1056303148 ARM: dts: Migrate U-boot nodes to U-boot DT files for stm32h7
In order to prepare and ease future DT synchronization with kernel
DT, migrate all U-boot specific nodes/properties/addons to
U-boot DT files.

As sdmmc is not yet supported on kernel side, sdmmc nodes
are located in eval-u-boot and disco-u-boot DT files.

75d5853ffc serial: stm32x7: remove stm32f7-usart and stm32h7-usart compatible
This patch remove the extra compatibility string "st,stm32h7-usart"
and "st,stm32f7-usart" to avoid confusion, save some time & space.

a1e384b4d9 ARM: DTS: stm32: adapt stm32h7 dts files for U-boot
This patch adapts stm32h743 disco and eval dts files to match
with U-boot requirements or add features wich are not yet
upstreamed on kernel side :

_ Add RCC clock driver node and update all clocks phandle
  accordingly.

  By default, on kernel side, all clocks was temporarly
  configured as a phandle to timer_clk waiting for a RCC
  clock driver to be available.
  On U-boot side, we now have a dedicated RCC clock driver, we
  can configured all clocks as phandle to this driver.

  All this binding update will be available soon in a kernel tag,
  as all the bindings have been acked by Rob Herring [1].

  [1] http://lkml.iu.edu/hypermail/linux/kernel/1704.0/00935.html

_ Align STM32H7 serial compatible string with the one which will be
  available in next kernel tag. The bindings has been acked by
  Rob Herring [2].
  This compatible string will be usefull to add stm32h7 specific
  feature for this serial driver.

  [2] https://lkml.org/lkml/2017/7/17/739

_ Add gpio compatible and aliases for stm32h743

_ Add FMC sdram node with associated new bindings value to
  manage second bank (ie bank 1).

_ Add missing HSI and CSI oscillators nodes needed
  by STM32H7 RCC clock driver.

  Clock sources could be:
	_ HSE (High Speed External)
	_ HSI (High Speed Internal)
	_ CSI (Low Power Internal)

  These clocks can be used as clocksource in some configuration.
  By default, HSE is selected as clock source.

_ Set HSE to 25Mhz for stm32h743i-disco and eval board

  By default, the external oscillator frequency is defined at
  25 Mhz in SoC stm32h743.dtsi file.
  It has been set at 125 Mhz in kernel DT temporarly waiting for
  RCC clock driver becomes available.

  As in U-boot we got a RCC clock driver, the real value of HSE
  clock can be used.

_ Add "u-boot,dm-pre-reloc" for rcc, fmc, fixed-clock, pinctrl,
  pwrcfg and gpio nodes.
