This commit add a workaround for non working SGMII link observed on some
QCA956x SoCs. The workaround originates part from the U-Boot source code
from QCA, part from the implementation from TP-Link found in the GPL
tarball for the EAP245v1.
Extends commit 0d416a8d3b990e3b78628f0e7546527709c877f7 for QCA956x.
Note that reset is the same on QCA955x and QCA956x, same register offset
and values.

This adds 3 Mikrotik rb4xx series drivers as follows:
rb4xx-cpld: This is in the mfd subsystem, and is the parent CPLD device
that interfaces between the SoC SPI bus and its two children below.
rb4xx-gpio: This is the GPIO expander.
rb4xx-nand: This is the NAND driver.
The history of this code comes in three phases.
1. The first is a May 2015 attempt to push the equivalient ar71xx rb4xx
drivers upstream. See https://lore.kernel.org/patchwork/patch/940880/.

Between 4.19 and 5.4, mtd parsers have been moved to "parsers"
subdirectory. Like for myloader.c in the previous patch,
this patch moves tplinkpart.c to the kernel patches, so the

the path can be adjusted per kernel.

The ag71xx driver from Linux 5.4 currently has various shortcomings
when used with OpenWrt compared to our downstream version.
For example, the upstream driver does not support modifying the ethernet
clock and configuring RGMII delays on the MAC side.
While we should certainly switch to the upstream driver, the amount of
necessary patches would make it cumbersome to work with. It's also
highly likely we won't be able to finish patching the upstream driver in
time for a Linux 5.4 release.
Tested on Siemens WS-AP3610.

This commit adds a workaround for the loss of the SGMII link observed on
the QCA955x generation of SoCs. The workaround originates part from the
U-Boot source code, part from the implementation from AVM found in the
GPL tarball for the AVM FRITZ!WLAN Repeater 450E.
The bug results in a stuck SGMII link between the PHY device and the SoC
side. This has only been observed with the Atheros AR8033 PHY and most
likely all devices using such combination are affected.
It is worked around by reading a hidden SGMII status register and
issuing a SGMII PHY reset until the link becomes useable again.

This patch contains updated driver for Atheros NAND Flash Controller
written originally by Gabor Juhos for ar71xx (aka 'ar934x-nfc').
ath79 version has adapted to work with kernel 4.19 and Device Tree.
It has also been renamed to 'ar934x-nand' to avoid confusion with
Near-Field Communication technology.
Controller is present on Atheros AR934x SoCs and required for accessing
internal flash storage on routers like Netgear WNDR4300.
This port preserves all NAND programming code while moving platform
configuration to Device Tree and replacing some kernel functions marked
for retirement by 4.19.
Suitable definition is included in 'ar934x.dtsi' ('nand@1b000200' section).
Most important changes to ar71xx version are:
* old kernel sections of code removed
* 'bool swap_dma' provided by platform data is now set by boolean DT
property 'qca,nand-swap-dma'
* board-supplied (mach-*.c code) platform data removed - its elements
become either unused, redundant or replaced by DT methods (like reset)
* IRQ is reserved by devm_request_irq() so free_irq() is not needed anymore
* calls to deprecated nand_scan_ident() + nand_scan_tail() function pair
replaced by using recommended nand_scan() with attach_chip() callback
* ECC is set to hardware by default, can be overriden by standard DT
'nand-ecc-*' properties (software Hamming or BCH are other options)
This driver has been successfully tested on Netgear WNDR4300 running
experimental ath79 OpenWrt master branch.

Upstream commit 246902bdf562d45ea3475fac64c93048a7a39f01
Which contains following explanation:
--
There is no need to use GFP_ATOMIC here, GFP_KERNEL should be enough.
The 'kcalloc()' just a few lines above, already uses GFP_KERNEL.
--
Looking at the code, all other descriptors also use plain GFP_KERNEL

ethtool doesn't work currently as phy_ethtool_ioctl expects user space
pointer, but it's being passed kernel one. Fixing it doesn't make sense
as {s,g}et_settings were deprecated anyway. So let's rather remove
phy_ethtool_ioctl and use new {s,g}et_link_ksettings instead. While at
it, update nway_reset as well.

be very dangerous on loaded hosts, since the cpu
calling ndo_poll_controller() might steal all NAPI
contexts (for all RX/TX queues of the NIC).
This capture, showing one ksoftirqd eating all cycles
can last for unlimited amount of time, since one
cpu is generally not able to drain all the queues under load.
It seems that all networking drivers that do use NAPI
for their TX completions, should not provide a ndo_poll_controller() :
Most NAPI drivers have netpoll support already handled
in core networking stack, since netpoll_poll_dev(
uses poll_napi(dev) to iterate through registered
NAPI contexts for a device.

While converting Nanostation M XW from current ar71xx code to ath79 I've
hit one issue, where the ethernet networking wasn't working, so I was
checking every bit in the networking setup path between ar71xx and
ath79.
I've came to the following code in ar71xx/mach-ubnt-xm.c:
static void __init ubnt_xw_init(void) {
...
ath79_setup_ar934x_eth_cfg(AR934X_ETH_CFG_MII_GMAC0 |
AR934X_ETH_CFG_MII_GMAC0_SLAVE);
...
}
Where this code is setting AR934X_ETH_CFG_MII_GMAC0_SLAVE bit in
AR934X_GMAC_REG_ETH_CFG register, but I couldn't find a way of setting
this bit from DTS, so this patch adds `mii-gmac0-slave` DTS property
which allows setting of this bit in `gmac-config`, which is then used in
Nanostation M XW DTS.

On ar933x and later chips, there are separated mac/mdio resets, but
resetting the entire gmac block with register values requires both
mac_reset and mdio_reset to be asserted together.
Add support for optional mdio reset so that we can do a full reset
if needed.
This patch also replaced deprecated devm_reset_control_get for
mac reset.
To use this feature, the following is needed:
1. drop "simple-mfd" compatible to register mdio0 after gmac init
so that mdio registers aren't reset after initialization.
2. move mdio reset from mdio-bus to its parent eth node.
NOTE: This can't be applied on gmac1 with builtin switch since we
haven't add a feature to defer probe if phy connection failed.

Also add a space in mode printing to make it look better.

On ath79 and UBNT Bullet M XW (ar9342) I was experiencing weird issues during
network setup[1] which I was able to reproduce easily with following commands:
uci set network.lan.ipaddr='192.168.1.20'
uci commit network
ifup lan
Which resulted after some time in:
...
WARNING: CPU: 0 PID: 0 at net/sched/sch_generic.c:461 dev_watchdog+0x16c/0x280
NETDEV WATCHDOG: eth0 (ag71xx): transmit queue 0 timed out
...
Sometimes I wasn't able to use networking anymore, sometimes it was enough to
just ifdown/ifup lan and network was backup. On ar71xx it was all working just
fine.
I've found out, that it was happening because ag71xx_poll() wasn't called, thus
the TX queue wasn't emptied. The ag71xx_poll() is being called from napi
hrtimer, which is enabled by napi_schedule() in ar71xx_interrupt(), but since
no interrupts were ever fired again after ag71xx_stop() was called, it was
always leading to tx queue timeouts:
*** ag71xx_hard_start_xmit()
eth0: packet injected into TX queue
eth0: raw intr=00000001 TXPS POLL
eth0: enable polling mode
eth0: processing TX ring, flush=no
eth0: disable polling mode, rx=1, tx=1,limit=32
( `ifup lan done here` )
*** ag71xx_stop()
*** ag71xx_open()
*** ag71xx_hw_enable()
IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
*** ag71xx_hard_start_xmit()
eth0: packet injected into TX queue
*** ag71xx_hard_start_xmit()
eth0: packet injected into TX queue
...
WARNING: CPU: 0 PID: 0 at net/sched/sch_generic.c:320 dev_watchdog+0x164/0x274
So I've looked at ag71xx_stop() in ar71xx, added the missing bits to ath79 and
fixed this issue.

Currently it's quite hard to diff debugging output between ar71xx and
ath79, so this patch tries to improve it by adding the same
ag71xx_dump_regs function and placing debugging output from the
registers to relatively same places.

This patch ports the cybertan_part code from ar71xx and converts the
driver to a DT-supported mtd parser. As a result, it will no longer
add the u-boot, nvram and art partitions, which were never part of
the special Cybertan header.
Instead these partitions have to be specified in the DT, which has the
upside of making it possible to add properties (i.e.: read-only), labels
and references to these important partitions.

Without "syscon" being present in an ag71xx ethernet DT node's
compatible property, a panic occurs at boot during probe citing
"Unhandled kernel unaligned access".
With this modification, the panic no longer occurs and instead the probe
simply fails, allowing the boot process to continue.

We currently don't have any code configuring interface mode in ath79,
meaning that we relies on bootloader to set the correct interface mode.
This patch added code to set interface correctly so that everything works
even if bootloader configures it wrong.(e.g. on WNDR3800 u-boot set
the second GMAC mode to RMII but it should be RGMII.)
Introduced "qca,mac-idx" for the difference in MII_CTRL register value.

Some AR9344 boards do very poorly with the default settings and
need custom rxdv-delay, rxd-delay, txd-delay, txen-delay flags
to perform reasonably.
In this case the WD My Net Wi-Fi Range Extender can not even
manage 10Mbps on a 1Gbit link:

with but with the correct settings in place, it does much better:
