Image for RB912UAG-2HPnD supports the 5GHz variant without
modifications. Add it as alternative name, so it can be found easier.
While at that, adjust board display name in device tree, to reflect
that.

This fixes reference clock frequency of RB912. 25 MHz frequency leads
to system clock running too fast, uptime incrementing too fast and
delays (like `sleep 10`) returning too early.
Board has quartz with NSK 3KHAA Z 40 000 marking.

For some reason useless labels and aliases have been propagated through
copy-paste. Before the issue spreads any further, this patch cleans up
all relevant DTS files to the canonical form, bringing ath79 in line
with other mikrotik platforms (ramips and ipq40xx).

On MikroTik RB91x board series a reset key shares SoC gpio
line #15 with NAND ALE and NAND IO7. So we need a custom
gpio driver to manage this non-trivial connection schema.
Also rb91x-nand needs to have an ability to disable a polling
of the key while it works with NAND.
While we've been integrating rb91x-key into a firmware, we've
figured out that:
* In the gpio-latch driver we need to add a "cansleep" suffix to
several gpiolib calls,
* When gpio-latch and rb91x-nand fail to get a gpio and an error
is -EPROBE_DEFER, they shouldn't report about this, since this
actually is not an error and occurs when the gpio-latch probe
function is called before the rb91x-key probe.
We fix these related things here too.

It was reported that some rb912 boards (ar934x) have issues with some ethernet speeds.
Investigation shows that the board failed to adapt the ethernet pll values as shown here:
[ 5.284359] ag71xx 19000000.eth: failed to read pll-handle property
added custom prints in code and triggering a link switch:
[ 62.821446] Atheros AG71xx: fast reset
[ 62.826442] Atheros AG71xx: update pll 2
[ 62.830494] Atheros AG71xx: no pll regmap!
Comparison with another very similar board (rb922 - QCA955x) showed a missing
reference clock frequency in dts, which seems to cause a pll init issue.
Unfortunately, no errors are printed when this occurs.
Adding the frequency property fixes the pll init as it can be parsed now
by the ethernet driver.
[ 55.861407] Atheros AG71xx: fast reset
[ 55.866403] Atheros AG71xx: update pll 2
[ 55.870462] Atheros AG71xx: ath79_set_pllval: regmap: 0x81548000, pll_reg: 0x2c, pll_val: 0x02000000

Analysis done by Denis Kalashnikov:
It seems that some ROS versions on some routerboard models have this bug:
after silence boot (no output to uart, no beeps) beeper clicks when wireless traffic is.
https://forum.mikrotik.com/viewtopic.php?f=3&t=92269https://forum.mikrotik.com/viewtopic.php?t=63399
From these links:
1)
Hello, I have RB951G-2HnD and I noticed strange thing
when I loaded the device with some wireless traffic it
produced strange sound - like hissing, fizzing etc.
2)
Same problem still on 6.33, with silent boot enabled
I hear buzzing noise on wireless load.
3)
The sound is fixed in v5.19, it was a bug that caused beeper to make clicks.
It also got fixed in RouterOS:
* What's new in 5.19 (2012-Jul-16 10:51):
fix ticking sound on RB411UAHL;
* What's new in 6.38.3 (2017-Feb-07 09:52):
rb3011 - fixed noise from buzzer after silent boot;
I've checked with an oscilloscope that:
* When on the ssr beeper pin is 0,
on the beeper itself is 1 (~5V),
and when on the ssr beeper pin is 1,
on the beeper is 0
The beeper doesn't consume power,
so 1 should be a default/idle value for the ssr beeper pin).
* When there is wireless traffic (ping packets)
in the background and the beeper clicks, I see
pulses on the beeper itself,
but no pulses on the ssr beeper pin (Q5 pin of 74hc595).
When I manually toggle the ssr beeper pin I see pulses on both.
So, it is likely that the phantom beeper clicks are caused by the EMI.

This board has been supported in the ar71xx.
Links:
* https://mikrotik.com/product/RB912UAG-2HPnD
* https://openwrt.org/toh/hwdata/mikrotik/mikrotik_rb912uag-2hpnd
This also supports the 5GHz flavour of the board.
Hardware:
* SoC: Atheros AR9342,
* RAM: DDR 64MB,
* SPI NOR: 64KB,
* NAND: 128MB,
* Ethernet: x1 10/100/1000 port with passive POE in,
* Wi-Fi: 802.11 b/g/n,
* PCIe,
* USB: 2.0 EHCI controller, connected to mPCIe slot and a Type-A
port -- both can be used for LTE modem, but only one can be
used at any time.
* LEDs: 5 general purpose LEDs (led1..led5), power LED, user LED,
Ethernet phy LED,
* Button,
* Beeper.
Not working:
* Button: it shares gpio line 15 with NAND ALE and NAND IO7,
and current drivers doesn't easily support this configuration,
* Beeper: it is connected to bit 5 of a serial shift register
(tested with sysfs led trigger timer). But kmod-gpio-beeper
doesn't work -- we left this as is for now.
Flashing:
* Use the RouterBOARD Reset button to enable TFTP netboot,
boot kernel and initramfs and then perform sysupgrade.
* From ar71xx OpenWrt firmware run:
$ sysupgrade -F /tmp/<sysupgrade.bin>
