We don't have the display engine driver commited in FreeBSD yet so it is
useless to expose the clocks yet (and also it have not been tested on H5).

Allwinner H3 and H5 share many internal components, that's why they can
use the same drivers.
This patch adds the compatible strings to enable clock drivers
probing on Allwinner NanoPI NEO2 device.

Due to three conditions the codec driver for Allwinner A10/A20 and H3/H5 did not work properly here:
Wrong bit position for the analog audio reset
Hardware Reset of codec was not de-asserted correctly
Linux DTS file did not contain the address of the analog register the way as the driver was expecting it.
This patch proposes fixes for those three parts.

The old clocks are disconneted from the build since r337344.
Remove all those pseudo drivers. The only one remaining is for gmac
(the ethernet controller) so move it to sys/arm/allwinner.
While here remove a83t support from gmacclk as it is unneeded since r326114.

Since 5.0 DTS the syscon controller have a new compatible as it
exports new subnodes, we currently only use it as a syscon provider
so just add the new compatible.

Since latest DTS update the rtc is supposed to register two clocks :
- osc32k (the 32k oscillator on the board that the RTC uses directly and
that other peripheral can use)
- iosc (the internal oscillator of the RTC when available which frequency
depend on the SoC revision)
Since we need the RTC before the proper clock control unit (because it uses
those clocks) attach it a BUS_PASS_BUS + MIDDLE and attach the clock control
unit at BUS_PASS_BUS + LAST for the SoC that requires it.

If a custom block size requested, use it, otherwise revert to the previous logic
of using just a data size if it's less than MMC_BLOCK_SIZE, and MMC_BLOCK_SIZE otherwise.

Using DFLTPHYS/MAXPHYS is not always OK, instead make it possible for the
controller driver to provide maximum data size to MMCCAM, and use it there.
The old stack already does this.

When comparing best frequencies use the absolute value.
If we do not do that we end up choosing an always lower value than

U-Boot will leave the ephy reset de-asserted and the MAC soft reset will
fail on these boards with internal PHY and no link established. Toggle reset
again before proceeding to attach/init.
MFC after: 1 week
This was intended to fix the soft reset timeout on boot for OrangePi One/R1
with internal PHY, but seems to cause other problems later on due to soft
resetting around some state changes that may or may not make the NIC
non-functional.
Reverting this for now while a better solution is sought out.
From NetBSD: Since the MAC can get stuck in reset state with no link, ignore
reset timeouts and continue with initializing the device.
Fixes "soft reset timeout" issue at boot with no network cable plugged in.
awg_init may be called multiple times throughout normal interface usage, so
the tx/rx descriptor base address registers must be written after each MAC
reset and are moved as such.
This problem has been observed on FreeBSD, H3/H2+ devices with an internal
PHY (includes OrangePi R1, OrangePi One at least).

error in the function hypercall_memfree(), where the wrong arena was being

Introduce a per-page flag, VPO_KMEM_EXEC, to mark physical pages that are
mapped in kmem with execute permissions. Use this flag to determine which
arena the kmem virtual addresses are returned to.
Eliminate UMA_SLAB_KRWX. The introduction of VPO_KMEM_EXEC makes it

a10_timer is currently use in UP allwinner SoC (A10 and A13).
Those don't have the generic arm timer.
The arm generic timecounter is broken in the A64 SoC, some attempts have
been made to fix the glitch but users still reported some minor ones.
Since the A64 (and all Allwinner SoC) still have this timer controller, rework
the driver so we can use it in any SoC.
Since it doesn't have the 64 bits counter on all SoC, use one of the
generic 32 bits counter as the timecounter source.

Recent DTS use the syscon for the emac controller.
We support this but since U-Boot is still using old DTS it was never
needed for us to add this support, but this is a problem when using upstream
recent DTS and will be when U-Boot will catch up.
While here add a new compatible to the aw_syscon driver as Linux changed it ...
Now that aw_sid expose nvmem interface, use that to read the calibration
data.
Add support for H5 SoC.
Fix the bindings, we used to have non-upstreamed bindings. Switch to the
one that have been sent upstream. They are not stable yet, so we switch
from custom, wrong, bindings to correct, proposed bindings
Rework aw_sid so it can work with the nvmem interface.
Each SoC expose a set of fuses (for now rootkey/boardid and, if available,
the thermal calibration data). A fuse can be private or public, reading private
fuse needs to be done via some registers instead of reading directly.
Each fuse is exposed as a sysctl.
For now leave the possibility for a driver to read any fuse without using
the nvmem interface as the awg and emac driver use this to generate a mac
address.
It doesn't work since 2 years when we stopped patching DTS.
The DTS now have the correct bindings but they are a lot different
from our hacked ones we used to have (and more representative of the
reality).
Remove the old clocks for allwinner as now all the SoCs have been converted
to clkng.
The only old clock now is the gmac clock which still lives under the /clocks
dts node.
