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.

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.

All other SoC DTSI files have gpio enabled by default, only
ar9330/ar9331 disable it by default, only to have it enabled again
afterwards for each individual device.
So, do not disable it in the first place, and drop all device-specific
status statements afterwards.

ar933x appears to have the same spi controller as ar934x but it's
not mentioned in datasheet at all. Use new spi driver instead to
gain more flash operating performance.

There are several cases where phy-mode and status properties are
set again in DTS(I) files although those were set to the same values
in parent DTSI files already. Remove those cases (and thus also stop
their proliferation by copy/paste).

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.

In commit e9652e1696 ("ath79: fix pinmux for ar933x devices") I've
wrongly changed desired register value to 0xf8 although it should've
been set to 0x0.
0xf8 value sets bits 3-7 (ETH_SWITCH_LEDx_EN) to 1 which actually
enables ethernet switch LEDs, so 0x0 is correct value in order to use
the pins as GPIO.

Properly disable the SoC's internal Switch LEDs on the pinmux.
Devices that previously called ath79_gpio_function_disable for
the switch LEDs, just need to reference switch_led_pins in the
pinctrl-0 property of the gpio-leds node.

Allow specifying desired mdio clock frequency in dts.
Use default frequency around 5MHz for builtin switch and 2MHz for other mdio bus.

gmac0 is always connected to switch phy4 and mdio1 is always needed.
So add phy handle for eth0 and enable mdio1 by default.
Move fixed-link for gmac1 from device dts to ar9331.dtsi because gmac1 is always connected to builtin switch.

Some maintainers prefer DTS files licensed under permissive license like
MIT / BSD. As all DT bindings should be OS independent and DTS files are
pretty separated from Linux code it probably makes sense to share them
across projects.
The safest solution is to use dual licensing: that way it stays clear
these files can be used in GPL projects without depending on current
belief of licenses compatibility.
