[v4,00/42] ep93xx device tree conversion

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

The main goal is to receive ACK's to take it via Arnd's arm-soc branch.

Major changes:
- drop newline at the end from each YAML files
- rename dma and clk bindings headers to match first compatible
- shrink SoC exported functions number to only 2
- dropped some ep93xx_pata fixes from these series
- dropped m48t86 stuff from these series

Bit thanks to Andy Shevchenko for thorough review.

Some parts are were sent in advance, so these series depends on the
following:

Changes in v4:

- gpio: ep93xx: split device in multiple
  - s/generic_handle_irq/generic_handle_domain_irq/
  - s/int offset/irq_hw_number_t offset/ though now it looks a bit odd to me
  - drop i = 0
  - drop 'error'
  - use dev_err_probe withour printing devname once again

dt-bindings: clock: Add Cirrus EP93xx
  - renamed cirrus,ep93xx-clock.h -> cirrus,ep9301-clk.h

clk: ep93xx: add DT support for Cirrus EP93xx

  - expand example

soc: Add SoC driver for Cirrus ep93xx
  - s/0xf0000000/GENMASK(31, 28)/
  - s/ret/ep93xx_chip_revision(map)/
  - drop symbol exports
  - convert to platform driver

  - ok to fwnode_get_next_child_node
  - use goto to put handle and nand and report error

ARM: dts: add Cirrus EP93XX SoC .dtsi
  - add simple-bus for ebi, as we don't require to setup anything
  - add arm,pl011 compatible to uart nodes
  - drop i2c-gpio, as it's isn't used anywhere

ARM: dts: ep93xx: add ts7250 board
  - generic node name for temperature-sensor
  - drop i2c
  - move nand, rtc, watchdog to ebi node

You are welcome!

Dunno if you have used --patience when formatted the patches, but I think
you should, if hadn't, for the next version. It will help a lot in reviewing
and understanding the changes.
