This series aims to convert ep93xx from platform to full device tree support.

Alexander, Kris - there are some significant changes in clk and pinctrl so can i ask you to tests all once again.

So i am not applying:

Major changes from v0 to v1:

- I totally forgot to include dts bindings for USB, they are working, including in this version
- retinkered ep93xx keypad, the stange thing about it that it always used zeroed
platform data from the very beginning - my first impulse was to remove it entirely, espesially
it's ep9307+ variant, which Alexander and me doesn't have
- major YAML bindings overhaul according to Krzysztof comments
- nand helper converted to LEGACY nand controller
- cleanup clk
- cleanup pinctrl

Sorry if i missed something, first time handling such a big (at least for me) chunk of patches.

Next version should be much faster spin.

Alexandre Belloni:
st,m48t86 is totally trivial, but it has 2 regs instead of one, so dt_binding_check doesn't allow it in trivial.yaml,
regs should be increased to "maxItems: 2"

Miquel Raynal:
Currently made it LEGACY as a more easier way for now, as this series will merge - it will be much
easier to cleanup the rest one by one, i hope it's ok.

Stephen Boyd:
Majory of issues fixed, but:
- removing dma from init section requires converting it from half dt/platform monstrosity
into fully dt compatible
- i would like to have ep93xx_clk_data and ep93xx_map global for now - they can be removed
once dma subsys_initcall removed

Andrew Lunn:
I've tinkered with the preferred way, however this involves turning on
- CONFIG_PHYLIB
- CONFIG_MDIO_DEVICE

And maybe CONFIG_MICREL_PHY (at least for me, unless i can use some
common phy driver) which implies a kernel size increase - which is
undesirable for us.

Can we slip by getting phyid directly from device tree in ep93xx_eth ?
