cde669fa71 ARM: dts: rockchip: add Netxeon R89 board
This board is used in some TV-boxes like for example the Beelink R89 or
Tronsmart R28.

The board itself follows the reference design for the most part. But
there are no schematics available it seems, so some things should be
taken with a grain of salt.

98ce6007ef ARM: dts: overo: Support PoP NAND
Some Overo COM models include NAND flash in the on-board
package-on-package (PoP) chip.  Add this to the base Overo devicetree.

Most commonly, this is 512MB NAND from the Micron MT29C4G96MAZ family
but, as discussed [1], several different sized are possible. To
support different sizes, the last partition should fill to the end of
the chip (i.e. MTDPART_SIZ_FULL).

With thanks to Florian Vaussard for the original patch [2] and Adam Lee for
updating it here.

Add device nodes to make it really available.

We no longer have to depend on the on-board UART device (16550A),
so let's change the chosen and aliases to point to the on-chip ones.
Also, turn on the on-board Ethernet device.

1d8aca9df6 ARM: ux500: fix MMC/SD card regression
Ux500 is regressing due to commit
a21763a0b1
"pinctrl: nomadik: activate strict mux mode" which disallows
Nomadik GPIO 5 to be muxed in as a level shifter voltage select
pin, as it is currently described as being used for RX on UART1.

The behaviour is correct, instead the hardware config has been
incorrecly specified: UART1 is indeed unused on HREFv60plus and
Snowball and that is why HREFv60plus can use the pins it would
normally occupy as the voltage select line for the MMC/SD
levelshifter (Snowball uses it for I2C4).

The reason UART1 was anyway enabled on these platforms was
probably to secure the port enumeration to userspace. This
can be solved by using aliases (done in a separate patch) so
we can now deactivate UART1 and let MMC/SD use it properly
on HREFv60plus. We explicitly activate it only for the
older HREFprev60 board.

To complete, we set up the pin configuration for these pins
properly in the sdi0 node.
