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.

This patch removes CONFIG_MTD_SPI_NOR_USE_4K_SECTORS from the default
symbols for the ath79/mikrotik target.
MikroTik devices hold some of their user-configurable settings in the
soft_config partition, which is typically sized 4 KiB, of the SPI NOR
flash memory. Previously, in the ar71xx target, it was possible to use
64 KiB erase sectors but also smaller 4 KiB ones when needed. This is
no longer the case in ath79 with newer kernels so, to be able to write
to these 4 KiB small partitions without erasing 60 KiB around, the
CONFIG_MTD_SPI_NOR_USE_4K_SECTORS symbol was added to the defaults.
However, this ended up making sysupgrade images which were built with
64 KiB size blocks not to keep settings (e.g., the files under
/etc/config/) over the flashing process.
Using 4 KiB erase sector size on the sysupgrade images (by setting
BLOCKSIZE = 4k) allows keeping settings over a flashing process, but
renders the process terribly slow, possibly causing a user to
mistakenly force a manual device reboot while the process is still on-
going. Instead, ditching the 4 KiB erase sectors for the default
64 KiB erase size provides normal SPI write speed and sysupgrade times,
at the expense of not being able to modify the soft_config partition
(which is rarely a required thing).
An OpenWrt patch for MTD_SPI_NOR_USE_4K_SECTORS_LIMIT may once have
allowed to use different per-partition erase sector sizes. Due to
changes on recent kernels it now only works on a per-device basis.
Also, partial eraseblock write can be performed in ath79 with kernels
5.4 and lower, by copying the blocks from the 64 KiB, erasing the whole
sector and restoring those blocks not meant to be modified. A kernel
bump had that patch broken for a long time, but got fixed in bf2870c.
Note: the settings in the soft_config partition can be reset to their
defaults by holding the reset button for 5 seconds (and less than 10
seconds) at device boot.
Fixes: FS#3492 (sysupgrade […] loses settings...)
Fixes: a66eee63368e (ath79: add mikrotik subtarget)

Main part is copied from ar71xx original driver rb91x_nand
written by Gabor Juhos <juhosg@openwrt.org>.
What is done:
* Support of kernel 5.4 and 5.10,
* DTS support,
* New gpio API (gpiod_*) support.

For the targets which enable ubifs, these symbols are already part of the
generic kconfigs. Drop them from the target kconfigs.

This patch enables the SFP cage on the MikroTik RouterBOARD 922UAGS-5HPacD.
GPIO16 (tx-disable-gpios) should be governed by the SFP driver to enable
or disable transmission, but no change is observed. Therefore, it is
left as output high to ensure the SFP module is forced to transmit.
Tested on a RouterBOARD 922UAGS-5HPacD board, with a CISCO GLC-LH-SMD
1310nm module and an unbranded GLC-T RJ45 Gigabit module. PC=>router
iperf3 tests deliver 440/300 Mbps up/down, both via regular eth0 port
or SFP port with RJ45 module. Bridge between eth0 and eth1 delivers
950 Mbps symmetric.

Regulator support was enabled on all subtargets except for ath79-nand.
With Kernel 5.10, AT803x requires Regulator support, thus enabling on
the complete target, as ath79-nand requires AT803x.
While this is only required on Kernel 5.10, enable it also on 5.4. We
have no major size-constraint, so enabling it on 5.4 allows us to clean
up the occurences in the subtarget configuration.

it does not have to be enabled for individual subtargets.

This patch adds support for the MikroTik RouterBOARD RB493G, ported
from the ar71xx target.
See https://routerboard.com/RB493G for details
Specification:
- SoC Qualcomm Atheros AR7161

- Storage: 128MiB NAND
- Ethernet: 9x 1000/100/10 Mbps
- USB 1x 2.0 / 1.0 type A
- PCIe: 3x Mini slot
- MicroSD slot
Working:
- Board/system detection
- Ethernet
- SPI
- NAND
- LEDs
- USB
- Sysupgrade
Enabled (but untested due to lack of hardware):
- PCIe - ath79_pci_irq struct has the slot/pin/IRQ mappings if needed
Installation methods:
- tftp boot initramfs image, scp then flash via "sysupgrade -n"
- nand boot existing OpenWrt, scp then flash via "sysupgrade -n"
Notes:
- initramfs image will not work if uncompressed image size over ~8.5Mb
- The "rb4xx" drivers have been enabled

This commit creates the ath79/mikrotik subtarget in order to support
MikroTik devices based on Qualcomm Atheros MIPS SoCs.
MikroTik devices need a couple of specific features: the split MiNOR
firmware MTD format, which is not used by other devices, and the 4k
sector erase size on SPI NOR storage, which can not be added to the
ath79/generic and ath79/nand subtargets now.
Additionally, the commit moves the two MikroTik devices already in
the generic and nand subtargets to this new one.
Tested on the RB922 board and the wAP AC router.
