The hog pinctrl hog is meant for pins that do not have an
associated driver.
The MX53_PAD_GPIO_0__CCM_SSI_EXT1_CLK pin is the one that
provides the MCLK signal to the SGTL5000 codec, so a
better represenation is to move it under the codec node.
While at it, change the pinctrl value from 0x80000000 to the
POR reset value of register IOMUXC_SW_PAD_CTL_PAD_GPIO_0.

The wake-up pin is pulled low with 100kOhm on the carrier board.
The current configuration of 100kOhm pull-up caused lots of
interrupts, especially during boot up. Make sure the pin is at a
reasonable level at startup by pulling it low on SoC side too.

Muxing the card detect only in the carrier board device tree
overwrites the USDHC muxing in the module level device tree.
Move card detect to the module level device tree since this
is also a default pinout of the Colibri standard. If a carrier
board requires a different setting it still can overwrite the
nodes in the carrier board specific device tree.

The OPPs for the A83T CPU cores were added in v4.17 in commit 2db639d8c1
("ARM: dts: sun8i: a83t: add stable OPP tables and CPUfreq"), but board
level regulator supplies for the CPU clusters were only added for the
TBS-A711 tablet. This means the other A83T boards do not benefit from
voltage scaling, or worse, if the implementation does not scale the
frequency when the voltage is fixed, no benefit at all.
Add board level CPU cluster power supplies to all the A83T development
boards, so they can have proper dynamic CPU voltage and frequency scaling.

This patch adds dt bindings to enable netcp network driver on K2G
ICE boards. This consists of enabling bindings for NSS qmss, pktdma,
2u ethss, mdio, pinmux and netcp devices as well as DP83867 phy.
EVM hardware spec recommends to add 0.25 nsec delay in the tx direction
and 2.25 nsec delay in the rx direction for internal delay in the clock
path to be on the safer side.
The board straps RX_DV/RX_CTRL pin of on board DP83867 phy in mode 1.
The phy data manual disallows this. Add ti,dp83867-rxctrl-strap-quirk
in the phy node to allow software to enable the workaround suggested for
this incorrect strap setting. This ensures proper operation of this PHY.

of a cluster or none. If these are present only for a subset of CPUs of
a cluster then things will start falling apart as soon as the CPUs are
brought online in a different order. For example, this will happen
because the operating system looks for such properties in the CPU node
it is trying to bring up, so that it can register a cooling device.
Add such missing properties.
