0494278073 ath79: resolve GPIO address conflicts
The ar71xx GPIO driver only uses 0x24 registers, all following GPIO
registers are using to control pinmux functions, which are not handles
by the GPIO driver but the generic Linux pinctrl driver.

For some SoC conflicting address ranges were defined for these (AR7240 &
AR9330).

Resolve these cases and align the address space of the GPIO controller
between all SoCs, as the used address space of the driver is identical
for all these.

3a4b751110 ath79: enable UART in SoC DTSI files
The uart node is enabled on all devices except one (GL-USB150 *).
Thus, let's not have a few hundred nodes to enable it, but do not
disable it in the first place.

Where the majority of devices is using it, also move the serial0
alias to the DTSI.

*) Since GL-USB150 even defines serial0 alias, the missing uart
   is probably just a mistake. Anyway, disable it for now so this
   patch stays cosmetic.

cea169702c ath79: remove ar934x MDIO reset from MAC node
Remove the MDIO reset from the MAC mode for the AR934x SoC family.
The reset is currently also defined for the MDIO node, where the reset
is acquired exclusively.

In case the ethernet node is enabled, this triggers a warning, as the
reset is already acquired by the MAC.

AR934x chips also got the 'old' qca,ar9330-uart in addition to the
'new' ns16550a compatible one. Add support for UART1 clock selector as
well as device-tree bindings in ar934x.dtsi to make use of that uart.

ebf0d8dade ath79: add new ar934x spi driver
A new shift mode was introduced since ar934x which has a way better
performance than current bitbang driver and can handle higher spi
clock properly. This commit adds a new driver to make use of this
new feature.
This new driver has chipselect properly configured and we don't need
cs-gpios hack in dts anymore. Remove them.

bda6b6144d ath79: ar934x: use reset for usb-phy-analog
This was already available on ar71xx, but is missing on ath79.
This solves the slow usb speed on TP-Link WDR3600/WDR4300 and similar,
as reported in Flyspray [0], OpenWRT Forum [1] and GitHub PR [2].

758a4d1766 ath79: add AR934x NAND Flash Controller driver
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.

8dde11d521 ath79: dts: drop "simple-mfd" for gmacs in SoC dtsi
With a proper probe deferring for ag71xx we don't need to explicitly
probe mdio1 before gmac0.
Drop all "simple-mfd" in SoC dtsi so that gmac orders can be the same
as ar71xx.
This makes eth0/eth1 order the same as those in ar71xx, which means
we don't need a migration script for this anymore and we can merge
incorrectly split gmac/mdio driver back together.
