issues because
the cyclic DMA callback wasn't executing on period boundaries.
Fix this by adding the missing total_len update.
