arm64: dts: amlogic: Assign a fixed index to mmc devices

Pin them to fixed values to ease booting in environments where UUIDs

https://patchwork.kernel.org/patch/11747669/

Commit message taken from commit 0011c6d18277 ("arm64: dts: rockchip: Assign a fixed index to mmc devices on rk3399 boards.")

The unconventional order (B, C, A) is due to the fact that sd_emmc_a is
(according to the comments) only used for SDIO.

AFAICS all boards either have both sd_emmc_b and sd_emmc_c or only one of
them enabled. So the alias order should match the previous non-async order
for all of them.

Revert "arm64: dts: amlogic: add missing ethernet reset ID"

It has been reported on IRC and in KernelCI boot tests, this change breaks
internal PHY support on the Amlogic G12A/SM1 Based boards.

We suspect the added signal to reset more than the Ethernet MAC but also
the MDIO/(RG)MII mux used to redirect the MAC signals to the internal PHY.

This reverts commit f3362f0c18174a1f334a419ab7d567a36bd1b3f3 while we find
and acceptable solution to cleanly reset the Ethernet MAC.

arm64: dts: meson: Fix IRQ trigger type for macirq

A long running stress test on a custom board shipping an AXG SoCs and a
Realtek RTL8211F PHY revealed that after a few hours the connection
speed would drop drastically, from ~1000Mbps to ~3Mbps. At the same time
the 'macirq' (eth0) IRQ would stop being triggered at all and as
consequence the GMAC IRQs never ACKed.

After a painful investigation the problem seemed to be due to a wrong
defined IRQ type for the GMAC IRQ that should be LEVEL_HIGH instead of
EDGE_RISING.

The change in the macirq IRQ type also solved another long standing
issue affecting this SoC/PHY where EEE was causing the network
connection to die after stressing it with iperf3 (even though much
sooner). It's now possible to remove the 'eee-broken-1000t' quirk as
well.

The ethmac node has to be configured for each board due to different
pinctrl nodes for RGMII/RMII. Thus the phy-mode should be specified at
the same place (= in the board .dts), making it easier to read the board
.dts file (because the phy-mode is stated explicitly, without requiring
developers to read all "parent" .dtsi as well).

Add the SAR ADC to meson-gxbb.dtsi and meson-gxl.dtsi. GXBB provides a

Some boards use resistor ladder buttons connected through one of the ADC
channels. On newer devices (GXL and GXM) some boards use pull-ups/downs
to change the resistance (and thus the ADC value) on one of the ADC
channels to indicate the board revision.
