io-voltage control is actually part of the grf, so move the node under the
newly available grf simple-mfd.

To minimize duplicate code, the core node and compatible property
gets placed in the core rk3288.dtsi while the individual boards
now only need to enable it and add the necessary supply properties.

Drop superfluous #address-cells and #size-cells, rename
key-nodes to individual names and also use the key constants

Only one of "broken-cd" and "non-removable" should be supplied
according to Documentation/devicetree/bindings/mmc/mmc.txt.
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.

It seems some firefly boards need 12mA drive strength for sdmmc.
Using 4mA/8mA drive strength will cause the kernel to fail to recognize
the sd card correctly.
Increased the sdmmc lines drive strength from 4mA to 12mA.

Add the iodomains node and reference the correct regulator for each
domain. This also includes adding the currently unused dvp regulators.

Fix some incorrect references to mmc regulators.
vccio_wl for example is the io-voltage supply not the core supply
of the wifi module itself, which is vbat_wl instead.

The memory node is supposed to contain a device_type property marking
it as memory. The currently included boards miss this property.

Adds ramp delay for the vdd_cpu output. It removes warning "ramp_delay
not set" emitted by the function regulator_set_voltage_time_sel() by the
same time, which floods kernel logs.

This was left out of the original firefly board definition due to the
ethernet support going completely through the network tree, making the
underlying nodes unavailable.

Now that everything is present enable the gmac on the firefly.

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.

This adds support for Firefly-RK3288, Rockchip RK3288 based development
boards made by Firefly.

There are 2 dts for 2 versions of the board. rk3288-firefly-beta.dts is
for the beta version, rk3288-firefly.dts is for the mass production version.
