The default eDP panel on RK3288 EVB board is LG LP079QX1-SP0V TFT LCD,
we haven't declared the panel regulator in the 'panel-simple' device
node here, so the specific board like ACT8846 / RK8080 need to support
the panel power supply.

Obviously emmc and sdio-wifi are non-removable devices, while
broken-cd is for removable device whose card detect pin is broken.

Keyboard driver for GPIO buttons(gpio-keys) checks for the legacy
"gpio-key,wakeup" boolean property to enable gpio buttons as wakeup
source.

Few dts files assign value "1" to gpio-key,wakeup and in one instance a
value "0" is assigned probably assuming it won't be enabled as a wakeup
source. Since the presence of the boolean property indicates it is
enabled, value of "0" have no value.

This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property which inturn fixes the above mentioned issue.

GPLv2-only devicetrees make reuse difficult for software components licensed
under a different license.

The consensus is that a GPL/X11 dual-license should allow all necessary uses,
so relicense the rk3288-evb files to this combination.

CCs were aquired by git shortlog -sne so it should've hopefully catched
every contributor.

Currently the hdmi driver is using one of the soc i2c busses for ddc probing
and while documentation always specifies i2c5 as hdmi-i2c it could very well
be any other bus as well.

Therefore this is a property of the board and should be specified there.

This enables the recently added display nodes on the firefly and evb,
letting the boards output graphic data over the hdmi port.

This includes enabling of i2c5 on the evb that is used for ddc probing and
setting the lcd-regulators to always on until the hdmi driver learns
about using them.

It seems that ever since (536f6b91 mmc: dw_mmc: Reset DMA before
enabling IDMAC) landed upstream that SD cards have been very unhappy
on rk3288-evb.  They were a little unhappy before that change, but
after that change they're REALLY unhappy.

It turns out that the above fix happens to fix a corruption when
reading card information during probe time.  Without the fix we didn't
detect that high speed SD cards could actually support high speed.
With the fix we suddenly detect that they're high speed and we try to
use them at 50MHz.  That doesn't work so well on EVB with the default
drive strength (maybe because there are two physical SD card slots
hooked up to the same pin?).

Fix the problem by bumping up the drive strength of the sdmmc lines.

The PMIC interrupt pinctrl line was added to the rk3288-evb-act8846,
but it's the same line on both the ACT8846 version and the RK808
version.  This makes a lot of sense since they share the same SoC
daugherboard.  Move the pinctrl definition to the common file so we
can use it for the RK808 version.

NOTE: The PMIC interrupt doesn't _actually_ go to the PMIC on the
ACT8846 version of the board (it does on the RK808), but our
convention is to label things as they're labelled on the schematics.
In the very least you can argue that this is the interrupt from the
PMIC daughtercard even if it doesn't actually go to the PMIC chip.

This enables basic SD and eMMC support.  Things are not yet running at
the fastest speed and we don't have the regulators specified, but we
can at least use the eMMC and SD cards now.

A note:
* Though MMC DDR50 mode is partially supported in the dw_mmc
  rk3288-specific code in Addy's patch, Addy's patch doesn't add
  tuning support.  That means DDR50 mode is not reliable.  From the
  3288 TRM: "Tuning is required for other speed modes-such as
  DDR50-even though the output delay from the card is less than one
  cycle."  Thus, we don't enable MMC DDR50 mode in this patch.
