The compatible string below was added to
rockchip-io-domain.txt, but never added to the device tree,
so add a io-domains node to rk3188.dtsi
"rockchip,rk3188-io-voltage-domain"

The compatible string "snps,dw-apb-timer-osc" was deprecated in place
of "snps,dw-apb-timer". Rename the timer compatible strings in
rk3066a.dtsi, so boot loaders like U-boot can use the timer node
directly without conversion.

Qualcomm dts updates for v5.15
This introduces the MSM8226 platform and an initial dts for the Samsung
Galaxy S III Neo phone.
MSM8974 gains another UART and this is used to enable Bluetooth on the
Sony Xperia Z2 Tablet. Samsung Galaxy S5 gains regulator definitions for
audio and modem remoteprocs, effectively enabling these.
DSI clocks on APQ8064 are updates as the old legacy clock names are no
longer supported by the driver. And IPQ806x GMAC nodes gains AHB resets
wired up.
Lastly APQ8060 is converted to a SPDX header and the ethernet node is
updates in accordance with the binding.

The function of each SoM pins is defined in the DHCOM standard [1] and
subset of them is defined as GPIOs (pins A-W). To ensure the interchange-
ability of the DHCOM SoMs, the function of the pins are fixed and cannot
be changed. On board level the DHCOM GPIOs can be used associated with
different blocks e.g. for interrupt or reset, but the function is always
GPIO. If not used, they can be freely used in the user space.
Therefore the whole configuration of SoM pins is made in the SoM DT.
Defining the DHCOM GPIO pins as a separate pinctrl nodes makes moving a
subset of them to an appropriate block pinctrl group easier on board level,
since it is not necessary to have a large pinctrl hog group containing
unrelated pinmux entries on board level. This also makes it easy to update
the SoM DT without having to update all the board DTs too. If necessary it
is also possible to change the electrical properties of the DHCOM GPIOs by
overwriting the pinctrl on board level.

The PDK2 board is capable of running both 100M and 1G ethernet. However,
the i.MX6 has only one ethernet MAC, so it is possible to configure
either 100M or 1G Ethernet. In case of 100M option, the PHY is on the
SoM and the signals are routed to a RJ45 port. For 1G the PHY is on
the PDK2 board with another RJ45 port. 100M and 1G ethernet use
different signal pins from the i.MX6, but share the MDIO bus.
This SoM board combination is used to demonstrate how to enable 1G
ethernet configuration.

The minimum available memory size of all DHCOM i.MX6 variants is 512 MB.
Set this value for the memory node. If U-Boot fails to fill the memory
size, at least all DHCOM i.MX6 variants should run without problems.
